AB  - The aim of the research was to determine the fertility of purebred sows (Large White -LW, Landrace -L, Swedish Landrace -SL, Danish Landrace - DL, Duroc -D, Pietrain -P, Hampshire -H, Norwegian Landrace -NL, German Landrace -Ne.L.) and seven F1 hybrid genotypes (Landrace and Large White). The influence of genotype and parity of sows on litter size traits (Number of live born piglets -NLBP, number of stillborn piglets -NSP, total piglets born -TPB, number of reared piglets and litter weight) and lactation duration was examined. Research showed that the highest number of live born piglets was in F1 crossbreeds (13.36 NLBP), while among purebreds the highest NLBP was in the Landrace breed (12.44 NLBP) and Large White (12.17 NLBP). Looking at parities for all tested genotypes, NLBP in the first litter was over 11.53 piglets. For breed L and LW, the highest NLBP was in the fourth litter 12.88 and 12.55 piglets. F1 crosses LxLW (♀Lx♂LW) also had the highest NLBP in the fourth litter 12.85 piglets. For the genotype F1 crosses LWx L (♀LWx♂L), the highest average number of live-born piglets was 12.32 piglets in the second and third litters. Variation in litter size at birth and weaning by genotype and parity was statistically significant (P<0.01), except for the number of stillborn piglets of L sows by parity, where a significant difference was found (P<0.05).

AB  - The morphometric characteristics of the gonads of male autochthonous breeds of pigs in the
Republic of Serbia were examined. The following breeds are included: lasasta mangulica (Swallow-Bellied Mangalitsa), Moravka and Resavka. There were 3 age categories divided by body mass within the group of Swallow-Bellied Mangalitsa. The first group are animals of average body mass 20 kg (n=11). The second group is the average body mass of 45 kg (n=9), and the third group are pigs of body mass of 100 kg (n=13). Number of Moravka male were 8, until number of Resavka was 7 adult animals. The morphometric properties that were investigated were: ZAPSAEP- Volume of testes with the epididymes; ZAPBEZEP - Volume of testes without the epididymes; ZAPEP-volume of epididymes; MASSAEP- Weight of testes with the epididymes; MASBEZEP- Weight of testes without the epididymes; MASEP- Weight of epididymes; DUŽSAEP- Length of testes with the epididymes; DUŽBEZEP- Length of testes without the epididymes;
DUBBEZEP- Thickness of testes; ŠIEBEZEP- Width of testes; OBBEZEP- Circumference of testes. The characteristics of length and thickness in the youngest group of Mangalitsa had a coefficient of variation for the left and right testis of less than 30%, as well as for the group up to 45 kg of body weight. Length traits in the oldest group of Mangalitsa had smaller coefficients of variation for the left compared to the right testis (12.70; 10.86 toward 13.76; 12.22%). The absolute size of the left testicle was larger in non-castrated male of the Mangalitsa breed, as indicated by all the morphometric measurements taken on the testicles. The characteristics of testicular volume varied within the Moravka breed, in contrast to the Mangalitsa, in Moravka males, a larger volume of testicles with the epididymis on the right side compared to the left was determined, which is a consequence of the larger volume of the right epididymis. In contrast to the Moravka, lower values of the characteristics of the volume of the right testicle compared to the left were found in male
Resavka. Traits of volume, length, depth, and weight in Mangalitsa males had coefficients of variation of less than 30% for left and right testis. In sexually mature animals, the correlation between morphometric measures is strong and positive, which allows us to take one measure (which is the simplest to take), to gain an objective insight into the size of the testes. The association of age and body mass at slaughter with a number of morphometric traits of the Mangalitsa breed was moderate to strong with a positive sign. The connection between the morphometric characteristics of the testicles and the production characteristics of male pigs of the Moravka breed, unlike the Mangalitsa, looking at the established correlation coefficients in the Moravka, it is not possible to draw clear conclusions when it comes to the connection of these groups of characteristics. Within the Resavka breed, of the production traits, only the average lifetime daily gain has a strong correlation with the trait of testis length without epididymis, but with a negative sign.

AB  - The aim of this research was to determine the phenotypic and genotypic variability of the
observed traits in the performance test of gilts: age at the end of the test - final age (FA), back fat thickness 1 and 2 (BFT1 and BFT2) and back muscle depth (MLD). Production performance of gilts was examined in two pig pens in three consecutive years. The research included 3610 gilts, 3 genotypes, originating from 84 sires. At the end of the test, the body weight and back fat thickness (BFT1 and BFT2) and MLD depth were measured using a MLD-ultrasound device. There were 1228 gilts in the first pen, and 2382 tested gilts in the second pen. In the first year, 885 gilts were tested, in the second 1145, and in the third 1580 gilts. Based on the obtained results, it was determined that the genotype of gilts had a statistically significant effect (P<0.001) on BFT1, BFT2 and MLD, while it had no effect on the FA trait (P>0.05). Taking into consideration the farm as a source of variation of gilts’ traits, it was concluded that it had a very high statistically significant influence on the investigated traits (P<0.001). The year of testing of gilts as a source of variation of their traits showed a high statistical effect (P<0.001) on all tested traits. The observed properties of back fat thickness 1, 2 and MLD depth were highly statistically dependent (P<0.001) on the weight at the end of the test. Medium heritabilities were determined for production traits in the performance test of gilts, for age at the end of the test 26%, back fat thickness 1 - 37%, back fat thickness 2 - 35%, and for depth of MLD 23%.

AB  - The study encompassed 135 piglets of the Large White breed and aimed 
to evaluate the impact of a live yeast feed supplement on key production 
parameters—namely, feed intake, average daily gain, and feed conversion—among 
growing piglets. The trial spanned a total of 39 days, divided into two distinct 
periods. The initial phase, lasting 28 days (from day 22 to day 49), was followed by 
a shorter 11-day second phase (day 50 to day 60). Throughout the observation 
periods, two distinct feed mixtures were employed, as outlined in Table 1. The 
control groups were provided standard farm mixtures, while the trial groups 
received the same mixtures supplemented with varying concentrations (3% and 
4%) of the commercial live yeast dietary supplement, Biokvas-45. During the 
initial period, statistical analysis indicated no significant differences (p>0.05) 
across all three observed parameters between the groups. However, notable 
disparities emerged during the second period. Specifically, feed intake (FI), 
average daily gain (ADG), and feed conversion ratio (FCR) displayed variation 
between the T1 and T2 groups. The T2 group exhibited particularly favorable 
performance, achieving an impressive average daily gain of 563.24 g/d and a 
commendable feed conversion ratio of 1.92 g/g. Considering the entirety of the 
trial, the T2 group consistently outperformed the other trial groups in terms of 
average daily gain, achieving a rate of 348.26 g/d. The results collectively indicate 
that the incorporation of the dietary supplement Biokvas-45 holds promise as a 
beneficial addition to the nutrition of growing piglets. However, further research is 
warranted to comprehensively assess the supplement's effects on pigs during the 
fattening phase. These findings contribute to a growing body of knowledge that 
could potentially lead to more effective nutritional strategies for pig farming.

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  - The study of the production traits of 22 genotypes of fattening pigs was carried out on two pig farms (Farm A and Farm B) in Central Serbia, under the influence of the following factors: farm, genotype and sex of fattening pigs, and pre-slaughter weight. The characteristics of fattening animals included in the research are: warm carcass side growth (WCSG); bacon thickness - rump (FTR); bacon thickness - back (FTB); bacon thickness - rump + back (FTRB); meat yield – carcass sides (JUSKG) and meat yield in percentage (JUSPRO), as well as weight and ratio of French dressing in warm carcass sides (FDKG and FDPRO). Animals of both sexes were used in the trial (female non-castrated rats and surgically castrated males). Total of 1166 fattening animals were included in the trials. Statistical data processing was performed using the Harvey software package. All included factors in the used models show a highly statistically significant effect on the variation of fattening traits (P<0.01; P<0.001). Animals of genotype DxSL (44.97%) had the highest share of meat in carcass sides, and animals of genotype SL (44.63%) for the trait JUSPRO, while for the trait FDPRO the highest value was recorded for the genotype DXSL (54.45%). In our study, animals of the genotypes (HxD)x(WxD) and Dx(WxD) had the highest values for bacon thickness - 39.95 and 38.32 mm, respectively, which implies lower share of meat in the carcasses. By calculating the genetic and phenotypic correlations, we came to the conclusion that the phenotypic correlation of the carcass side traits was of different strength (from very weak to complete) and different sign, while the genetic correlations were stronger than the phenotypic, so the genetic correlations between the bacon thicknesses FTB and FTR were complete, and between meat yield and traits FTB and FTR complete and negative.

AB  - The importance of pig production in total livestock production in Republic of Serbia and the world is
presented in this paper, especially given the high share of porcine in total meat production. The economic
efficiency of pig production, i.e. fattening of pigs, is observed through three most important indicators of
production: annual production of fattening pigs per sow, feed consumption per kilogram of growth and
meatiness of fattening pigs. The mentioned economic indicators primarily depend on the genetic potential
of the parents, environmental factors and management. The largest producer of pigs and pork is China. In
2020, 43.27% of total number of pigs in the world were farmed in China. In the same year, 8.11% and
4.32% of the total number of pigs were reared in the USA and in Brazil, respectively. The remaining
countries have a significantly smaller number of animals. The biggest decline in numbers from 1999 to
2020 was recorded in Bulgaria (65%), the Czech Republic (61.35%), Hungary (48%), Serbia (32%) and
Belarus (22%). Serbia participated with 0.31% in the total number of pigs in the world in 2020. The
largest producer of pork in 2020 was China with 38.33% of the total meat production. The USA (11.69%),
Germany (4.66%), Spain (4.56%) and Brazil (4.08%) followed in terms of their share in the world meat
production. In relation to the world production of pork, Serbia's share in 2020 was only 0.28%. In regard
to the total production of all types of meat in our country, the share of porcine meat is 58.4%. In Serbia,
evaluation of meatiness is carried out using ultrasound devices in vivo and in vitro, using automatic
devices for evaluating meatiness or by manual measurement using two points at the slaughter line.

AB  - This research was aimed at evaluating carcass differences between surgical and immunocastrated fatteners of Mangalitsa breed. The study comprised 23 male pigs kept under the identical managament conditions and divided in the two groups: surgically castrated (SC, n=11) and immunocastrated (IC, n=12). The animals were kept in a semi-outdoor system facility with open (100 m2) and covered (40 m2) part. Pigs under investigation were fed complete feed mixtures (15% and 13% of crude protein and 13.5 MJ ME/kg). Carcass traits measured on the slaughter line included: warm and cold carcass weight (kg), carcass length (cm), share of the main parts in half-carcasses (ham, loins, shoulder, rib-abdominal part; %), fat and longissimus dorsi muscle thickness (mm). Thickness of subcutaneous fat measured at three points; where m. gluteus medius gets deepest into the fat tissue; at the level of the first rib – between the last neck and the first thoracic vertebrae; at the level of the last rib – between the last thoracic and the first lumbar vertebrae. Muscle thickness measured from the end of the spinal column to the cranial part of the m. gluteus medius. At slaughter, SC and IC group of pigs had live weight of 116 and 121 kg, respectively (p>0.05). Warm and cold carcass weight in SC, compared to IC group, was higher by 2.2, i.e. 2.4 kg, respectively (p<0.001). The length of one carcass half measured from the anterior edge of pudendal bone up to an atlas cranial edge was similar (100 and 99 cm in IC, i.e. in SC group, respectively; p>0.05). The fatteneres in the IC group had a higher share of carcass ham (11.4 vs. 9.9%, p<0.001). Loins share in halves was greater in SC group (+1.1%, p<0.05). Thickness of subcutaneous fat at the three points was higher (p<0.01) in SC group by 12.2, 11.7 and 11.6 mm. Longissimus dorsi muscle thickness was 61.9 and 57.5 mm in the SC and IC group (p>0.05), respectively. The immunocastrated group had better carcass traits, considering that they had i higher share of ham in carcass and lower fat thickness.

AB  - The study aimed to determine the effect of different fixed factors (breed, region, calving year,
calving season, parity and lactation stage) on daily milk production (yield and content) of four
dairy cattle breeds under the heat stress conditions (THI≥72). The research was conducted
on a set of test-day records of four dairy cattle breeds (Simmental, Holstein-Friesian, Red
Holstein and Brown Swiss) reared in the Republic of Serbia (Region of Mačva, Podunavlje and
Šumadija). The statistical analysis included test-day records collected in the period from the
beginning of the year 2012 to the end of the year 2019. Based on the performed analysis, it
could be demonstrated that all the effects included in the statistical model (breed, region,
calving year, calving season, parity and lactation stage) statistically highly significant (p<0.001)
affected daily milk production (yield and content) of cows reared in the terms of the heat stress
conditions. The highest daily milk production was determined in the region of Podunavlje, and
by the Holstein-Friesian breed. Furthermore, dairy cows calved during the spring season, in the
third lactation and from the 61st to the 120th day of lactation, had the highest milk production
during the summer period in an environment characterised by heat stress. Also, daily milk yield
of cows in a heat stress environment decreased in the period from June to September. The
results obtained indicate different animals’ responses to heat stress concerning the animal’s
breed, rearing region, calving year, calving season, parity and lactation stage.

AB  - Simple Summary: In the Republic of Serbia, pig selection in recent decades has been based on
genetic improvement of growth and carcass quality traits. Genetic improvement of reproductive traits of pigs was based on the so-called phenotypic selection. The introduction of modern information systems and the availability larger dataset have opened the possibility to perform genetic estimation of reproductive traits within the main breeding programme of the Republic of Serbia. Using the methods of gene flow and connectedness evaluation, our study investigated the possibility of improving the reliability of estimating the breeding value of reproductive traits in highly productive sows. We believe that these methods could lead to a systematic improvement of the genetic value of reproductive traits in sows. Thus far, none of the methods for estimating the degree of connectedness between herds in pigs has been used in the preparation of the National Breeding Programme of the Republic of Serbia.
Abstract: This study investigated the influence of the degree of connectedness on the reliability of
the estimated breeding values (EBVs). The focal trait in the study was the number of piglets born
alive (NBA) from sows of the highly prolific Large White and Landrace sows. An analysis included
total of 58,043 farrowing’s during the 2008–2020 period. BLUP procedure was used to estimate the breeding values for NBA for the three herds separately and after merging all three herds into one herd. The model for EBV estimation included the following fixed factors: parity, genotype, seasons, litter sire, herds, sow age at farrowing, weaning-conception interval, length of previous lactation, and the following random effects: common litter environment, permanent litter environment, and direct additive genetic effect of animal. Heritability values for NBA ranged from 0.048 to 0.097, depending on the data included in the analysis. The connectedness between herds was analysed using the connectedness rating (CR) and the gene flow (GF) methods. CR among the observed herds ranged from 0.245 to 0.994%, depending on the data included. The exchange of genetic material between all three herds was determined using GF method. The high degree of connectedness determined by the CR and GF method had a strong effect on EBV reliability. The average EBV reliability ranged from 0.520 to 0.867, depending on the data included. The increase in average reliability was observed in both cases when the data were added, both in the analysis of average reliability for purebred animals and when crossbreeds were added, where an increase in this value was also observed. The increase in average EBV reliability is a consequence of the greater amount of information included in the joint evaluation. In conclusion, we believe that our research will improve EBV reliability and help in further selection work in the Republic of Serbia.

AB  - In recent years, the popularity of local pig breeds has increased in the
Republic of Serbia. Local pig breeds such as Mangalitza, Moravka and
Resavka, have again found their place in rural households and in the
overall biodiversity of Serbia. Their increasing number led to a diversity
of production systems and feeding types. They ranged from fully
intensive systems with commercial mixtures to completely extensive
without supplementing any additional feed except what the animals find
on the ground. Aim of this study was to determine the differentiation of
these systems by region and to examine the differences between them.
We classified all these production systems into six categories: intensive
systems using commercial mixtures, intensive systems using cereals,
vegetables and fruits as the main feed, semi-intensive systems using
commercial mixtures, semi-intensive systems using cereals, vegetables
and fruits as the main feed, extensive systems using cereals, vegetables
and fruits as supplemental feed and completely extensive systems. We
studied the main advantages and disadvantages of these systems,
including economic factors. The results showed extreme differences,
especially in animal size, investment, and economic aspects. Contrary to
wide opinion the lowest investments were on farms with fully intensive
systems because they used old concrete buildings that were used for
commercial breeds in the past. On the other hand, breeders with full
extensive systems have made the most investments, considering the cost
of the land. The size of the animals and the type of feed used were in
positive correlation. Animals fed commercial mixtures were almost double in size and weight than those raised in fully extensive way. The
cost of feed dictates which feeds are used in the animal’s diet, especially
considering grains, vegetables, and fruits. Although the investment in
fully intensive systems is lower, the health aspect and welfare of the
animals in these systems should be studied. Besides the health aspect, it
is questionable how these breeding systems affect the quality of the final
products of these local breeds. Furthermore, it will be interesting to
investigate how each of these breeds performs in all these production
systems. Also, further studies will investigate how these types of
production systems affect the value of the final pig products on the
market.

AB  - The trial was conducted on 108 piglets of crossbreeds Landrace
x Large White. Aim of this study was to determine influence of this aroma on
production parameters of growing pigs. Whole trial was in total 57 days, and it was
split in three trial periods. Piglets were weaned on day 27, when the trial started.
First trial period was 18 days (27-44 day), second was 28 days (45-72 day) and
third was 11 days (73-83 day). The control groups received standard farm mixtures,
and the trial groups had added aroma Vanilla Sweet in different concentrations
(0.02; 0.04%, respectively). During the first period, there was statistical difference
(p<0.05) in all three prameters between the groups. Feed intake (FI), average daily
gain (ADG) and feed conversion (FCR) differed between C and T1 group. T1 had
best ADG of 261.53 g/d and FCR of 1.89 g/g. In the second period statistical
significance was noted in FI and ADG, between T1 and other two groups. T1 had
lower FI and ADG, but better FCR compared to control group. In the final period
second experimental group had the best results in both FI (1309.29 g/d) and ADG
(696.43 g/d). And eventualy for whole trial T2 had better results in all three
production parametars compared to other two trial groups. In general, obtained
results showed that use of Vanilla sweet aroma can be recommended in the
nutrition of weaned pigs. Further investigation should be conducted to determine
the effect of this flavour on fatteners.

AB  - The aim of this study was to determine the influence of sow genotype, year of farrowing and parity on the number of live-born piglets. Fertility traits of sows were tested during fourteen years (from 2007 to 2020) in one pig herd/population. The study included 10159 sows, 4 genotypes: Landrace, large White, Landrace x large White and large White Yorkshire x Landrace. The sow fertility data set contained data on 36189 parities. Based on the obtained results, it was determined that the genotype of sows, year of farrowing and parity had a statistically highly significant (P <0.01) influence on the number of live - born piglets.

abstract = "The aim of this study was to determine the influence of sow genotype, year of farrowing and parity on the number of live-born piglets. Fertility traits of sows were tested during fourteen years (from 2007 to 2020) in one pig herd/population. The study included 10159 sows, 4 genotypes: Landrace, large White, Landrace x large White and large White Yorkshire x Landrace. The sow fertility data set contained data on 36189 parities. Based on the obtained results, it was determined that the genotype of sows, year of farrowing and parity had a statistically highly significant (P <0.01) influence on the number of live - born piglets.",

AB  - A primary objective of this study was to determine the effect of breed, frequency of utilisation, boar age and season on following sperm characteristics: volume of ejaculate (ml), sperm concentration (x1000000 spermatozoa/ml), total count and count of functional spermatozoa in ejaculate (x1000000000 spermatozoa), motility of spermatozoa in native ejaculate and after dilution (%), number of produced doses, percent of dead and viable spermatozoa. Research included 4 boars of Landrace breed (n=40 ejaculates) and 13 boars of Large White pig (n=89 ejaculates). Ejaculates were analyzed during two seasons (summer and autumn), a dividing line being a calender start of autumn. Interval between two mounts was observed on two levels: ≤7 and ≥ 8 days. The assessment of the effect was done by means of a General Linear Model procedure. Breed and frequency of utilisation did not affect an average expression and variability of sperm
characteristics. By increasing boar age by one day the volume of ejaculate increases by 0.142 ml. In ejaculates taken during autumn season a higher concentration of sperm per ml of ejaculate by 53.38x1000000 spermatozoa (p=0.033) was determined. Higher motility (p<0.001) of native i.e. diluted semen of 5.7, i.e. 8.2% was determined in ejaculates taken during summer season. A higher percent (+13.47%; p<0.001) of dead spermatozoa was determined in ejaculates in autumn season.

AB  - Indigenous breeds of pigs, in addition to representing genetic heritage, have great scientific, cultural and economic significance for every country. The Serbian indigenous breeds of pigs Mangalitsa, Moravka and Resavka are endangered breeds with little research interest, which resulted in insufficient data on their production results. The aim of this study was to determine the
differences in the life daily gain (LDG) of male heads of Swallow Belly Mangalitsa breed of different body weights (20 kg - I group, 45 kg - II group and 100 kg - III group), as well as between males of Swallow Belly Mangalitsa, Moravka and Resavka in seven consecutive measurements, once a month, during the experiment. Within the Swallow Belly Mangalitsa breed, the third group (280 g/day) had a statistically significantly higher LDG compared to the first (110 g/day) and the second (200 g/day). In all measurements, Moravka had the highest LDG, and Mangalitsa the lowest, but the differences were not significant. It was to be expected that the Mangalitsa would have the lowest LDG because it is a fatty breed, unlike Moravka and Resavka, which are breeds of combined production abilities (meat and fat). By researching the production performance of indigenous pig breeds, it is possible to predict and improve production possibilities by selection measures while preserving the desired genetic structure.

AB  - The effects of the use of fish meal in the nutrition of weaning piglets were observed. The trial included 80 weaned piglets of the same genotype (Large White x Danish Landrace) distributed in two feeding treatments. In the first period of the experiment, animals were fed during 10 feeding days, with a pre-starter mixture containing 21.1/20.8% of the crude protein. The second period lasted for 25 days and piglets were fed with mixture containing also 21.0/21.1% of the crude protein. And in the final period of the experiment, which lasted 22 feeding days, the meals were formulated to contain 19.5/19.9% of the crude protein. The control group was fed with standard farm mixtures, while the trial group were fed with mixtures containing 4/3/2% of fish meal. The obtained results showed that the use of fish meal resulted in better average daily gain and feed conversion in starter period (27-51 day).

AB  - The production traits of gilts were examined in two pig herds for three consecutive years. The study included 3,610 gilts of 3 genotypes, originating from 84 boar sires. The test included only those boar sires who had 10 or more daughters. At the end of the test, the weight and thickness of the fat (FT1 and FT2) and depth were measured by anBMD ultrasound apparatus. The aim of this study was to determine the phenotypic and genotypic variability of the observed traits in the performance test of gilts: age at the end of the test (FA – final age), lifetime daily gain (LDG), fat thickness 1 and 2 (FT1 and FT2) and back muscle depth (BMD). In the first herd there were 1228 gilts and in the second 2382 gilts tested. Within the Landrace (L) breed there were 1962 gilts, Large white (LW) 1324 and Duroc (D) 319 gilts. In the first year, 885 gilts were tested, in the second 1145 and in the third 1580 gilts. Based on the results obtained, the genotype of gilts was found to have a statistically significant effect (P<0.001) on FT1, FT2 and BMD, while LDG was unaffected (P>0.05). Considering the farm as a source of variation in gilt traits, it was concluded that the farm had a highly significant statistical effect on the traits tested (P<0.001). The year of testing of gilts as a source of variation in their traits showed a high statistical influence (P <0.001) on all traits examined. Observed traits - fat thickness 1, 2 and BMD were highly statistically dependent (P <0.001) on the weight at the end of the test.

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

AB  - The main objective of the study was to determine the influence
of breed on the traits of boar ejaculate: ejaculate volume (VOL, ml), sperm
concentration (CON, x106 sperm/ml), total sperm count in ejaculate (TNS, x109
spermatozoa), sperm motility in native ejaculate (MON, %), sperm motility after
dilution (MOD, %) and number of doses produced (NPD). The aim was also to
evaluate the correlation of the boar performance test traits: average life daily gain
(g), backfat thickness measured in two locations (mm), depth of longissimus dorsi
muscle (mm) and carcass meat content (%) with ejaculate traits. Total of 931
ejaculates of 36 boars during reproductive exploitation were analysed (16 Landrace
boars and 20 Large White boars). The effect was assessed using the procedure of
the general linear model of the statistical package SAS 9.1.3 (SAS Inst. Inc., 2002-
2003). The model for analysis included the influence of breed, season and the
linear regression influence of body weight at the end of the performance test. The
correlation of the traits was determined by applying the Pearson’s correlation
coefficient. Most of the examined ejaculate traits (VOL, CON, MOD and NPD)
varied under the influence of boar breed (p<0.01; p<0.001). Weight at the end of
the test (p<0.05; p<0.01; p<0.001) affected all examined traits, except CON and
TNS. A weak association was found between production performance and
ejaculate traits.

AB  - The aim of this study was to determine the influence of the
applied method of the quality carcass in 201 descendants, both sexes (n=108 male
castrated animals and n=93 females), of studied boar-sires. For the determination
of the meat yield (JUS1) and the share of meat (JUS 2) in carcass sides, on the
basis of the performed measurements, tables for meat pigs, which are an integral
part of the Rulebook on the quality of slaughtered pigs and categorization of pork
meat (OG SFRY, 1985), were used. Share of meat (EC 94 and EC 06) was
determined on cooled left carcass sides by method of partial dissection (according
to methodology recommended by EU- Walstra and Merkus, 1996). Research was
carried out on pig farm and in experimental slaughterhouse of the Institute for
Animal Husbandry, Belgrade-Zemun. Housing, care and nutrition of animals were
in accordance to breeding technology in investigated herd. The average share of
meat determined by the application of the Rulebook (JUS2) was 43.58% with a
lower absolute variation compared to the EU regulation from 1994 (EC 94;
53.56%) and from 2006 (EC 06; 56.55%). The estimated lean meat content by the
application of the Rulebook (JUS 2) was by 9.98% lower compared to the EC 94
regulation and by 12.97% lower compared to EC 06. If we are talking about the
selection of offspring for breeding, if we consider only the estimated leanness, we
see that within the Landrace (L) breed we have high and very significant (P<0.001)
differences between the sires for the assessed meat content according to EC 94 and
EC 06. By implementing new methods of assessment of lean meat content (EC 94
and EC 06), a higher share of meat (9.98% respectively 12.97%) was determined
compared to the Rulebook (1985). This research indicates the necessity of
changing the current method for the establishment of meat content of pigs in the
Republic of Serbia.

AB  - The aim of this study was to determine the influence of sire, sire within the breed, genotype, farm and age on variability of production traits of gilts tested: age at end of the test (AET), life daily gain (LDG), backfat thickness 1 and 2 (BFT1 and BFT2) and back muscle depth (MLD). The production traits of gilts were examined in two pig herds and for three consecutive years. The study included 3605 gilts of 3 genotypes, originating from 82 sire boars. The test included only those boar sires who had 10 or more daughters. In the first herd there were 1233 and in the second 2372 tested gilts. There were 1962 gilts of Landrace (L) breed, 1324 of Large White (LW) and 319 gilts of Duroc (D) breed. Total of 885 animals were tested in the first year, 1145 in the second and 1575 in the third year. Based on the obtained results, it was determined that the genotype had a statistically significant effect (P<0.001) on BFT1, BFT2 and MLD, while the AET and LDG traits were not influenced (P> 0.05). Considering the farm as a source of variation of gilts’ traits, it was concluded that it had a statistically very highly significant effect on the traits tested (P<0.001). The year of testing of gilts as a source of variation showed a very high statistical effect (P <0.001) on all traits examined. The sire breed statistically highly (P<0.001) led to the variation of the examined traits, which was also the case with the influence of the sires within the breed (P<0.001). The properties BFT1, BFT2 and MLD were highly statistically dependent (P <0.001) on weight at the end of the test.

AB  - Climate change and the emergence of new animal diseases emphasize the need to maintain and conserve plant and animal resources because of their adaptive capacity. For hundreds of millions of poor rural households, livestock produc-tion and crop farming are a key resource for life. Livestock production has great contribution and is vitally important for the life and safety of crop production. Conservation of animal genetic resources is not easy and simple, but it is of con-cern that in the past some animal genetic resources have been lost before their characterization and their genetic potential has not been studied. It is known that with the loss of a single breed or strain, the genetic diversity contained within also disappears. That is why it is necessary to continuously work on the conservation of animal genetic resources using various methods of conservation. The preservation and improvement of livestock production and animal genetic diversity, the preser-vation and the development of locally adapted (autochthonous) new breeds, as well as the preservation of genetically diverse populations provide society with a greater range of options to meet future challenges and further develop agriculture.

AB  - In the present study, the aim was to determine the impact of the following factors: age, farm, and gilt genotype, as well as the regression impact of body weight at the end of the performance test on the following tested properties: age at the end of the test/final age (FA), lifetime daily gain (LDG), the backfat thickness measured in two places (according to the Main Breeding program for Central Serbia), the depth of the long back muscle (BM) and the estimated lean meat content/meatiness (M). The study included two farms of pigs (farm 1 and farm 2), for three consecutive years (year 1, year 2 and year 3). The number of tested heads per year was 974 (year 1), 1311 (year 2) and 757 (year 3). The tested gilts were of Swedish Landrace, Large White and Duroc breeds. The gilts originated from 97 sires, while the number of daughters per sires ranged from 10 to 100. The results show that the Duroc animals were the oldest (245 days), which had the highest values for both measures of backfat thickness, but the lowest values for meatiness. In the third study year, the lowest average values were determined for the properties of the LDG, BM and M. The female animals from the farm 1 showed less growth/gain and had lower values for the estimated meatiness. As a result of the study, it was established that all included factors had a very high statistically significant influence on the variation of the tested properties (P <0.001), only the genotype of gilts showed ahigh statistically significant effect on the BM property (P <0.01).

AB  - : The aim of this paper was to determine the influence of sire
breed on meatiness of pig carcass. Trial was conducted on 480 pigs, offspring of
six boars, of two genotype Large White (LW) and Swedish Landrace (SL).
Average body mass of examined animals were 114.5 kg. Share of meat yield of pig
carcass was estimated on the slaughter line using two methods. First method use
“two point” system where first measurement is depth of m. longissimus measured
as the shortest link/connection between front (cranial) end of m. gluteus medius and
the top (dorsal) rim/edge of the spinal canal and second is where m. gluteus medius
penetrates the fat tissue the most. Second method also use two measurements: X1=
thickness of fat tissue (with skin) in millimeters measured on medial carcass
surface between 3rd and 4th lumbal vertebrae, caudo-cranially and X2=thickness
of fat tissue (with skin) in milimeters measured on medial carcass surface between
3rd and 4th rib, caudo-cranially. The meatiness of the progeny very significantly
depended on boar genotype (p<0.01). Offspring of SL boars had better results in
both methods (60.47; 56.45%), than LW offspring (60.35; 55.85%).
