AB  - Gene expression at the phenotypic level varies due to a number
of influences from the environment in which the animals are reared. Ignoring this
reality or due to insufficient knowledge, farmers are often disappointed when
choosing a population of sheep when they do not get the production results that the
breed achieves where they bought it. The investigation of the reproductive and
production characteristics of parent herds of Sjenica sheep was conducted on four
farms. In the research, it included a total of 921 lambs and 474 sheep. The
influence of sheep body weight on the weight of lambs at birth within a farm was
analyzed. Based on the research conducted on the sheep population and after the
obtained and processed data, we can state the following: certain differences were
found in the fertility of sheep depending on the farm and body weight. We also
perceived that certain differences in the body weight of the lambs are evident
depending on the weight group of the sheep and the farm where the sheep were
raised. All of the above leads us to the general conclusion that management is
extremely important in sheep farming. If the selection of the breeding population is
carried out correctly and adequate measures of keeping, nutrition and reproduction
are applied, success is guaranteed.

AB  - Climate change poses a major global concern and is therefore an
ongoing topic. World’s population is expected to reach 9.7 billion people by 2050
and 10.4 billion by 2100, which means that the food resources will become crucial.
In that respect, animal protein is considered a vital nutrient for growing human
population. However, in the light of ever-changing climate events food and water
sources for both animals and humans can become scarce in certain areas. The
impacts of higher temperatures, changes in precipitation and extreme weather
events pose the most risk on agricultural systems such as livestock. Direct and
indirect influence of heat and drought caused by global warming is harmful to
livestock. Small ruminants and particularly goats are considered more resilient and
better adapted to hot and dry environments compared to other livestock. These
animals require less in terms of feed, water and labor than large ruminants and are
also more thermo-tolerant. They have certain physiological, behavioral and
anatomical advantages aiding their survival during heat and drought. Goats are less
of a competition to humans in terms of available food as they can thrive on plants
unusable for human nutrition. The review discusses advantages of goats as species
in terms of adaptation to changing climate.

AB  - During study of gastrointestinal helminths of small ruminants in Serbia, performed from
2010 to 2020 we collected fecal samples from 470 herds in various part of Serbia.
Samples were colected at monthly intervals and we examined more than 6500 faecal
samples. Examination was performed using standard coprological technique. During ten
years 738 sheep and goats we were examined by post-mortem examination.
Determination of adult parasites and eggs of parasites were done by morphological
characteristic. During these investigations, the following GI helminths were found in
sheep:: Haemonchus contortus, Teladorsagia (Ostertagia) circumcincta, Ostertagia
trifurcata, Ostertagia ostertagi, Ostertagia occidentalis, Marshallagia marshalli,
Trichostrongylus axei, Trichostrongylus colubriformis, Trichostrongylus vitrinus,
Nematodirus filicoliis, Nematodirus spathiger, Nematodirus abnormalis, Cooperia
curticei, Cooperia oncophora, Cooperia punctata, Cooperia zurnabada, Skrjabinema
ovis, Bunostomum trigonocephalum, Oesophagostomum venulosum and Chabertia
ovina. In goats, the presence has been establishedOstertagia circumcincta, O. ostertagi,

Skrjabinema ovis, Bunostomum trigonocephalum, Chabertia ovina, Oesophagostomum
venulosum i Cooperia curticei. The intensity of infection and polyparasitsm was
monitored in relation to the age of sheep and goats. It was found that in younger animals
intensity of infection was lower than that of older animals.
The dynamics of the first appearance of established gastrointestinal strongylid species in both
populations of small ruminants was as follows: in March in sheep faeces we have occurred eggs of
Ostertagia sp., Trichostrongylus sp. and Nematodirus sp.. In May, were observed infection withBunostomum sp. and Chabertia spp. (ovina);. During June we had first record of Skrjabinema sp.. In
Modern Trends in Agricultural Production, Rural Development, Agro-economy, Cooperatives and Environmental ProtectionJuly were established eggs of Haemonchus sp. (contortus) and Cooperia sp. finally, in October and

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  - Several factors have led to a decline in autochthonous breeds, and the need for conservation programs based on risk assessment has increased. The aim of the study was to compare and validate two models for risk assessment of local small ruminant breeds in Serbia. The first model considered only the effective population size (Ne), while the alternative model included Ne, the number of females and sub-factors representing the influence of different elements. The results indicate an increasing trend in most breeds and populations over the last five years, with the exception of Tsigai and Chokan Tsigai, which showed a decrease. However, the increasing trend is insufficient, especially for Pirot, Karakachan, and Bardoka, as well as for the Domestic (Serbian) white goat, which is classified as critically endangered in both models. Vlashko vitoroga, Chokan tsigai, and the Balkan goat were at high risk. The models produced different results for the Krivovir, Sjenica, and Svrljig strains. In the first model, Krivovir was classified as potentially endangered, whereas Sjenica and Svrljig were not. In the second model, Krivovir was classified as highly and the other two strains as potentially endangered. These differences are due to the additional factors in the second model, which lead to a more comprehensive assessment for future risk assessments. Although the new model is appropriate for Serbia, it is important to test it on a variety of native species to increase confidence. Future conservation programs should also include genetic characterization and implement adaptive models to obtain more reliable conclusions.
AB  - Genetički resursi poseduju urođenu genetičku varijabilnost, prilagodljivi su različitim okruženjima i pokazuju različite fizičke, fiziološke i produktivne osobine. Ipak, različiti faktori doveli su do opadanja veličine populacija autohtonih rasa zbog konkurencije uvoznih rasa, što je rezultiralo potrebom za programima konzervacije zasnovanim na proceni ugroženosti rasa. Cilj studije je bio poređenje i validacija rezultata dva modela evaluacije za procenu rizika ugroženosti autohtonih rasa malih preživara u Srbiji. Prvi model je razmatrao samo efektivnu veličinu populacije (Ne), dok je alternativni model uključivao Ne, broj ženki i podfaktore koji predstavljaju uticaj različitih elemenata. Rezultati ukazuju na trend povećanja brojnosti kod većine rasa i populacija u poslednjih pet godina, osim kod cigaje i čokanske cigaje, čija je brojnost opadala. Međutim, porast brojnosti kod ostalih genotipova nije dovoljan ni zadovoljavajući, posebno kod pirotskog, karakačanskog i bardoka soja ovaca, kao i kod domaće (srpske) bele koze, koje su klasifikovane kao kritično ugrožene u oba modela. Vlaško vitoroga, čokanska cigaja i balkanska koza ocenjene su kao visoko ugrožene u svom opstanku. Korišćenjem modela dobijeni su različiti rezultati za krivovirski, sjenički i svrljški soj. U prvom modelu, krivovirski je ocenjen kao potencijalno ugrožen, dok sjenički i svrljiški nisu bili ugroženi. Međutim, u drugom modelu, krivovirski soj je označen kao visoko ugrožen, a druga dva soja kao potencijalno ugroženi.

abstract = "Several factors have led to a decline in autochthonous breeds, and the need for conservation programs based on risk assessment has increased. The aim of the study was to compare and validate two models for risk assessment of local small ruminant breeds in Serbia. The first model considered only the effective population size (Ne), while the alternative model included Ne, the number of females and sub-factors representing the influence of different elements. The results indicate an increasing trend in most breeds and populations over the last five years, with the exception of Tsigai and Chokan Tsigai, which showed a decrease. However, the increasing trend is insufficient, especially for Pirot, Karakachan, and Bardoka, as well as for the Domestic (Serbian) white goat, which is classified as critically endangered in both models. Vlashko vitoroga, Chokan tsigai, and the Balkan goat were at high risk. The models produced different results for the Krivovir, Sjenica, and Svrljig strains. In the first model, Krivovir was classified as potentially endangered, whereas Sjenica and Svrljig were not. In the second model, Krivovir was classified as highly and the other two strains as potentially endangered. These differences are due to the additional factors in the second model, which lead to a more comprehensive assessment for future risk assessments. Although the new model is appropriate for Serbia, it is important to test it on a variety of native species to increase confidence. Future conservation programs should also include genetic characterization and implement adaptive models to obtain more reliable conclusions., Genetički resursi poseduju urođenu genetičku varijabilnost, prilagodljivi su različitim okruženjima i pokazuju različite fizičke, fiziološke i produktivne osobine. Ipak, različiti faktori doveli su do opadanja veličine populacija autohtonih rasa zbog konkurencije uvoznih rasa, što je rezultiralo potrebom za programima konzervacije zasnovanim na proceni ugroženosti rasa. Cilj studije je bio poređenje i validacija rezultata dva modela evaluacije za procenu rizika ugroženosti autohtonih rasa malih preživara u Srbiji. Prvi model je razmatrao samo efektivnu veličinu populacije (Ne), dok je alternativni model uključivao Ne, broj ženki i podfaktore koji predstavljaju uticaj različitih elemenata. Rezultati ukazuju na trend povećanja brojnosti kod većine rasa i populacija u poslednjih pet godina, osim kod cigaje i čokanske cigaje, čija je brojnost opadala. Međutim, porast brojnosti kod ostalih genotipova nije dovoljan ni zadovoljavajući, posebno kod pirotskog, karakačanskog i bardoka soja ovaca, kao i kod domaće (srpske) bele koze, koje su klasifikovane kao kritično ugrožene u oba modela. Vlaško vitoroga, čokanska cigaja i balkanska koza ocenjene su kao visoko ugrožene u svom opstanku. Korišćenjem modela dobijeni su različiti rezultati za krivovirski, sjenički i svrljški soj. U prvom modelu, krivovirski je ocenjen kao potencijalno ugrožen, dok sjenički i svrljiški nisu bili ugroženi. Međutim, u drugom modelu, krivovirski soj je označen kao visoko ugrožen, a druga dva soja kao potencijalno ugroženi. Ove razlike su posledica dodatnih faktora u drugom modelu, što je dovelo do sveobuhvatnije i adekvatnije procene za ocenjivanje statusa ugroženosti. Iako primenljiv u našim uslovima, da bi mu se povećala pouzdanost, novi model treba testirati na različitim vrstama domaćih životinja. Takođe, programi zaštite moraju uključiti genetičku karakterizaciju i primeniti prilagodljive modele za pouzdanije zaključke.",

AB  - This study investigated the possibility of using morphometric measurements to differentiate the autochthonous Serbian White goat breed from Saanen and Balkan goats, which were used as sire and dam breeds in its creation. For this purpose, a multivariate discriminant analysis was used. A total of 11 morphometric traits were measured in 98 does of 3 breeds: Saanen (n = 28), Balkan (n = 28), and Serbian White (n = 42), aged 2 to 7 years, in 4 different locations. Univariate analysis of variance revealed a significant difference in body measurements of all three breeds, with Saanen goat being the largest in format and Balkan the smallest. Discriminant analysis extracted six out of eleven tested morphometric traits with the strongest discriminatory power: heart girth, head length, chest depth, head width, pelvic width, and body length. Mahalanobis distances were significant between all three genetic groups. The discriminant function correctly classified 95.24% of the Domestic White goats investigated to their source group. The classification accuracy of the function was cross-validated and indicated an overall success rate of 91.84%. The results of this research showed that there was a clear separation between Serbian White, Saanen, and Balkan goats. The present findings could help a more rapid field assessment of Serbian White goats.

AB  - Meat colour was evaluated in 36 goat kids of both genders equally from three breeds: Alpine, Balkan and Serbian white breed. Animals were slaughtered at 18 kg of body weight and three muscles were analysed for colour characteristics and pH value: m. longissimus lumborum, m. psoas major (tenderloin) and m. semimembranosus. pH values differ significantly only for m. longissimus lumborum muscle, whereas Balkan kids had a significantly higher pH value than Alpine and Serbian white (p<0.001). The goat breed significantly affected meat CIEL*a*b* values for all muscles analysed. Lightness (L*) was generally the highest for Balkan and lowest for the Alpine breed. The differences in redness (a*) and Chroma values (C*) were not significant, while the yellowness only differed for m. longissimus lumborum muscle, whereas Serbian white kids had higher b* values compared to Alpine kids. As a colour saturation characteristic, the hue angle was higher in meat from indigenous breeds (Balkan and Serbian white) than in the Alpine breed.

AB  - The research included a total of 921 lambs, 474 ewes and 8
sjenicke sheep rams from 4 different farms. The aim of the research was to
examine the influence of the farm, cultivation technology and the influence of rams
within the farm on production indicators. Statistical analysis showed that the body
weight of lambs at birth ranged from 3.37 to 4.03 kg (average 3.68 kg), at 30 days
from 11.51 to 12.41 kg (average 12.07 kg) and from 90 days from 27.82 to 29 kg
(average 28.65 kg). A statistically highly significant influence of the farm was
determined (P<0.01) on the body weight of lambs in all three control periods, as
well as on the body weight of sheep and on the fertility of sheep. The influence of
the ram on the body weight of the lambs at birth was statistically very significant
within the farm (P<0.01). When it comes to the percentage share of birth type by
farm, farm 1 had the most singletons (59.13%) both within the farm and in
comparison between other farms, while there were fewer twins (40.87%), and
triplets were not identified. On the other farms, the percentage of twins was the
highest, and triplets were also present, while on farm 4 there were also quadruplets,
lambs born as quadruplets (3.28%).

AB  - Lipska sheep is an autochthonous Serbian population from the
group of Pramenka (Zapfel) sheep, bred in the area around Smederevo, Požarevac
and Mladenovac. The average weight of male animals (BW) is 95 kg and 62 kg of
female animals. Other measurements of female animals are: wither height (WH) 74
cm, body length (BL) 78 cm, chest width (CW) 23 cm, chest depth (CD) 40 cm and
hearth girth (HG) 91 cm. In the last sixty years, adult female animals gained in
average ten kilograms of weight. Other linear measures also increased. The
increase is a consequence of better animal management, especially improved diet.
Since the reduction of the size of the population, larger animals have dominated,
which probably caused the change in the genetic constitution of the breed. Female
animals of Lipska sheep are higher compared to the animals of other fifteen
Pramenka breeds with the exception of Istrian sheep. The area from which Lipska
sheep originates has better soil and richer vegetation compared to the areas of other
Pramenka breeds. Partial correlations corrected for weight between individual
linear measures were positive, with values between 0.196 and 0.814. Most
correlations range between 0.30 and 0.55. Body measurements were studied with
ANOVA on females only. The effect of flock influenced all linear measures with
the exception of CW, whereas the age of animals had no effect on BL, CW and

abstract = "Lipska sheep is an autochthonous Serbian population from the
group of Pramenka (Zapfel) sheep, bred in the area around Smederevo, Požarevac
and Mladenovac. The average weight of male animals (BW) is 95 kg and 62 kg of
female animals. Other measurements of female animals are: wither height (WH) 74
cm, body length (BL) 78 cm, chest width (CW) 23 cm, chest depth (CD) 40 cm and
hearth girth (HG) 91 cm. In the last sixty years, adult female animals gained in
average ten kilograms of weight. Other linear measures also increased. The
increase is a consequence of better animal management, especially improved diet.
Since the reduction of the size of the population, larger animals have dominated,
which probably caused the change in the genetic constitution of the breed. Female
animals of Lipska sheep are higher compared to the animals of other fifteen
Pramenka breeds with the exception of Istrian sheep. The area from which Lipska
sheep originates has better soil and richer vegetation compared to the areas of other
Pramenka breeds. Partial correlations corrected for weight between individual
linear measures were positive, with values between 0.196 and 0.814. Most
correlations range between 0.30 and 0.55. Body measurements were studied with
ANOVA on females only. The effect of flock influenced all linear measures with
the exception of CW, whereas the age of animals had no effect on BL, CW and
CD. The increase of individual linear measures was 0.5 to 2.1 mm per kg of BW.
The increase of most body measurements from the first to the fifth year was
statistically significant (P<0.05)., Lipska ovca je autohtona populacija iz grupe pramenki (Zapfel) koja se gaji u

AB  - The aim of this study was to investigate the effects of chestnut tannins in metabolizable
protein deficiency, on dry matter (DM) intake, growth performance of finishing lambs,
feed efficiency and digestibility of nutrients. The study included 30 crossbred lambs,
blocked by body weight (BW) and divided into three groups, depending on the concentrations of added chestnut tannins in the rations (0, 10 and 20 g/kg DM for CON, 10T and
20T group, respectively). Rations were determined by BW and expected average daily
gain (ADG), with a deficiency in metabolizable protein of about 15%. All groups received
the same amount of daily feed. Dry matter intake, ADG and indicators of efficiency such
as the Kleiber ratio (KR) and protein efficiency ratio (PER) were estimated. The digestibility of the rations was determined in three collection periods. Dry matter intake did not differ among groups. Growth performances for the whole experiment were significantly better for the 20T group than CON (p < 0.05), while no differences were established for
group 10T. Group 20T achieved the highest ADG and total gain (228 g/day ± 27.8; 13.7 kg
± 1.7), with the best average conversion of dry matter (4.4 kg DM/kg BW), KR (15.6), and
PER (1.6). In all three collections, dry matter and crude protein digestibility was higher
for CON, while the digestibility of ether extract was higher for the 20T group than CON.
Based on these results, it can be concluded that a ration of chestnut tannins in the concentration of 20 g/kg DM, in conditions of protein deficiency, can have a positive effect on
lamb performances. This can be partially explained by the ability of tannins to form complexes with proteins, which can change intestinal protein flow and utilization.
AB  - Das Ziel dieser Studie war, die Wirkungen von Kastanien-Tanninen in Rationen mit
unzureichender Versorgung mit metabolisierbarem Protein auf die Aufnahme von
Trockenmasse (DM), die Wachstumsleistung von Mastlämmern, den Futteraufwand und die Verdaulichkeit von Nährstoffen zu untersuchen. Die Studie umfasste 30 Kreuzungslämmer, die durch das Körpergewicht (BW) und die Konzentrationen von zugesetzten
Kastanien-Tanninen in der Nahrung (0, 10 und 20 g/kg DM für die Kontrolle, 10T- bzw.
20T-Gruppe) in drei Gruppen unterteilt wurden. Die Rationen wurden durch das Körpergewicht (BW) und die erwartete durchschnittliche tägliche Zunahme (ADG) mit einem
Mangel an metabolisierbarem Protein von etwa 15% definiert. Alle Gruppen erhielten
die gleichen Futtermengen. Die DM-Aufnahmen, ADG-Werte, und Verwertungsgrößen
wie das Kleiber-Verhältnis (KR) und das Protein-Effizienz-Verhältnis (PER) wurden
geschätzt. Die scheinbare Verdaulichkeit wurde in drei Sammelperioden ermittelt. Die
DM-Aufnahme unterschied sich nicht zwischen den Gruppen. Die Wachstumsleistungen
für das gesamte Experiment waren für die 20T-Gruppe signifikant besser als für die
Kontrollgruppe (p < 0,05), während für die 10T-Gruppe keine Unterschiede festgestellt
wurden. Gruppe 20T erreichte den höchsten ADG und Gesamtzuwachs (228 g/Tag
± 27,8; 13,7 kg ± 1,7) mit der besten durchschnittlichen Umwandlung von Trockenmasse
(4,4 kg DM/kg BW) und den günstigsten Werten für KR (15,6) und PER (1,6). In allen
drei Sammelperioden war die Verdaulichkeit von DM und Rohprotein bei der Kontrolle
höher, während die Verdaulichkeit des Rohfetts bei der 20T-Gruppe höher war als bei der
Kontrolle. Aus den Ergebnissen kann geschlossen werden, dass Kastanientannine in
einer Konzentration von 20 g/kg DM Futter bei Proteinmangel einen positiven Effekt auf
die Leistung von Mastlämmern haben können. Dies kann teilweise durch die Fähigkeit
von Tanninen erklärt werden, Komplexe mit Proteinen zu bilden, die den Proteinfluss
durch den Verdauungstrakt und seine Verwertung verändern können.

AB  - IGFBP-3 is responsible for the multiple effects of growth factors in most mammalian species and is considered the major transport factor of growth, used as a marker for different body functions such as growth, metabolism, reproduction, body weight control, immunity, energy balance, and so on. Considered as a candidate gene, used as a marker for the growth and production traits as its essential role in the growth and development of the animals. For the DNA extraction, the blood samples are obtained in the jugular vein using a 10 ml vacutainer containing EDTA as a coagulant in the blood collection of each animal Mis breed of sheep (M), Ile de France (F), and Wurttemberg (W). Isolation of DNA performed using the extraction kit (Quick DNA kit) with primers set the Forward and Reverse. The body weights of lambs from birth to 90 days of age, also been calculated. The results of the agarose gel electrophoresis of PCR amplified IGFBP-3 genes for sheep populations Wurttemberg (W), Mis (M), and Ile de France (F) had 654 bp. In our results showed an absence of polymorphism of the IGFBP-3 gene on the tested sheep populations. The results that there is no polymorphism between the examined sheep breeds, in terms of IGFBP-3 genes, we were interested whether there are differences in the body development of lambs of the mentioned populations because IGFBP-3 is related to the growth of animals. All three breeds have similar weights and growth dynamics, which could link to the growth hormone. Analyzing obtained results, we can suggest that absence of a large difference in the growth of the three breeds of sheep W, M, F does not have to be related to the absence of polymorphism of the IGFBP-3 gene but also other genetic and non-genetic factors can affect this trait. To detect the association between genetic polymorphism in IGFBP-3 genes and body development in lambs, DNA sequencing is required, which will be the subject of our future research.

AB  - During our research we examined flocks of small ruminant originated from 23 villages from city districts Mladenovac, Lazarevac, Obrenovac, Grocka, Zemun, Surčin, Palilula, Vozdovac and Zvezdara. In more than 80 percent of the herds, sheep and goats were breed together at same pasture. Using standard coprological methods we examined 273 faecal samples from 41 herds. Determination of parasites we performed by morphological characteristics. Molecular detection of Cryptosporidium sp. and Giardia sp. we not performed. Coccidiosis was found at 27 herds. We usally occured mixed infection with 2-3 coccidia species. At sheep most abundant coccidia were E faurei, followed by E.ovinoidalis, E. pallida and E.ahsata. At goats most abundant species were E.arlongy, folwed by E.nina-kohl-yakimovae, E. hirci and E. caprina. Clinical signs of disease were present only at young animals but oocysts were found at both, adult ant young animals. Cryptosporidium spp. was found at 19 herds Clinical signs of cryptosporidiosis were established only at young animals. They had moderate morbidity and mortality rate. Infection with Giardia duodenalis was found only at 2 herds. Giardia-infected animals generally had no clinical symptoms.

AB  - Considering the fact that sheep production has an important role
in agriculture of Serbia, lamb performance is essential. Objective of the study was
to investigate effect of year, lambing season, sex and birth type on growth
performances in lambs of MIS breed. Animal data (birth date, birth type, sex, birth
weight -BW0, body weight after 30 days - BW30 and body weight after 90 days –
BW90) are gained from control of productive parameters maintained from 2011 to
2020. Research was conducted on the sample of 1592 lambs. Average daily gain
from birth to 30 days (ADG1), from 30 to 90 days (ADG2), and from birth until 90
days (ADG3), were calculated and included in analysis. Calendar year was divided
in four seasons, each season consists from 3 months: winter, spring, summer and
autumn. Average body weights (± standard deviation) at birth, after 30 and 90 days
were 4.41 kg (± 0.99), 14.11 kg (± 2.80), 24.05 kg (± 3.86), respectively. Average
daily gains were 319.87 g (± 74.97), 164.98 g (± 35.39) and 216.88 g (± 36.86) for
ADG1, ADG2 and ADG3, respectively. Lambing type and sex of the lambs
affected all of the observed traits very significantly (p < 0.01). Lambing year had
very significant effect (p < 0.01) on BW30, on ADG1 and ADG2, while lambing
season significantly (p < 0.05) affected BW90, ADG2 and ADG3.Based on the
results it can be concluded that birth type and sex had strongest effects in early
productive parameters of lambs.

AB  - This paper describes the present state of goat production in
Central Serbia, discussing the challenges and future prospects for this livestock
system. Number of goats in the country is decreasing and it has been so throughout
the years now. Production systems in goat sector in Serbia are predominately
extensive or semi-intensive, especially in hilly-mountainous areas and goats are
kept in small herds. The majority of goats raised in Central Serbia region are of
French Alpine breed, which takes the most dominant place in breed structure. In
addition to French Alpine breed, there are also Saanen, Balkan and Domestic white
goats. Production of goats in Serbia is directed towards milk-meat, but primarily
milk and there are no typical meat (fattening) breeds of goats in Serbia. In Central
Serbia, herd books are kept for goats raised on this territory. Quality breeding
animals are registered at Central herd book and are under productivity control.
However, this is only a small portion of animals and the productivity of majority of
goats is unknown. Productivity of high yielding breeds such as Alpine and Saanen
goat is inconsistent and not high, especially milk production. Indigenous goat
breeds are considered endangered and their breeding was almost completely
abandoned. Goat sector in Central Serbia is almost completely dependent on
government founding. The only sustainable prospects for preserving goat sector in
Central Serbia for the future are clean organic production, reinforcement of
markets for goat products and smart government founding.

AB  - The study about gastrointestinal helminthes of sheep at central
parts of Šumadija region - Pomoravski and Rasina district was started in March
2016 and finished in October 2018. During our research 937 fecal samples
originated from 62 sheep flocks were collected individual at monthly intervals. A
total of 57 animals we were analyzed by post-mortem examination. Determination
of parasites eggs we performed by keys given by Euzeby (1981). We occured next
parasite species: Haemonchus contortus, Teladorsagia (Ostertagia) circumcincta,
Ostertagia trifurcata, Ostertagia ostertagi, Ostertagia occidentalis, Marshallagia
marshalli, Trichostrongylus axei, Trichostrongylus colubriformis, Trichostrongylus
vitrinus, Nematodirus filicoliis, Nematodirus spathiger, Nematodirus abnormalis,
Cooperia curticei, Cooperia oncophora, Cooperia punctata, Cooperia zurnabada,
Skrjabinema ovis, Bunostomum trigonocephalum, Oesophagostomum venulosum
and Chabertia ovina. Most prevalence species of nematode are Ostertagia,
Trichostrongylus and Nematodirus,species. Although most of the gastro-intestinal
species appear to follow this general pattern of seasonal distribution, some
variations in intensively and duration of these characteristics with different worm
species occurred. Thus with Trichostrongylus and Ostertagia species infection at
mature goats the spring peak was more pronounced that the autumn infection.
Poliparasitismus and infection were established at all examined animals. The
intensity of infection and polyparasitsm was monitored in relation to the age of
sheep. It was found that in younger animals intensity of infection was lower than
that of older animals.

AB  - Pirot breed is a highly endangered autochthonous population of
sheep in Serbia, from which several important national brands originate: Pirot
lamb, Pirot carpet and Pirot hard cheese. In the available literature, there are no
data on hematological and biochemical parameters of the blood of this population.
The aim of this paper, which represents the beginning of the research, is to
determine the above indicators in the blood of Pirot Pramenka, which will
contribute to the preservation of this population. Since the breed affects the value
of blood parameters, the obtained results will be used to define reference intervals
for this population and compare with others. The study included 30 clinically
healthy sheep, 2-3 years old, from the area of Stara Planina. Blood samples were
taken by puncture to c. jugularis from which, after coagulation and centrifugation,
blood serum was extracted. Haematological analyzes were performed in the next
24 hours on a Siemens Advia 120 analyzer. The following parameters were
determined: total number of leukocytes, erythrocytes, platelets, hemoglobin
content, hematocrit value, MCV, MCH, PLT and MPV. Biochemical blood tests
were performed using Olympus AU 400 analyzers.The following parameters were
determined: total protein, albumin, globulin, urea, creatinine, glucose, total
bilirubin, cholesterol. Also, the following minerals were determined - calcium,
phosphate and magnesium, and following enzymes: AST, GGT and CK.
Descriptive statistical analysis was performed using the statistical package
STATISTICA (Version 8). Hematological indicators of Pirot pramenka are in
reference intervals for sheep, which indicates good animal health status.
Biochemical parameters of Pirot pramenka blood were within defined
physiological limits, except for creatinine and phosphorus levels, which were
below the lower limit, which is a consequence of dehydration and reduced
alimentary intake. In accordance with the obtained results, it is necessary to correct
the diet.

abstract = "Pirot breed is a highly endangered autochthonous population of
sheep in Serbia, from which several important national brands originate: Pirot
lamb, Pirot carpet and Pirot hard cheese. In the available literature, there are no
data on hematological and biochemical parameters of the blood of this population.
The aim of this paper, which represents the beginning of the research, is to
determine the above indicators in the blood of Pirot Pramenka, which will
contribute to the preservation of this population. Since the breed affects the value
of blood parameters, the obtained results will be used to define reference intervals
for this population and compare with others. The study included 30 clinically
healthy sheep, 2-3 years old, from the area of Stara Planina. Blood samples were
taken by puncture to c. jugularis from which, after coagulation and centrifugation,
blood serum was extracted. Haematological analyzes were performed in the next
24 hours on a Siemens Advia 120 analyzer. The following parameters were
determined: total number of leukocytes, erythrocytes, platelets, hemoglobin
content, hematocrit value, MCV, MCH, PLT and MPV. Biochemical blood tests
were performed using Olympus AU 400 analyzers.The following parameters were
determined: total protein, albumin, globulin, urea, creatinine, glucose, total
bilirubin, cholesterol. Also, the following minerals were determined - calcium,
phosphate and magnesium, and following enzymes: AST, GGT and CK.
Descriptive statistical analysis was performed using the statistical package
STATISTICA (Version 8). Hematological indicators of Pirot pramenka are in
reference intervals for sheep, which indicates good animal health status.

AB  - Success in lamb production depends on their body weight, and
in recent years there had been a growing interest in understanding the impact of
some factors such as parity on sheep productivity. Knowing the factors that affect
the development and growth of lambs can help make changes in breeding plans.
This paper was to detect important factors affecting lamb's birth weight which
usually are not taken to consideration and have substantial part planning
improvement in sheep production. Miss breed sheep were cross or pair with Ile de
France rams three times, with the following characteristics observed; Body weights
of lambs at birth, type of birth, number of lambs born per sheep per parity in the
periods from 2018 to 2020. The result of each lambing per parity of each ewe was
the basis of the study. The ANOVA, general linear model, univariate analysis of
variance, and descriptive statistics derived to assess the following effects: Effect of
parity on lambs’ birth weight; Effect of parity on birth type, and lambs birth
weight; Interaction effect of different subject effects on birth weight; The
total marginal means of lambing rate per dam in three parities.
The result obtained showed a very significant influence of the indicated factors on
tested traits (P<0.01). Based on the results of our research, we can conclude that
parities have a very significant impact, so they need more attention in the future.

AB  - Due to the political, demographic and economic situation,
agriculture in Serbia changed, including also the structure in sheep breeds.
Traditional sheep breeding centers with large pasture areas and large number of
local breeds and strains are deserted, and, consequently, sheep production focused
on meat production, in intensive systems, but in expensive and inadequate ways.
This led to decreasing number in local breeds (pramenka) with its strains. In this
research, two most numerous pramenka strains were observed, Sjenica and Svrljig
strains, concerning their number, productive and reproductive parameters.
Population of registered and active heads in 2020. was 139,319 for Sjenica and
19585 for Svrljig strain. Weight on birth for Sjenica and Svrljig lambs were 3.20
and 3.15, while weight after 30 days and on weaning was 11.06, 11.42 and 27.02
and 24.97, respectively. Lambing index was 1.27 for Sjenica and 1.29 for Svrljig
strain. Svrljig strain had longer lactation (104 vs. 88 days), with higher milk
production (64.05 kg vs. 55.01 kg), but protein content was higher in Sjenica
sheep’s milk (5.08% vs. 4.19%). Besides their importance on agro-biodiversity and
genetic pool, these strains are best adapted for breeding conditions that are in hilly
and mountainous parts of Serbia. As triple production strains, their milk, meat and
wool could be used in processing to traditional, high-quality products with
additional value, so can provide extra income for the farmers which leads to
survival and sustainable development of rural areas.

AB  - The strategy of conservation of endangered sheep populations
implies morphological and genetic characterization, as basic preconditions for their
conservation. The aim of this study was to determine the morphometric
characteristics, their correlations and the index of physical development of Pirot
pramenka, which has the status of the most endangered population in Serbia. The
measuring was performed on 30 sheep, aged 3 years, reared in the area of Stara
Planina. The descriptive statistical procedure was performed using the statistical
package Statistica (version 8). The average height at the withers was 56.31 cm,
body length 62.93 cm, chest width 18.37 cm, chest depth 25.96 cm, chest
circumference 77.59 cm, shin circumference 6.70 cm. The strongest and
significantly positive correlation (P <0.05) was found between chest depth and
height at withers (0.65), body length (0.58) and body weight (0.56). Pirotska
pramenka has slightly higher indices of format, chest and massiveness, in relation
to breeds Vitoroga Žuja and Travnik Pramenka. These morphometric traits suggest
that, compared to previous research, the body frame of Pirot pramenka sheep did
not change significantly, which means that there were no crosses with other breeds
due to geographical isolation and enthusiasm of breeders to preserve the
indigenous Pirot pramenka which was the starting point for following authentic
brands: Pirot lamb, cheese and carpet. Hence the biological and moral imperative:
to preserve this highly endangered population.

AB  - The effect of different genotypes kept in the same feeding level on microstructure and chemical composition of muscular tissue (musculus longissimus dorsi) of sheep has studied. The study aims to see how the gene combination of different breeds influences the mentioned problem. It was revealed that sheep muscular tissue obtained by crossing the North-Caucasian breeds (NC) and Texel (T) was characterized by a larger quantity of muscular fibres by 4.73 % and 10.14% (P<0.05), and a smaller diameter by 5.65 % and 18.6% (P< 0.05), a higher evaluation of marbling by 5.2 and 8.3 points, less connective tissue content by 0.8 and 1.3 absolute percentage compared to thoroughbred North-Caucasian and from crossing North-Caucasian with Poll Dorset (PD). It showed that meat obtained from crossing animals of the T×NC variant is more delicate, succulent, and has a total higher quality and consumer properties.
The results of different crossing indicate the reasonability to use morphological characteristics of muscular tissue on the histological level when the quality of sheep slaughtering performance had evaluated.

It was revealed that sheep muscular tissue obtained by crossing the North-Caucasian breeds (NC) and Texel (T) was characterized by a larger quantity of muscular fibres by 4.73 % and 10.14% (P<0.05), and a smaller diameter by 5.65 % and 18.6% (P< 0.05), a higher evaluation of marbling by 5.2 and 8.3 points, less connective tissue content by 0.8 and 1.3 absolute percentage compared to thoroughbred North-Caucasian and from crossing North-Caucasian with Poll Dorset (PD). It showed that meat obtained from crossing animals of the T×NC variant is more delicate, succulent, and has a total higher quality and consumer properties.
The results of different crossing indicate the reasonability to use morphological characteristics of muscular tissue on the histological level when the quality of sheep slaughtering performance had evaluated.",

AB  - DNA analysis can have great practical application in the
management and successful operation of the farm. The application of DNA
technology is becoming a tremendous challenge for farm breeding of domestic
animals. In recent years, traditional selection methods have been supplement by the
results of molecular analysis of the genome. Determining the genetic distance of
sheep and goat breeds had practical and multiple significance. Microsatellites are
used widely in the selection, and genomic selection is becoming an increasing
challenge for breeders. The development of SNP chips brings an immense
advanced for rapid and comprehensive analysis of the genome, which is of great
importance for the successful selection and Genomic selection in sheep
concentrated on all aspects of genetic and production directions. However, it
should be noted that genomic selections in sheep breeding, and especially in goat
breeding, take place at a slower pace compared to cattle breeding.
