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  - 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  - 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.

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

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,

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
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).

AB  - The current study aimed to examine the percentage changes of
viability sperm and the activity of the enzymes LDH, ALP, GOT / AST, GPT /
ALT in the sperm plasma of Lacaune rams, before and after cryopreservation. For
this purpose, five rams were examined, and two ejaculates were obtained from each
ram. Ejaculates are collected by the method of artificial vagina, during the
insemination campaign. All ejaculates were diluted with a 6AG extender and
frozen by the Cassou’s sequin method. Sperm viability was determined by eosin
and nigrosine smears, and enzyme activity was examined spectrophotometrically.
As a result, the percentage of vital sperm after cryopreservation decreased by 15%
(P ≤ 0.001). The freezing and thawing process also reduced the activity of the
enzymes LDH, ALP, GOT / AST and GPT / ALP. In conclusion, the observed
enzymes, in relation to sperm vitality, could be used as indicators to optimize the
protocols for cryopreservation of ram’s sperm.

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  - 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.

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  - 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.

AB  - In addition to nutritional value, a very important criterion for the selection of meat, for the modern consumer is the health aspect, i.e. the content of fat and the profile of fatty acids in meat. The content of fat and fatty acids, among other things, is conditioned by the feeding system and the rearing method. Lambs fed on pasture have a lower share of fat in the carcass than animals fed with a concentrated mixture, in a closed system. The recommended value for the ratio of polyunsaturated to saturated fatty acids is up to 0.45, and below 4.0 for the n-6 and n-3 fatty acids ratio. Taking into account that the influence of lamb nutrition on these relationships is significant, modelling of fatty acid composition should be directed to the lamb nutrition system which leads to a decrease in the content of saturated and an increase in the concentration of polyunsaturated (PUFA) fatty acids in meat. A feeding strategy involving a grazing feeding system of lambs results in a higher content of n-3 PUFA, CLA and a more favourable n-6/n-3 ratio of fatty acids, while the lamb meat originating from animals fed concentrated diets has a higher proportion of n-6 PUFA and a higher n-6 ratio/n-3 fatty acids, which exceeds the recommended value of 4.0. Conjugated linoleic acid (CLA) is of great importance since it has an anticancer, antidiabetic effect as well as an effect on the immune system, suggesting a direction for future research on lamb meat.

AB  - Quantitative genetic analysis of variability and relationship of
lambs body weight traits in indigenous pirot sheep population are done. The the
examined lambs had high variability which very suitable for selection on a larger
weight. There is a high and very significant correlation between the body weight of
lambs with 30 and 60 days (.969 **) and the weight with 30 and 90 days ( .914 **).
There is also a highly significant correlation between the weights of lambs with 60
and 90 days of age (.904 **). From our research, we can see that the first month of
the lamb's life is very important for the further development of the body. There is
different level of correlation between weight of lambs. This gives us an idea to say
that many paragenetic factors are crucial for the growth of lambs from birth to
weaning. The coefficient of multiple determination (R2) is 0.845 which means that
8.45% of the lamb's body weight variance at 90 days is determined by the variance
of the set of predictor variables (PI-60, 30, 1). Each increase in lamb body weight
during the observed periods of age is associated with an increase in the score of
depending variable PI90. In particular, any increase in lamb body weight at birth
by 1 kg is associated with an increase in lamb body weight from 90 days by 0.238

AB  - The body weight of calves in the earliest period of their life (age
from 0 to 7 days) is under the greatest influence of the farm and the season of birth.
The farm manifests its influence most often through the conditions of nutrition and
housing and the organization of the technological production process, while the
influence of the birth season is manifested through microclimatic and nutritional
conditions, as well. The most common deficiencies related to the nutrition of
newborn calves are related to: inadequate colostrum supply in terms of quality,
quantity and time of colostrum intake, which is closely related to the organization
of the technological production process on the farm. Dietary deficiencies affect the
body weight of calves at birth and at 8 days of age. In a study conducted over a
year (4 seasons), the colostrum diet of newborn calves of the HF breed on two
farms (A and B) with a tied housing system was analyzed. Calves were fed
colostrum on both farms at intervals, usually up to 2 hours, less often up to 4 hours
after birth. The colostrum consumed came from the mother, most often, and less
often from the other cow, while on one of the farms it was also used frozen.
However, the amount of colostrum consumed was deficient, it was 1-2 l on farm A,
and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in
the diet of calves was indicated by the average body weight, measured at birth and
at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and
39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories,
respectively. The average body weight of calves was statistically significantly (p
<0.01) influenced by the farm and the season of birth, as well as their mutual
interaction, but the effect of the farm was more pronounced.

and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in
the diet of calves was indicated by the average body weight, measured at birth and
at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and
39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories,
respectively. The average body weight of calves was statistically significantly (p
<0.01) influenced by the farm and the season of birth, as well as their mutual
interaction, but the effect of the farm was more pronounced.",

AB  - Crossbreeding serves as a predictable and cost-effective method
to genetically increase lamb body weight by mating two or more breeds of sheep.
The crossing over breed comes to a far greater number of combinations of genes
and thus is more likely to express favorable allele carriers of economically
important traits. The phenomenon of heterosis has used since the beginning of the
last century. However, its genetic basis has remained unclear. From the very
beginning of the knowledge of heterosis to the present day, there are several
theories, but neither theory able to answer all questions that arise regarding the
apparent strength of the F1 generation offspring. Not assert anything about the
genetic or molecular phenomenon that causes heterosis. It has been increasingly
experimentally confirmed that heterosis is the result of highly complex interactions
within the genome as well as between the genome and the environment. In Serbia,
some activity of domestic researchers regarding crossbreeding of sheep after the
Second World War has been recorded up to date. It found out that crosses have a
higher body weight than the maternal base in the F1 generation. In other words,
they had better fattening capacity than purebreds. However, the results are not
always in line with expectations due to the influence of various known and
unknown factors.This review paper aims to draw attention to the phenomenon of
heterosis through experience in its application in Serbia, in the hope that this
biological phenomenon would clarify in the near future by applying modern
scientific understandings and technologies.

AB  - The area of central Serbia is very suitable for sheep production, because of it’s hilly and mountainous configuration. Such area is rich in pastures for ruminants. In the territory of central Serbia, representative of autochthonous (indigenous) sheep breeds is pramenka (zackel) with its differentiated strains: Sjenica strain, Svrljig strain, Krivovir strain, Karakachan strain, Pirot strain, Lipa strain and Bardoka (White Metohian strain). Aim of this study was to investigate Krivovir strain: number of controlled heads and their part in total sheep population, their productivity parameters and milk parameters. In this study, total of 789 adult animals were observed. Average observed body weight (BW) of lambs were: BW on birth 3.22 kg, BW after 30 days 10.55 kg and BW on weaning 24.99 kg, while BW of adult sheep was 50.52 kg. Fertility index was 1.17 and average wool production was 2.88 kg. Average lactation after weaning lasted for 100 days, with milk production 65.16 kg, 3.91% protein and 6.72% milk fat. Krivovir strain is participating with 0.4% of total number of controlled sheep in central Serbia. Although in small number, this strain is irreplaceable in sustainable systems because they are evolutionary adapted to the conditions in which they are reared and because of their contribution to gene pool and agro-biodiversity.

AB  - The high price of protein nutrients as well as import orientation
have triggered the demand for alternative protein sources in the feeding of lambs.
In addition, it is necessary to take into account the degree of degradability of
proteins. In order to ensure optimal amino acid pool for high genetic capacity of
lamb growth, it is important to provide a protein fraction that avoids degradation in
the rumen. An excellent source of protein that slowly degrades in the rumen is fish
meal. However, given the recommendation of its non-use, the effects of the use of
Eko fish meal, as a fishmeal substitute in diet of lambs of average body weight of
about 14 kg and age of 30 days, were examined. The source of protein did not
significantly affect the growth rate and the efficiency of food utilization in the
lambs of MIS population in fattening (P>0.05), suggesting that fish meal can be
successfully replaced by Eco Fish Meal. As an alternative to soybeans, in diet for
lambs in fattening, the following were used: sunflower meal with the addition of
fibrolithic enzyme, lupine, fodder peas, fodder beans were used, while in the more
exotic areas the following were used: castor cake, pomegranate peel, product
obtained after rice fermentation without any harmful effect on the biological
efficiency of growth and food conversion.

AB  - Central Serbia has a long tradition of cattle farming and, as a
hilly-mountainous area it favors rearing of dual purpose Simmental breed, and to a
lesser extent, Holstein-Friesian dairy breed. The first Herd Book of Serbia was
founded in 1935. The high quality breeding animals registered are under the
control of production performance properties. According to expert report of the
Institute for Animal Husbandry and the results of the implementation of the
breeding program in 2018 in the territory of Central Serbia, there were a total of
153.979 quality breeding animals of Simmental and 16509 quality breeding
animals of Holstein-Friesian breed in the main herd. Both breeds are of national
interest and are included in the breeding-selection program for dairy cattle that are
implemented through the cooperation of breeders and breeding organizations in the
field. In Central Serbia, there are 157 registered breeding organizations involved in
breeding and livestock recording activities. In this paper, data of the Head breeding
organization in cattle farming, the Institute for Animal Husbandry, as well as
reports issued by the same entity each year were used. A tabular analysis and a
five-year trend are presented according to: the number of recorded animals,
primiparous females in linear evaluation, the realized yield of milk, milk fat and
protein, as well as the trend of the number of bull dams in the population. Based on
the analysis of the results of work on cattle breeding and selection, it can be
concluded that some progress has been made in milk production of both breeds. It
is important to emphasize that there is a significant effect of mentioned factors on
the productivity of entire cattle population in Central Serbia. Systematic work on
the breeding and selection of cattle is an important work that should be carried out
in high quality, continuously and appropriately in order to achieve maximum
effects in cattle production.
