AB  - Milk fat content stands out as a crucial production trait in cows, and this study delves into its variability based on various factors. The
research investigated how the housing method (large farm or individual producers), origin (domestic-rearing or imported cows), and
calving season collectively impact this trait. Cows reared on the farm exhibited a higher milk fat content compared to those raised by
individual producers. Additionally, primiparous cows from domestic rearing displayed lower milk fat content than their counterparts
of imported origin. Among primiparous cows on the farm, those calving in the summer and autumn produced the highest milk fat
content. Conversely, primiparous cows calving in the spring season and raised by individual producers recorded the lowest milk fat
content. The statistical analysis revealed a highly significant influence of calving season, with a noteworthy interaction among housing
method and origin on the observed trait. The significance ranged from statistically highly significant (P ≤ 0.01) to statistically very
highly significant (P ≤ 0.001).

AB  - The Krivovir pramenka was created by crossing silk-fleece rams from Asia with
local sheep. During World War II, it was crossed with Merino rams used for meat
production, while pure breed breeding for the purpose of preservation of this indigenous
population, started at the end of the 20th century. It is reared in eastern Serbia, more precisely
in the area of the Crna Reka basin, which is bordered by the mountains Rtanj, Čestobrodica
and Kučaj. The effective size of this population today is 315 heads, which makes it a
potentially endangered population. The first step in the preservation of this breed is
determining the morphometric characteristics of the animals.
The objective of the present study is to determine the phenotypic parameters of the
Krivovir pramenka as well as their indices, which would ultimately contribute to its
preservation, sustainable use, and improvement through selection work methods.
Morphometric tests were performed on 30 sheep, aged 3 years, reared in the area of
Stara planina in semi-extensive conditions. The diet was traditional, pasture and hay with
the addition of corn in the winter period. The variability of the morphometric parameters
was determined using Lidtin stick and ribbon. The following exterior body measurements
were determined: height to withers, body length, chest width, chest depth, tail length, chest
circumference, pelvis width, shin circumference, head length, head width, earslength, neck
girth, height of the back and height of the pelvis. Indices of body development are calculated
values, expressed in percentages, and represent the ratio of the absolute values of the
measurement in relation to another body measurement.
The descriptive statistical procedure was performed using the statistical package
STATISTICA (version 8). The average height to withers of the sheep was 62.35 cm, body
length 70.14 cm, chest width 16.60 cm, chest depth 26.57 cm, chest circumference 92.82 cm
and shin circumference 7.94 cm. Krivovir Pramenka had a higher index of format, body
compactness, massiveness and leg length, compared to sheep of Pirot and Travnik Pramenka
breed and Vitorog Žuja breed sheep.
By comparing the results of this study with the results of earlier research conducted
on this sheep strain, the conclusion is that the Krivovir sheep today is slightly larger, longer,
with a stronger skeleton, which may be a consequence of changed management.

AB  - Visual assessment and recognition of milk performance traits of cows are preliminary indicators of milk yield, longevity, as well as reproductive abilities of the animal, which is very important from the aspect of economy of milk production. Deficiencies in udder traits lead to poorer production, difficult milking and premature weaning of cows from the herd. The paper examines the frequency of desirable scores for a certain trait in first-calving heifers distinguished by way of keeping (heads reared by individual producers/holdings and heads reared on the farm) and by origin (domestic and imported animals), as well as the influence of these two factors on the observed traits. Five udder traits were analyzed: front udder length, rear udder length, rear udder height, central ligament, and udder depth on a total of 954 first-calving Simmental heifers. Observed by the way of rearing, higher frequency of desirable scores for all udder traits were achieved by cows reared on the farm, while according to the origin of cows, higher frequency of desirable scores for all udder traits was achieved by imported cows compared to domestic cows. The influence of factors of housing/keeping and origin, examined by χ2 test on all examined linear scores (frequency of scores) of udder traits was statistically very highly significant (p≤0.001), while the analysis of variance (F test) showed very high significance (p≤0.001) of interaction of origin and method of rearing on the traits of the central ligament and the udder depth, and significance (p≤0.05) on the height of the rear udder, however, no statistical significance (p>0.05) of this interaction was established on other linear scores of udder traits (length of the front and rear udder).

AB  - The aim of this research was to investigate the influence of the bull age on production and some semen quality traits. The semen was collected during 2014. The LSD test (Least Significant Difference) was used to compare the bulls of different age groups and the results of this test showed in some cases significant differences. This test showed that there was no significant difference in ejaculate volume between six-year-old and four-year-old bulls, but in two-year-old bulls a significant difference to older bull groups was determined. The results showed that there was a significant effect of the bull age (p<0.001) on the ejaculate volume and the number of doses per ejaculate.

Cows were located in the area of Toplica district, reared on individual farming households (tied system) and on the farm with intensive farming (free system). Based on the rearing method and origin, animals were divided into four groups: Group 1 (domestic animals reared by individual agricultural producers on individual farming households); Group 2 (imported animals reared by individual agricultural producers on individual farming households); Group 3 (domestic animals reared on the farm) and Group 4 (imported animals reared on the farm). The fourth group of studied cows showed the highest yield and protein content, while the cows of the third group had the longest lactation and the highest milk fat content. All production performance traits varied highly significantly (p≤0.001) under the influence of the combined factor of housing/rearing method and origin.

AB  - The aim of this study was to determine the frequency of the κ-casein and β-lactoglobulin genotypes of the daughters of 5 Simmental bulls (sires) used for insemination in Serbia. Blood samples were taken from a total of 157 cows of the Simmental breed in Toplica and Rasina districts. Cows from which blood samples were taken were the daughters of the following bulls: Rorb B033, Dionis B52, Val B064, Rondi B029 and Res 1433. In all daughters of studied bulls, the presence of all three genotypes was determined, except for daughters of bull sire Res B1433, where the absence of genotype BB was determined. In addition to determining the frequency of genotypes and alleles for both milk protein fractions, based on the χ2 test, a link between the sire and the presence of genotypes was determined, and in both cases a statistically significant relationship (p≤0.001) was found.

Uzorci krvi uzeti su iz ukupno 157 krava simentalske rase u Topličkom i Rasinskom okrugu. Krave od kojih su uzeti uzorci krvi bile su ćerke sledećih bikova: Rorb B033, Dionis B52, Val B064, Rondi B029 i Res 1433. Kod svih ćerki, ispitivanih bikova, utvrđeno je prisustvo sva tri genotipa, osim kod ćerki bika Res B1433, kod kojih je utvrđeno odsustvo genotipa BB. Pored određivanja frekvencija genotipova i alela za obe frakcije proteina mleka, na osnovu χ2 testa urađeno je ispitivanje veze između očeva i zastupljenosti genotipova, i u oba slučaja je utvrđeno da postoji statistički značajna veza (p≤0,001).

In addition to determining the frequency of genotypes and alleles for both milk protein fractions, based on the χ2 test, a link between the sire and the presence of genotypes was determined, and in both cases a statistically significant relationship (p≤0.001) was found., Cilj ovog istraživanja bio je da se utvrdi frekvencija genotipova κ-kazeina i β-laktoglobulina ćerki 5 bikova (očeva) sementalske rase koji se koriste za osemenjavanje u Srbiji. Uzorci krvi uzeti su iz ukupno 157 krava simentalske rase u Topličkom i Rasinskom okrugu. Krave od kojih su uzeti uzorci krvi bile su ćerke sledećih bikova: Rorb B033, Dionis B52, Val B064, Rondi B029 i Res 1433. Kod svih ćerki, ispitivanih bikova, utvrđeno je prisustvo sva tri genotipa, osim kod ćerki bika Res B1433, kod kojih je utvrđeno odsustvo genotipa BB. Pored određivanja frekvencija genotipova i alela za obe frakcije proteina mleka, na osnovu χ2 testa urađeno je ispitivanje veze između očeva i zastupljenosti genotipova, i u oba slučaja je utvrđeno da postoji statistički značajna veza (p≤0,001).",

AB  - The aim of this research was to investigate the influence of the
bull i.e. genotype on the observed traits of semen quality and to determine whether
there are significant differences between bulls in terms of semen production. The
study included 9 bulls of the Holstein-Friesian breed from the Livestock Center of
PKB Corporation. The effect of the bull on certain semen properties (ejaculate
volume, sperm concentration, sperm motility in the native ejaculate, sperm
dilution, number of doses per ejaculate, sperm motility after thawing) was analyzed
and data were collected during 2014. During this period, a total of 326 ejaculates
from 9 bulls were collected and average values for the tested properties were
determined and the effect of the bull on those properties was analyzed. The results
showed that there was a very significant effect of the bull (p<0.001) on the degree
of sperm dilution and the number of doses per ejaculate. Significant influence
(p<0.01) was found in ejaculate volume traits, sperm concentration, sperm motility
in the native ejaculate, while in sperm motility after thawing no significant effect
(p> 0.05) of the bull was determined. The LSD test (Least Significant Difference)
was used to compare the bulls and the results of this test showed in most cases
significant differences between the bulls.

AB  - Problems with legs and various forms of lameness of cows, in intensive milk production, are the third significant problem occuring in this production, after mastitis and reproductive disorders, both globally and in our country. The paper analyzes the incidence of the deformation of legs of 145 cows of the Simmental breed in the Kolubara region, and the influence of paragenetic factors (housing/holding and type of stall/bedding and lactation) on the incidence of deformations. The obtained results show that, of the total number of cows assessed, 3.45% had 'X' position of the front legs, 14.8% had a 'X' position of the hind legs. The convergent position of the front legs was recorded in 35.86%, and divergent in 8.28% of animals. The convergent position of the hind legs was observed in 16.55% of cows, and divergent in 2.76%. The outward position of the front legs was observed in 4.14% of cows, inward position in 11.03%, and broad position in 4.14% of studied cows. Also, 17.24% of the cows had a so called sable like position of hind legs, and 7.59% showed steap angle of hind legs. The pronounced soft front leg pasterns were observed in 7.59% of the cows, and the soft pasterns of the hind legs in 33.79% of the total number of observed cows. The observed changes in the ankles in the shape of swelling were recorded in 1.38% of cattle on the carpal joint and 2.76% on the tarsal ankle. The damaged shoulder and body joint (scabbed shoulder) was observed in 43.45% of the total number of cows evaluated. Scores for the front and hind legs front, back and side views, varied at different levels of significance under the influence of the type of stall/bedding, while the scores for the condition of the hind leg pasterns varied highly significantly (p (lt) 0.001) under the influence of the type of stall/bedding. The scores for the front leg pasterns and scores for shoulder and body joint were not significant (p> 0.05) depending on the type of stall/bedding and the method of housing/holding of cows.

AB  - The objective of this study was to determine the frequency of the kappa-casein and beta-lactoglobulin genotypes in the Simmental cattle in Serbia and compare it with the frequency according to the Hardy-Weinberg equilibrium law. Blood samples were taken from a total of 157 cows of the Simmental breed in Toplica and Rasina districts. Of the 157 cows included in this study, the AA kappa-casein genotype was found in 53 cows, which makes a frequency of 33.80%, the AB genotype in 81 cows or 51.60% and the BB genotype in 23 cows or 14.60%. The allelic frequency A was 59.60%, while allele B had a frequency of 40.40%. In regard to the frequency of genotypes and beta-lactoglobulin alleles for the total studied population of cows obtained for AA, AB and BB genotypes for beta-lactoglobulin, was 33.10%, 49.70% and 17.20%, respectively, which means that 52 animals had genotype AA, 78 genotype AB and 27 genotype BB. The frequency of alleles A and B resulting from the incidence of genotypes was 58.00% for allele A and 42.00% for allele B. The specified frequencies for both protein fractions statistically differed significantly from the frequency according to the Hardy-Weinberg equilibrium law, which confirmed the absence of equilibrium in the examined population.

AB  - Assessment of cows' exterior is important because of the assessment of the capability of animals to guarantee, through their overall exterior appearance as well as the appearance of certain parts of the body, not only their good health but also long production life (longevity). The main goal of measuring of domestic animals is to determine the body dimensions, to compare animals of the same or different species, to understand the numerous physiological and biochemical processes that occur in the animal organism. Only by measuring, the accurate and reliable data on the general physical development of the animal and the harmony of its structure are obtained. In the present study, most of the physical measures were taken on total of 954 animals.

AB  - The study, which included 9 Holstein-Friesian bulls from the Livestock Center of the PKB Corporation, analyzed the impact of the ejaculate collection season on certain semen properties (ejaculate volume, sperm concentration, sperm motility in native ejaculate, sperm dilution, number of doses of one ejaculate and mobility of spermatozoa after thawing). For the purposes of this analysis, data for the three-year (2011-2013) and one-year period (2014) were used. In the three-year period, based on 621 ejaculates of three bulls, the average values for examined properties were calculated and the season's impact on these properties analyzed. The results show that the ejaculate collection season had a very significant effect (p<0.001) on the sperm motility in native ejaculate, and a significant effect (p<0.05) on the level of dilution of ejaculate and the mobility of spermatozoa after thawing. In the single-year period, based on 326 ejaculates from 9 bulls, the average values of the studied properties were calculated, and the influence of the season was also analyzed. The ejaculate collecting season showed a very high impact (p<0.001) on the mobility of spermatozoa after thawing, but no significant effect was found on other properties (p> 0.05).

AB  - Busha is small body native breed. It is found where the economic conditions are modest, and agriculture extensive. The intensification of livestock production, and the introduction of more productive, specialized breeds, caused diminished interest in growing Busha. Thus, Busha, as cattle oftriple productive properties, is largely suppressed, so that today we can rarely find examples of the pure breed. To protect specific geno-fund of this breed, the assessment of the level of endangerment of Busha population was carried out, which pointed to the risk status of the population and the necessity of the implementation of conservation programs. The paper analyzes the characteristics of physical development 138 Busha cows in the area of Pirot District, and the influence of non-genetic factors (farm, calving year, calving season) on the variability of traits. The average body weight of Busha cows in the area of Pirot District was 226.07 kg, height at withers 104.33 cm, rump height 104.12 cm,pelvis width 32.52 cm, chest depth 53.97 cm, chest circumference 130.48 cm and body length 119.67 cm. The analysis of the impact of non-genetic factors, showed a highly significant effect (p <0.01) of the farm on all the traits except the width of the pelvis, year of calving exerted a significant effect (p <0.01) on all traits of body development, whereas the calving season exerted no influence (p> 0.05) on any of the seven traits that have been studied.

AB  - The conducted research was aimed at constructing equations of selection index that would be used in the selection of the Holstein-Friesian breed animals in Serbia. The construction of the selection index includes the most important milk traits observed in standard lactation: milk yield (MY305), milk fat content (% MF305) and protein content (% MP305). The variance and covariance necessary for the construction of selection index are calculated using the mixed model by the method of least squares. The economic value of traits is expressed as a ratio of relative changes in costs per unit of traits included in the selection index. Livestock included in the research produced, in the first standard lactation, an average of 7681 kg of milk with 3.58% milk fat and 3.28% protein. The equation of the selection index presented in the paper is selected from the group of equations of selection index, as an equation with the highest correlation between the equation and the aggregate genotype, which amounted to 0.2156.

AB  - This research paper gives an analysis on the size of world's domestic buffalo populations, their milk production and the size of buffalo population in Serbia. Population of domestic buffalo in the world is constantly increasing so that in 2013 there were 199 783 549 individuals, out of which in India in the same year they raised 57.77% of buffalo world population, in Pakistan 18.87%, and in China 11.64%. The share of total world production of buffalo milk in total world milk production in 2012 was 12.92 % or 97 417 135 t out of which 67.76% was produced in India. In Serbia buffalo is raised in the regions of Raška (about 1000 individuals) and Kosovo. Populations of buffalo in central Serbia show a tendency of decreasing in size what was the reason to start a programme of in situ conservation 10 years ago. On the sample of buffalo population encompassed by the programme of conservation the body measures were analysed indicating that the population of buffalo is quite unequalised and that average values obtained for exterior measures are similar to the results obtained by the authors of earlier period for the population of buffalo in the area of former Yugoslavia.

AB  - The aim of this research was to determine if there are differences in sexual reaction of the grown sheep II de frans breed depending on the body weight of treated eves during induction and synchronization of estrus with fluorogestonacetate (FGA) + PMSG in anoestrus season. Total number of 262 eves was treated and they were divided in to three groups. The first group consisted of the sheep whose body weight was from 40 to 50kg, the second group of the sheep whose weight was from 50-60kg and the third group of the sheep whose weight was above 60kg. Each group received sponges of FGA. After removal of the sponges all sheep received intramuscular injection of 500 i.u of PMSG. The 'Sugonal' prepared by Veterinary institute Subotica was used. After two days the insemination was conducted. The results show that from first group 43.78% sheep lambed, from second group 46.66% and from third group 59.32%. Average sheep fertility after treatments was for the first group 113.28%, 118.37% for the second group and 137.14% for the third group. The ratio of singles, twins and triplets was for the first group 72:28:0 %, for the second group 70.69:24.14:5.17%, and for the third group 47.92:45.83:6.25%. Determined differences between number of lambed sheep and treated sheep, fertility and number of twins, as well as between investigated groups were statistically significant (P (lt) 0,05). Conclusion is that sheep of body weight above 60kg have had significantly better reaction to the treatment.
AB  - Cilj ovog istraživanja je da se utvrdi da li postoje razlike u polnom reagovanju odraslih ovaca rase II d,frans u zavisnosti od telesne mase tretiranih plotkinja pri indukciji i sinhronizaciji estrusa pomoću fluorogeston acetata (FGA) i gonadotropnog hormona gravidnih kobila (SGŽK ili PMSG) u sezoni anestrije. Ukupno je tretirano 262 plotkinje, podeljene u tri grupe. UI grupu svrstane su ovce telesne mase 40-50 kg t.m., u II grupu 50-60 kg t.m. i u III grupu > od 60 kg t.m. (kontrolna grupa). Životinjama svih grupa intravaginalno su aplikovani sunđeri (30 mg fluorogeston acetata/sunđer) koji su ostali u vagini 12 dana. Na dan vađenja sunđera, ovcama je s.k., jednokratno aplikovan SGŽK u dozi od 500 i.j./grlo. Nakon dva dana izvršen je 'pripust iz ruke'. Dobijeni rezultati pokazuju da se iz I grupe ojagnjilo 43,78%; iz II 46,66% a iz III 59,32% tretiranih plotkinja. Prosečna plodnost ovaca po tretmanima I, II i III je iznosila 116,28% kod I grupe, 118,37% Il grupe, sto je ispod očekivanih vrednosti za rasu, dok je plodnost od 137,14% kod III grupe u granicama prosečnih vrednosti za rasu. Utvrđene razlike između ispitivanih grupa, u korist III grupe u odnosu na I i II grupu, bile su statistički značajne (P (lt) 0,05). Zaključak je da su ovce III grupe prosečne telesne mase od 67,68 kg, znatno bolje reagovale na primenjeni tretman jer je postignuta očekivana plodnost.

AB  - Sheep have the ability to transform the relatively low quality food into high quality protein of animal origin (meat, milk). To increase the efficiency of feed utilization and minimize pollution of the environment, it is necessary to better understand the needs of lambs in nutrients (primarily energy and protein) and their interaction in the organism. Optimal ratio between energy and protein in the diet of lambs optimizes microbial protein synthesis and maximum retention of degradable nitrogen in the rumen. The excess of the energy consumed in the diet, will be transformed into fat, as the degree of increase of muscles and bones is limited. Feeding lambs diets deficient in the protein, leads to the formation of large amounts of fat in the body. The decline in the efficiency of energy use, in case of the surplus of protein in the diet, is associated with energy consumption for the formation and excretion of urea.
The results of our study showed that lambs crosses of Pirot Pramenka Wuerttemberg x Ile de France of average body weight of about 15 kg and 30 days of age and fed with a diet containing 4% beef tallow (7.71 MJ NEM and 16% CP) realized significantly (P<0.05) higher average daily gain and final body weight compared to animals that have consumed feed with 6% beef tallow and 7.94 MJ NEM. Also, animals on this treatment realized the best conversion of dry matter, protein and energy. The above nutritive treatment did not significantly affect the meat yield, the yield of meat per categories and morphological composition of the carcass side.Bearing this in mind, the aim of this paper is to present our own, and the results of other authors, related to the optimization of energy and protein levels in diets for fattening lambs.

AB  - The work is the presentation of performance data and phenotypes of milk traits of Simmental cows in Serbia. The analysis of quantitative phenotypic parameters was carried out in four breeding areas and on dozen of large and small farms housing and rearing 1370 cows – first calving heifers. The obtained data were analysed using the method of Least Squares and analysis results were obtained by applying mathematical-statistical data analysis using mixed models. Mathematical - statistical analysis of data was performed using linear methods with fixed effects, using the method of Least Squares (LS method).
Based on these results, it was established that the breeding area, statistically analysed, caused highly significant deviations (P <0.01) of production traits from the general population average. Calving season has influenced significantly (P<0.05), and the interaction of area and calving season has produced a highly significant variation in milk yield, milk fat and protein (P <0.01).

AB  - In this paper, results of the study of the effect of different protein sources in concentrate mixtures on fluid rumen content and digestibility of nutrients in fattening lambs are presented. Physiological study included 18 male lambs of MIS population, average body mass of approx, 35.0 kg, divided into three groups. Lambs were fed isoprotein concentrate mixtures (14% CP) which differed about protein source: sunflower meal (I), soybean meal (II) and fishmeal (III), resulting in different ratio of protein non-degradable in rumen: 43% (I), 51% (II) and 58% (III), respectively. Content of ammonia nitrogen (NH3-N) in rumen fluid of fattening lambs in said treatments was 42.46: 33.86: 31.35 mg/100 ml. pH rumen value in treatments I: II: III were 6.56: 6.35: 6.15. Trial results show that the level of protein intake was not under significant influence of studied treatment, considering that digestibility coefficients were 52.58%: 51.30%: 55.12%. With the increase of the share of non-degradable protein in concentrate mixtures, the tendency of fat digestibility increase was observed: 76.13: 77.98: 87.17%, also of decrease of cellulose intake: 67.40: 45.87: 22.39% and NFE: 83.87: 76.05: 82.96%.

AB  - This study examines the impact of two-breed (PXW) and three- breed (PxWxIDF) system of sheep crossing on the results in terms of yield and quality of meat of lambs, weaned at 60 days of age and fattened up to 120 days of age. Study was carried out on the experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and the following breeds of sheep were used for crossing: Pirot pramenka (P) Württemberg (W) and Ile de France (IDF). As maternal basis the Pirot Pramenka and two breed crosses were used, and as improvement breed - Ile de France rams. Pre-slaughter body mass of two-breed and three-breed crosses was: 32.63 and 34.48 kg. Values of dressing percentage warm carcass with head and offal were: 59.0 and 58.4%. The share of the category I meat on analogue treatments was: 37.07: 37.48%, meat of category II: 33.98: 32.41%, and the meat of category III - 28.69: 26.87%. Meat to bone ratio was: 2.3:1 in two- breed crosses, whereas in the three-breed crosses it was 2.7:1. MLD surface was 11:49 and 11:45 cm2. Regarding the chemical and technological characteristics, there were no significant differences among the treatments (P> 0.05).
AB  - U radu je ispitivan uticaj dvorasnog (PxW) i trorasnog (PxWxIDF) sistema ukrštanja ovaca na rezultate u pogledu prinosa i kvaliteta mesa jagnjadi zalučene sa 60 dana i tovljene do 120 dana uzrasta. Istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun, a za ukrštanje su korišćene sledeće rase ovaca: Pirotska pramenka (P), Virtemberg (W) i Ile de France (IDF).Kao materinska osnova korišćeni su Pirotska pramenka i dvorasni melezi, a kao oplemenjivači - ovnovi Ile de France. Ishrana grla krmnim smešama je bila grupna i po volji, dok je količina sena ograničena i ravnopravno distribuirana. Na kraju ogleda, radi utvrđivanja prinosa i kvaliteta mesa, izdvojeno je i žrtvovano ukupno 18 grla (po 9 iz svake grupe).Statistička obrada dobijenih podataka je izvršena koršćénjem programa Stat.Soft, Inc (2003) STATISTICA (data analysis software system), version 6, primenom standardnih matematičko-statističkih metoda. Telesna masa pred klanje meleza iz dvorasnog i trorasnog sistema ukrštanja je iznosila: 32.63 i 34.48 kg.Vrednosti randmana toplog trupa sa glavom i iznutricama su iznosile: 59.0 i 58.4%.Udeo mesa I kategorije na analognim tretmanima je iznosio: 37.07 : 37.48%, mesa II kategorije: 33.98: 32.41%, dok je meso III kategorije bilo zastupljeno sa 28.69 : 26.87%. Odnos mesa prema kostima je bio: 2.3:1 kod dvorasnih meleza, dok je kod trorasnih iznosio 2.7: 1. Površina MLD je iznosila 11.49 i 11.45 cm2.U pogledu hemijskih i tehnoloških osobina, nije bilo značajnih razlika između ispitivanih tretmana (P>0.05).

abstract = "This study examines the impact of two-breed (PXW) and three- breed (PxWxIDF) system of sheep crossing on the results in terms of yield and quality of meat of lambs, weaned at 60 days of age and fattened up to 120 days of age. Study was carried out on the experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and the following breeds of sheep were used for crossing: Pirot pramenka (P) Württemberg (W) and Ile de France (IDF). As maternal basis the Pirot Pramenka and two breed crosses were used, and as improvement breed - Ile de France rams. Pre-slaughter body mass of two-breed and three-breed crosses was: 32.63 and 34.48 kg. Values of dressing percentage warm carcass with head and offal were: 59.0 and 58.4%. The share of the category I meat on analogue treatments was: 37.07: 37.48%, meat of category II: 33.98: 32.41%, and the meat of category III - 28.69: 26.87%. Meat to bone ratio was: 2.3:1 in two- breed crosses, whereas in the three-breed crosses it was 2.7:1. MLD surface was 11:49 and 11:45 cm2. Regarding the chemical and technological characteristics, there were no significant differences among the treatments (P> 0.05)., U radu je ispitivan uticaj dvorasnog (PxW) i trorasnog (PxWxIDF) sistema ukrštanja ovaca na rezultate u pogledu prinosa i kvaliteta mesa jagnjadi zalučene sa 60 dana i tovljene do 120 dana uzrasta. Istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun, a za ukrštanje su korišćene sledeće rase ovaca: Pirotska pramenka (P), Virtemberg (W) i Ile de France (IDF).Kao materinska osnova korišćeni su Pirotska pramenka i dvorasni melezi, a kao oplemenjivači - ovnovi Ile de France. Ishrana grla krmnim smešama je bila grupna i po volji, dok je količina sena ograničena i ravnopravno distribuirana. Na kraju ogleda, radi utvrđivanja prinosa i kvaliteta mesa, izdvojeno je i žrtvovano ukupno 18 grla (po 9 iz svake grupe).Statistička obrada dobijenih podataka je izvršena koršćénjem programa Stat.Soft, Inc (2003) STATISTICA (data analysis software system), version 6, primenom standardnih matematičko-statističkih metoda. Telesna masa pred klanje meleza iz dvorasnog i trorasnog sistema ukrštanja je iznosila: 32.63 i 34.48 kg.Vrednosti randmana toplog trupa sa glavom i iznutricama su iznosile: 59.0 i 58.4%.Udeo mesa I kategorije na analognim tretmanima je iznosio: 37.07 : 37.48%, mesa II kategorije: 33.98: 32.41%, dok je meso III kategorije bilo zastupljeno sa 28.69 : 26.87%. Odnos mesa prema kostima je bio: 2.3:1 kod dvorasnih meleza, dok je kod trorasnih iznosio 2.7: 1. Površina MLD je iznosila 11.49 i 11.45 cm2.U pogledu hemijskih i tehnoloških osobina, nije bilo značajnih razlika između ispitivanih tretmana (P>0.05).",

AB  - In this paper, the effect of different systems of crossing of sheep: two-breed (PxW) and three-breed (PxWxIDF) on production results - body weight and average daily gain of lambs weaned at the age of 60 days and fattened to age of 120 days, was investigated. Also, the effect of crossing on consumption and conversion of food and nutrients was monitored. Study was carried out on the Experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and following breeds were used in the crossing: Pirot Pramenka (P), Wurttemberg (W) and Ile de France (IDF). Pirot Pramenka was used as the maternal basis, while Wurttemberg rams were used as sires, and as terminal breed, Ile de France rams were used. Results have shown that the three-breed crosses of F1 generation, compared to two-breed crosses, obtained higher body gain for 19.23% with lower food intake for 5.19%, during fattening period lasting from 60th to 120th day of age. Regarding feed conversion ratio, they used per 1 kg of body gain 29.61% less hay and 20.82% less concentrate feeds. Positive biological effect exhibited in three-breed crosses (PxWxIDF) is consequence of individual heterosis and maternal heterosis.

Istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun, a za ukrštanje su korišćene sledeće rase ovaca: pirotska pramenka (P), virtemberg (W) i Il de frans (IDF). Rezultati su pokazali da su trorasni melezi u odnosu na dvorasne, u tovu od 60. do 120. dana uzrasta ostvarili za 19.23% veći prirast i za 5.19% manje konzumiranje hrane. U pogledu konverzije hrane, po kg prirasta su utrošili za 29.61% manje sena i za 20.82% manje koncentrata. Pozitivan biološki efekat koji se ispoljio kod meleza (PxWxIDF) je posledica korišćenja heterozisa individue i heterozisa majke.

AB  - Grasslands represent significant natural resource with important role in economy and ecology of every country. Properly cultivated and utilized grasslands provide cheap and high quality food for sheep, which they easily transfer into milk and meat. However, extensive management has caused degradation of pasture areas. Improvement of production of forage plants on pastures is achieved by using melioration measures, primarily fertilization. Fertilization is important also from the aspect of increase of yield and quality of forage plants. The effect of application of fertilizer depends on the present plant species in the mixture. Application of nitrogen mineral fertilizers in mixtures reduces the nitrogen fixating abilities of leguminous species, which leads to the diminishing of their competitive abilities and favouring of the grass component in the mixture. Use of excessive quantities of N fertilizer in plants causes the accumulation of nitrates, as a unfavourable quality parameter in plant tissues, which can have harmful effect on animal health. Therefore, attention should be focused on application of N fertilizers, which should be harmonized with the plant requirements, so that used quantities are not excessive and harmful. Objective of this paper is to point out the significance of fertilization as one of the most important melioration measures.

AB  - Exceptionally important aspect in cattle production, from the aspect of production and economy, is ensuring normal and regular fertility. Every cattle breeder wants to have high-yielding animals which at the same time have good fertility. In proper cattle breeding this means that from each cow during single year one healthy calf is obtained. Use of artificial insemination has enabled that one breeding male is used as sire for several tens of thousands of progeny, however, there is always the risk that sires could be carriers of lethal and semi-lethal genes, which can cause huge losses of calves. In order to bring these undesirable occurrences to a minimum, so called bilogical test is included in the breeding and selection activities, i.e. bulls are tested through their progeny for presence of difficult calving (dystocia) abd calf losses caused by genetic anomalies. In Republic of Serbia, this test is carried out on ehtire Simmental population in an exchange of data produced by primary breeding organizations. Per each tested bull, it is necessary to have data on minimum 50 randomly selected calves. Calves are examined visually 65 days after the birth, at the latest. In the present study, the results of the biological testing of 35 Simmental bulls, sires of total 3572 calves on the territory of Central Serbia, in the period 2008-2009, are used. The effect of sires on parameters of biological test were studied: body mass of calves at birth, calf score and calving score. Also, bulls were ranked based on said parameters, male/female calves ratio and percentage of twins and still-born calves for each bull individually were determined. After the rank of bulls was established, the correlation between the rank and studied fertility traits was determined. Correlations were expressed using the Spearman coefficient. Research results show that the effect of bulls was very high p (lt) 0,001 on all three parameters of the biological test, and also that the percentage of still born calves for all bulls was within limits, with the exception of bulls Zahlo (HB 1497) and Woz (HB 1433) where it was above 5.
AB  - Izuzetno važan aspekt u govedarskoj proizvodnji, gledano sa proizvodnog i ekonomskog stanovišta je obezbeđivanje normalne i redovne plodnosti. Svaki odgajivač goveda želi da ima grla koja su visoko proizvodna i istovremeno poseduju dobru plodnost. Za pravilno odgajivanje goveda to znači da se od svake krave u toku godine dobije po jedno zdravo tele. Upotreba veštačkog osemenjavanja omogućila je da jedan priplodnjak bude otac nekoliko desetina hiljada potomaka. Međutim, uvek postoji rizik da su očevi nosioci letalnih i semiletalnih gena, što može prouzrokovati velike gubitke teladi. Da bi se ove nepoželjne pojave svele na najmanju moguću meru u odgajivački i selekcijski rad uključeno je ispitivanje bikova po potomstvu na teška teljenja i gubitke teladi izazvane genetskim anomalijama, tzv. biološki test. Ovaj test se u Republici Srbiji vrši jedinstveno za čitavu populaciju simentalske rase, razmenom podataka između odgajivačkih organizacija. Po svakom biku koji se testira, neophodno je imati podatke za najmanje 50 slučajno odabrane teladi. Vizualni pregled teladi se obavlja najkasnije do 65 dana, od datuma rođenja teleta. U ovom istraživanju korišćeni su rezultati biološkog testa 35 bikova simentalske rase koji su bili očevi ukupno 3572 teladi na teritoriji centralne Srbije u periodu 2008. i 2009. godine. U radu je ispitivan uticaj očeva na parametre biološkog testa: telesnu masu teladi po rođenju, ocenu teleta i ocenu toka teljenja. Takođe je izvršeno rangiranje bikova na ove parametre, kao i utvrđivanje odnosa muške i ženske teladi, procenat bližnjenja kao i procenat mrtvorođene teladi za svakog bika posebno. Nakon utvrđenog ranga bikova izvršena je korelacija ranga ispitivanih osobina plodnosti. Korelacije su iskazane Spirmanovim koeficijentom. Rezultati istraživanja pokazali su da je uticaj bikova izuzetno visok p (lt) 0,001 na sva tri parametra u biološkom testu, kao i da je procenat mrtvorođene teladi kod svih bikova u dozvoljenim granica, osim bikova Zahlo (HB 1497) i Woz (HB 1433) gde je iznosio preko 5.

Ovaj test se u Republici Srbiji vrši jedinstveno za čitavu populaciju simentalske rase, razmenom podataka između odgajivačkih organizacija. Po svakom biku koji se testira, neophodno je imati podatke za najmanje 50 slučajno odabrane teladi. Vizualni pregled teladi se obavlja najkasnije do 65 dana, od datuma rođenja teleta. U ovom istraživanju korišćeni su rezultati biološkog testa 35 bikova simentalske rase koji su bili očevi ukupno 3572 teladi na teritoriji centralne Srbije u periodu 2008. i 2009. godine. U radu je ispitivan uticaj očeva na parametre biološkog testa: telesnu masu teladi po rođenju, ocenu teleta i ocenu toka teljenja. Takođe je izvršeno rangiranje bikova na ove parametre, kao i utvrđivanje odnosa muške i ženske teladi, procenat bližnjenja kao i procenat mrtvorođene teladi za svakog bika posebno. Nakon utvrđenog ranga bikova izvršena je korelacija ranga ispitivanih osobina plodnosti. Korelacije su iskazane Spirmanovim koeficijentom. Rezultati istraživanja pokazali su da je uticaj bikova izuzetno visok p (lt) 0,001 na sva tri parametra u biološkom testu, kao i da je procenat mrtvorođene teladi kod svih bikova u dozvoljenim granica, osim bikova Zahlo (HB 1497) i Woz (HB 1433) gde je iznosio preko 5.",

AB  - Defined geographic area with their specifity regarding unique plant species and autochthonous breeds - Sjenica and Pirot Pramenka, among traditional cheese-making practice of local community, are prerequisite for protection of denomination of geographic origin of Sjenica cheese and Pirot kachkaval. Sjenica cheese belongs to the group of soft, white cheeses in brine and it is produced as autochthonous product made of sheep milk, on the territory of Sjenica-Pester Plateau. Pirot kachkaval is firm cheese of steamed curdle produced from mix of sheep and cow milk (1:2 ratio) on the territory of Stara Planina Mountain. These are geographical areas where production takes place in village households/farms and on mountains in summer cottages (katun, bacija), which is characteristic of craft dairy processing. Specific traits of traditional manufacturing of Sjenica cheese and Pirot kachkaval derive from climatic conditions, characteristic grass associations of the specific mountain region and milk from autochthonous populations (Sjenica and Pirot sheep). In order to maintain the traditional manufacturing technology of these native products and to have organized production, it is necessary to protect the geographical origin of these products.

AB  - In order to have a more precise description of dairy farm structure and characteristics of dairy production systems, as well as to assess possibilities for improving production and farming conditions in which milk production is organized, a survey based research was directed at a select group of farms across the Serbia. 1180 questionnaires have been mailed to farmers whose farms are registered for either cattle or mixed production. Questionnaire was divided into 6 sections: general information of the farm, agricultural and structural information, zootechnical information, sanitary and veterinarian information, information about education and extension, and information on the perspectives of future farming. About 59% of analyzed farms have size up to 20 ha, with average size of about 10 ha. On the other hand, about 55% farms raises up to 15 cows and heifers with average of 6 heads per farm, while 3% of farms have more than 200 cows and heifers. Over 86% of surveyed farmers intend to expand existing farm production, mainly by increasing the number of animals, stricter selection and improvement of the conditions for feeding, housing, care and milking. About 75% of farmers have expressed a positive expectation from future membership of Serbia in EU, although these expectations are not clearly defined.
AB  - U cilju preciznijeg opisa strukture mlečnih farmi i karakteristika sistema za proizvodnju mleka, kao i procene mogućnosti za unapređenje proizvodnje i farmskih uslova u kojima se proizvodnja mleka organizuje, sprovedena je anketa među poljoprivrednim proizvođačima (farmerima) širom Srbije. Ukupno je poslato 1180 anketa farmerima čije su farme registrovane za govedarsku ili mešovitu proizvodnju. Upitnik koji je poslat farmerima sastojao se iz 6 delova i obuhvatao je opšte informacije o farmi, poljoprivredne i strukturne informacije, zootehničke informacije, sanitarne i veterinarske aspekte proizvodnje, edukaciju i savetodavstvo, kao i perspektive budućeg poslovanja. Oko 59% analiziranih farmi ima veličinu do 20ha, sa prosekom od oko 10ha. Sa druge strane, na oko 55% farmi odgaja se do 15 krava i junica, sa prosekom od 6 grla po farmi. Preko 86% anketiranih farmera namerava da proširi postojeću proizvodnju i to uglavnom povećanjem broja životinja, strožijom selekcijom roditeljskih parova, kao i unapređenjem uslova ishrane, smeštaja i nege. Oko 75% anketiranih farmera izrazilo je pozitivna očekivanja od budućeg članstva Srbije u EU, iako ta očekivanja nisu uvek jasna ili precizno definisana.

AB  - Cattle production in Serbia, and especially milk production, contributes significantly to the value of total agricultural production (20%) and livestock production (45%). Achieved annual rate of milk yield increase of approx.100 kg per cow cannot adequately compensate for drastic decrease of number of dairy cattle which dropped by fifth over last decade. This is especially important from the aspect of assessment of future production quotas for milk as part of Serbia's preparation for EU accession. From the aspect of the genetic potential of dairy cattle, the most significant measure aimed at increase of milk performance in future will be execution of systematic selection-breeding work in the main population. Special attention should be directed in future to selection of parents of dairy herd, criteria for selection of heifers and their adequate rearing in sense of nutrition and housing. For the purpose of establishing of production potential of first calving Simmental cows in Serbia, data was analyzed for 37.171 Simmental cows with completed lactations in the period 2007 to 2010. Research results showed moderate trend of increase in milk performance in first calving cows - average milk production of 4.348 kg, milk fat content of 3.93% and milk fat yield of 171.1 kg. Milk performance of first calving cows in average was lower by 147 kg compared to cows in other lactations and by 1.169 kg compared to bull dams in the observed period. In analysis of bulls - most common sires of studied first-calvers, it was established that eight of ten bull sires had negative values for milk yield, which indicated the need for better cooperation and organization in work of all services which are included in selection-breeding activities in dairy cattle breeding.
AB  - Govedarstvo Srbije a posebno proizvodnja mleka značajno učestvuju u vrednosti ukupne poljoprivredne (20%) i stočarske proizvodnje (45%). Postignutim tempom rasta prinosa mleka od oko 100 kg po kravi godišnje ne može se adekvatno kompenzovati drastičan pad broja mlečnih grla koji je u protekloj deceniji opao za petinu. Ovo je posebno značajno sa aspekta procena budućih proizvodnih kvota za mleko u priprema Srbije za ulazak u EU. Sa aspekta genetskog potencijala mlečnih krava, najznačajnija mera za povećanja prinosa mleka u narednom periodu je sprovođenje sistematskog odgajivačko-selekcijskog rada u matičnoj populaciji. Izboru roditeljskih parova budućih generacija mlečnog stada, kriterijumima odabira junica i njihovom pravilnom odgoju u smislu ishrane i uslova držanja treba posvetiti primaran značaj. U cilju utvrđivanja proizvodnog potencijala prvotelki simentalske rase u Republici Srbiji analizirani su podaci 37.171 simentalskih krava koje su svoje prve laktacije zaključile u periodu od 2007-2010 godine. Rezultati istraživanja pokazali su umereni trend porasta mlečnosti prvotelki sa ostvarenom prosečnom proizvodnjom od 4.348 kg mleka, sadržajem od 3,93% i prinosom od 171,1 kg mlečne masti. Mlečnost prvotelki u proseku je bila niža za 147 kg od mlečnosti krava u ostalim laktacijama i za 1.169 kg od mlečnosti bikovskih majki u posmatranom periodu. Analizom bikova - najčešćih očeva ispitivanih prvotelki, utvrđeno je da je osam od deset bikova-očeva imalo negativne vrednosti za prinos mleka što upućuje na neophodnost bolje saradnje i organizacije u radu svih službi koje obavljaju odgajivačko-selekcijski rad u mlečnom govedarstvu.
