AB  - The investigation was performed on two groups of primiparous and multiparous healthy dewormed Alpine dairy goats (25 each) during peripartal period. Blood samples were collected (jugular venipuncture) 10-15 days before and 10-15 and 30 days after the parturition into BD SST-II Advance (3.5 mL) and BD NaF 3.0 mg Na2EDTA 6.0 mg (2 mL) vacutainers, cooled and
centrifuged (1500 r/min, 15 minutes and ≤1300 r/min, 10 minutes, respectively). Glucose, non-esterified fatty acids (NEFA) and β-hydroxybutyrate (BHBA) concentrations in blood sera were determined using A15 automatic spectrophotometric analyzer (Biosystem, Spain). Simultaneously, body condition scoring (BCS) was performed by Villaquiran et al. (2007) method. The obtained data were analyzed by IBM SPSS statistics 21. The glucose concentration inclined to increase in both groups. Differences between glucose levels were significant (P<0.05) 15 days before and 15 days after, as well as 15 and 30 days after the parturition, and very significant (P<0.01) 15 days before and 30 days after the parturition. The BHBA blood levels significantly differed 15 days before and 30 days after and 15 and 30 days after the parturition (P<0.05). BHBA concentration peaked at week 2 postpartum, following the increase of NEFA, providing the substrate for BHBA synthesis. NEFA levels significantly (P<0.05) differed 15 days before and 15 days after the parturition. Goats’ BCS ranged from 2 to 4 and significantly depended on glucose (r=0.392; P<0.05) and BHBA (r=0.317; P<0.05) level 15 days before parturition. BCS 30 days postpartum very significantly depended on the glucose level (r=0.450; P<0.01), significantly higher than the concentration of BHBA (r=0.351; P<0.05) and NEFA concentration (r=-0.304; P<0.05). BCS 15 days before parturition did not depend on the NEFA concentration. Fifteen days after the parturition BCS did not statistically depend on the observed indicators. Obtained data suggest that knowledge of BCS and energy indicators levels may be very useful in research and practice in order to appreciate energy metabolism of pregnant and lactating dairy ruminants, particularly dairy goats. These data are poorly documented for goats, but they can reveal early pathological metabolic changes in transiting female goat organism, enabling successful prophylactic, as well as, therapeutic intervention.

AB  - The objective of this research paper was to estimate heritability coefficients (heritability) of growth traits in the lambs of indigenous Sjenicka Pramenka breed. The research was conducted on a sample which included 421 lambs the descendants of 15 sires and 187 sheep-dams, raised on 3 private farms in Kolubarski district, Serbia. The effect of fixed factors was studied while the values of heritability coefficients were estimated within the frame of SAS software package. A statistically highly significant (**=P<0.01) effect on studied traits had following parameters: sex, year of lambing, type of lambing, farm and method of applied reproductive technology. By means of REML method and using the sire model the values of heritability coefficients were determined for the following traits: average lamb birth weight (BW0), average lamb body weight at 30 days (BW30) and average lamb body weight at 90 days (BW90) being: 0.0355; 0.4642 and 0.3018, respectively.

AB  - The aim of this study was to investigate changes of serum testosterone, scrotal circumference, body weight, and semen characteristics in a Meat Institute Sheep (MIS) population during their developing period (between 3 and 17 months). Correlative relationships among parameters were also tested. Body weight and scrotal circumference were measured monthly, blood samples for testosterone levels were taken bimonthly (3-17 months), and semen samples were collected by an electroejaculator between the ages of 9 and 17 months. The analysis showed that the average serum testosterone levels ranged from 1.83 to 13.28 ng/mL and significantly depended on the age of the lambs (P  (lt)  0.05). The trend in the level of serum testosterone was characterized by pronounced variability throughout the study period. Changes in scrotal circumference and body weight were significantly dependent on age. Ejaculate volume, sperm motility, and the percentage of live spermatozoa increased with age, except for the percentage of abnormal spermatozoa, which decreased with age. Correlations among serum testosterone, scrotal circumference, and body weight were moderately to highly positive and highly significant. All parameters of semen quality were poorly correlated with testosterone and body weight, while scrotal circumference was in moderate correlation only with ejaculate volume and live sperm count (P  (lt)  0.05).

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.

U Srbiji bivoli se gaje u području Raške oblasti (oko 1000 bivola) i na području Kosova. Populacija bivola u centralnoj Srbiji ima tendenciju smanjenja veličine, zbog čega je pre 10 godina počeo da se sprovodi program konzervacije. Na uzorku populacije (37 bivolica) obuhvaćene programom in situ konzervacije utvrđene su prosečne vrednosti za telesne mere. Visina grebena bivolica u populaciji koja je merena bila je 125,97 cm, visina krsta 126,98cm, dužina trupa 142,19cm, dubina grudi 68,75 cm, širina grudi 44,48cm, a obim grudi 184,25 cm. Populacija bivolica je bila dosta neujednačena što ukazuje na odsustvo odgajivačko-selekcijskog rada kod bivola u Srbiji u prethodnim decenijama.

AB  - This study was conducted in five dairy farms with different capacity (farms A with 47, B 12, C 10, D 14 and E 24 Simmental cows, aged between 4 and 5 years and body weight about 600 kg) in order to determine a relationship between rearing system, Animal Needs Index (ANI) and milk traits. Loose system of cow rearing was used in open stalls in farms A and C, while in other farms cows were tied in closed stalls. In two farms, there were outdoor pens, permanently available to cows on farm A, and during daytime on farm D. Rations for dairy cows were equal in all five farms and suitable for daily milk production about 20 kg with 4.0 % milk fat and 3.5 % milk protein. It was established that total ANI scores for farms were A 35.5, B 9.5, C 24.5, D 26.5 and E 10.5. The welfare levels in farms B and E were not sufficient, in farms C and D were very good, while in farm A it was excellent. A very significant influence of rearing system on cow welfare was found (p (lt) 0.001). A significant influence of rearing system (p (lt) 0.01) on average daily milk yield, milk yield in standard lactation, milk fat (kg), yield of 4 % fat corrected milk and yield of proteins (kg) were noticed. The influence of the rearing system on milk fat content (%), dry matter (%), protein (%) and lactose (%) was not statistically significant. Differences between ANI score, daily and standard lactation milk yield were very significant (p (lt) 0.001), as well as differences between ANI and the amount of milk fat (kg), protein (kg) and amount of 4 % fat corrected milk.

The welfare levels in farms B and E were not sufficient, in farms C and D were very good, while in farm A it was excellent. A very significant influence of rearing system on cow welfare was found (p (lt) 0.001). A significant influence of rearing system (p (lt) 0.01) on average daily milk yield, milk yield in standard lactation, milk fat (kg), yield of 4 % fat corrected milk and yield of proteins (kg) were noticed. The influence of the rearing system on milk fat content (%), dry matter (%), protein (%) and lactose (%) was not statistically significant. Differences between ANI score, daily and standard lactation milk yield were very significant (p (lt) 0.001), as well as differences between ANI and the amount of milk fat (kg), protein (kg) and amount of 4 % fat corrected milk.",

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.

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  - The most significant welfare problems in dairy calves in intensive rearing conditions have been investigated in this paper. These problems mainly result from inadequate intake of colostrum (separation from the dam), inadequate ventilation (resulting in inappropriate airflow, low or high temperatures, high humidity and poor air quality), poor floor conditions (wet floor, without bedding), inadequate monitoring of health, exposure to pathogens causing respiratory and gastrointestinal disorders and occurrence of iron deficiency. In addition, on cattle farms in our country welfare problems in calves originate from continuous restocking (no 'all in - all out') and mixing calves from different sources, as well as insufficiently balanced solid food, insufficient access to water and generally poor response of farmer to health problems, especially necessary dietary changes. A special welfare problem is insufficient floor space allowance which results in calf's discomfort.
AB  - U radu su istraženi najznačajniji problemi dobrobiti kod teladi u intenzivnim uslovima gajenja.

AB  - For the purpose of realization of the project of development of sustainable sheep production systems, in this paper, the major influences on production parameters of sheep in conditions of Stara Planina Mountain are investigated. Using the knowledge of gene effects, with good breeding programs, it is possible to realize, with more or less success, planned annual genetic progress of traits which are of interest to the breeders. This relates first of all on gain of lambs and milk yield in sheep. As already known, traits of body development and milk production vary depending on the factors of hereditary nature, but also factors of the environment. Therefore, the level of application of selection-breeding criteria is of great practical importance, which is confirmed also in this paper, and level of significance was statistically confirmed. Also, for complete creation of the program of improvement of sheep milk and meat production it is important to be aware of the effect of the breed itself, as well as of type of birth on production parameters, which was taken into consideration during investigation, processing and presentation of data in this paper. Obtained results show that majority of observed factors had significant effect on realized production of sheep.
AB  - Za razvoj održive ovčarske proizvodnje, između ostalog, neophodna je primena visokih kriterijuma selekcije i odgajivanja. Cilj ovog rada je da ukaže na praktičan značaj nivoa primene kriterijuma selekcije i odgajivanja u proizvodnji mesa i mleka ovaca u ekstenzivnom sistemu gajenja na Staroj planini. Proizvodnja mesa i mleka ovaca na Staroj planini je tradicionalna i istorijski posmatrano, uglavnom je zasnovana na gajenju pirotske pramenke, kao lokalne populacije u ekstenzivnim proizvodnim sistemima. Ova rasa kao i većina lokalnih populacija poseduje solidan genetski potencijal za prirast jagnjadi i mlečnost ovaca, ali da bi se taj potencijal ispoljio, potrebna je primena viših kriterijuma selekcije i odgajivanja, što uglavnom nije slučaj. Pored pramenke od druge polovine XX veka na području pirotskog dela Stare planine uvedena je u primenu i nova populacija-pirotska oplemenjena ovca. Ona se takođe u većini slučajeva gaji kao i pirotska pramenka, mada ove dve rase u genetskom smislu imaju veoma malo zajedničkog. Kao što je poznato, osobine telesnog razvoja i mlečnosti ovaca variraju u zavisnosti od mnogih faktora nasledne prirode ali i različitih spoljnih uticaja.

AB  - In this paper, fertility parameters of sheep are discussed and principles analyzed in order to obtain the optimal methods for their evaluation. Mathematical procedures for evaluation of genetic and phenotypic parameters and anticipation of genetic values, today, are mainly based on different linear and non-linear concepts, therefore it is necessary to accept the reality that there is no absolute accuracy. Special emphasis is on the possibility of use of physiological quantitative fertility indicators in sheep selection, considering that there is correlation between them and fertility traits.

abstract = "In this paper, fertility parameters of sheep are discussed and principles analyzed in order to obtain the optimal methods for their evaluation. Mathematical procedures for evaluation of genetic and phenotypic parameters and anticipation of genetic values, today, are mainly based on different linear and non-linear concepts, therefore it is necessary to accept the reality that there is no absolute accuracy. Special emphasis is on the possibility of use of physiological quantitative fertility indicators in sheep selection, considering that there is correlation between them and fertility traits. In this regard, the degree of response to direct and indirect selection within population is analyzed in order to established the nature of parameters necessary for evaluation of data and determine the relative degree of such response., U radu se razmatraju parametri plodnosti ovaca i analiziraju principi iznalaženja optimalnih metoda za njihovu procenu.

AB  - The production of milk in a sheep breed households was 128.05 kg, with variations between 123.14 and 138.63 kg. Period of lactation was 165.04 days. Content of milk fat was 6.53%. There were significant differences in dependence of farms. Maximal daily production was in the first month of lactation. Milk yield was 1.046 kg. From the beginning till the end of lactation, milk yield was reduced for 0.479 kg, so at the end the yield was 0.567 kg. Content of milk fat at the first control was 5.30%, at the second, 6.23%, at the third, 6.98% and at the fourth control it was 7.62%. The influence was very significant on the daily production of milk.
AB  - U ovom radu prikazani su rezultati kontrole mlečnosti kod ovaca svrljiške pramenke. Istraživanje je obavljeno na šest gazdinstava i ukupno je kontrolisano 130 grla. Na osnovu dobijenih rezultata utvrđeno je trajanje laktacionog perioda od 165,04 dana. Količina proizvedenog mleka prosečno je iznosila 128,05 kg, u kojem je bilo 6,53% mlečne masti. Podaci pokazuju da postoji vrlo značajna statistička razlika (P  (lt) 0,01) u prinosu mleka između ovaca na gazdinstvu III u odnosu na II gazdinsitvo. Razlika je iznosila 15,49 kg ili 12,58%. Razlike između gazdinstava III > IV od 10,30 kg (8,03%); III > II od 9,86 kg (7,66%) bile su takođe statistički vrlo značajne (P  (lt) 0,01). Prosečna dnevna mlečnost se smanjivala od prve do četvrte kontrole, tj. laktacija je imala stalni descendentni tok. Količina dnevne mlečnosti 30-tog dana laktacije tj. kod prve kontrole prosečno je iznosila 1,046 kg, druge kontrole 0,878 kg, treće 0,736 kg i četvrte 0,567 kg. Sadržaj mlečne masti u mleku se povećava od prve do četvrte kontrole. Vrednosti su bile 5,30% mlečne masti kod prve, 6,23% druge, 6,98% treće i 7,62% četvrte kontrole. Gazdinstvo tj. farma je imala značajan uticaj na ukupnu količinu namuženog mleka.

AB  - Considering that total variability of milk traits in sheep within single population greatly depends on factors of genetic nature, objective of this paper was to investigate the trend of genetics parameters in populations raised in Pirot region, in order to create more efficient selection program in regard to milk production. Obtained and processed results of investigation have demonstrated that investigated traits occupy central heritability values. Degree of heritability for protein and fat had higher values in relation to other observed traits. Weak and negative genetic correlation is present between fat content and other traits whereas strong and positive correlation was determined for milk quantity and fat content and protein. Statistical analysis confirmed absence of significant differences between sheep of Pirot Pramenka breed and improved Pirot population. This research has also demonstrated that in selection of sheep in regard to milk traits and production special attention should be directed to importance of genetic parameters considering that with the increase of quantity of milk not only content of fat but also of protein are reduced, which can influence the economical efficiency on farm in system of payments for milk according to its quality.

AB  - Project research includes investigation of environmental conditions in which sheep are raised, also breed structure in region of Stara planina mountain and genetic potential of sheep population for production of high quality lamb meat. Heterosis effect is also investigated, and new created genotypes, beside improved performance in regard to gain, feed conversion and dressing percentage, will have as consequence improvement of the quality and quantity of carcass and meat of lambs. New created genotypes can be successfully raised in hilly, hilly-mountainous and plain regions. Existing technological solutions in regard to housing of sheep and lambs will be innovated by introduction of several variants and systems of nutrition which would include maximum use of roughage - pasture, hey and silage for grown heads of livestock, with addition of adequate quantities of concentrated feeds, also solutions introducing the highest degree of rationalization in production of high quality lamb meat will be selected. Floral composition and nutritive value of grass mass at our disposal as well as grain feeds are to be analyzed. Based on forage plant base at our disposal and quality of feeds the concrete programme of nutrition of lambs according to fattening phase will be applied. During fattening, effect on nutrition on production performance (gain of body mass and feed conversion) will be monitored. Reproductive traits of sheep - dams and ram sires will be analyzed, also planned health protection of animals carried out. Also economical efficiency of organized lamb breeding for production of high quality lamb meat analyzed. Most favorable anatomical categories for packaging will be determined as well as physical, chemical and sensory parameters of the quality of lamb meat defined. Special attention will be directed towards the quantity and quality of obtained lamb carcasses and compared with EU standards.

AB  - Certain reproductive and performance traits of Simmental cows, as well as the demonstration of those traits depending on the effect of age at first fertilization, were investigated. The investigation included 606 cows divided according to age at first fertilization, in 10 groups (one month difference among groups). Statistical analysis of data was done by method of Least squares (LSMLMW, Harvey, 1987), the model with fixed influence of factors on observed traits was applied. In regard to the demonstration of performance traits, the effect of age at first fertilization was most expressive in first lactation. The greatest negative deviation from the general average in milk yield and yield of milk fat, were established in first calving cows which were the youngest at fertilization-calving. The increase of age at first fertilization induced the less negative deviations from the general average. In the second and third lactation, deviation from the general average depending on the age at first fertilization, expressed the same trend, but within the limits of random deviations (PX),05).
AB  - Ispitivane su proizvodne osobine krava simentalske rase i njihova ispoljenost u zavisnosti od uzrasta pri prvoj oplodnji. Dobijeni rezultati su pokazali da je uzrast grla pri prvoj oplodnji visoko-značajno (P (lt) 0,01) na proizvodnju mleka i mlečne masti u prvoj laktaciji. U drugoj i trećoj laktaciji ispoljenost proizvodnih osobina nije značajno zavisila od uzrasta pri prvoj oplodnji.

AB  - The investigation was carried out on the sheep farm on the mountain Stara planina. The trial included two sheep genotypes: 1. Pirot pramenka sheep and 2. Improved Pirot sheep. In order to estimate necessary parameters the least squares method was used. The obtained results show that heritability of milk yield was 0.35 and 0.33, fat percent amounted to 0.49 and 0.44, while protein percent was 0.50 and 0.49 (in the 1st and 2nd genotype, respectively). Results on the genetic correlation between important parameters of milk showed that there were both, positive and negative correlations. Coefficient estimations of genetic correlations of certain traits varied from very weak to strong. Correlations between fat yield and milk yield were 0.87 and 0.88, but the coefficient between protein percent and fat yield was -0.01 and -0.04, in the 1st i.e. 2nd genotype, respectively. There are no significant differences between observed genotypes.
AB  - ispitivanje genetičkih parametara (heritabilnosti i genetičkih korelacija) osobina mlečnosti ovaca je bilo cilj rada. Ispitivanja su obavljena na jednoj farmi ovaca u regionu Stare planine, kod dva genotipa (pirotska pramenka i pirotska oplemenjena ovca). Heritabilnost varira u granicama srednjih vrednosti sa maksimumom kod sadržaja proteina. Ustanovljena je kako, pozitivna, tako i negativna genetička korelacija posmatranih osobina mlečnosti ovaca. Vrednosti koeficijenata se kreću od slabih do jakih, a nisu utvrđene značajne razlike između genotipova.
