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 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 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.

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  - 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  - The objective of this research was to determine whether a mass sperm motility in native ejaculate and a sperm dose-count (SDC) affect in vivo boar fertility. A total of 983 ejaculates taken from Landrace (n = 16 animals), Large White (n = 19 animals) and Duroc (n = 7 animals) breed boars were analyzed. The concentration of native sperm was assessed by means of a colorimeter, and the evaluation of mass sperm motility was performed by a subjective assessment using a microscope. On average, 20.70 doses for insemination were obtained per ejaculate and they were divided into three classes (SDC = ≤2.50; 2.51–4.00; ≥ 4.01 × 109). The insemination of 7661 breeding females was performed twice. The assessment of the effect was performed by means of a general linear model in the SAS 9.1.3 statistical package, using a model that includes a breed fixed effect and linear regression effect of motility nested within the class of sperm count in a dose. Average values of return rate (%), farrowing rate (%) and litter size at birth accounted for: 15.53%, 73.41% and 12.65 live piglets, respectively. All the traits of in vivo fertility varied under the effect of breed (p < 0.001). An increase in motility by one unit (%) resulted in a decreased percentage of return rate by 0.11% (p < 0.001) in all three SDC classes. On the other hand, the farrowing rate increased by 0.12–0.13% (p < 0.001) depending on SDC class. When litter size at birth is in question, a linear regression effect of motility was determined inside SDC with the highest sperm count (b = 0.01; p < 0.05).

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  - 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.

compositions of longissimus dorsi muscle in Moravka, an autochthonous pig breed of combined
production abilities. The trial conducted included 16 pigs: 7 entire males (EM) and 9 surgical
castrates (SC). The animals were bred in farm conditions in separate, group pens (110 m2 open and 40 m2 covered part). Pigs were fed ad libitum with complete feed mixtures: I (25-60 kg, 15% of
crude protein, and 13.6 MJ ME/kg) and II (60-120 kg, 13% of crude protein and 13.5 MJ ME/kg).
Muscle tissue chemical composition was determined by means of standard methods in an accredited laboratory. Fatty acids as methyl esters were determined using the capillary gas chromatography with a flame ionization detector. The effect evaluation was determined by means of a General Linear Model procedure in SAS 9.1.3 software, and besides castration treatment, the model included also a linear regression effect of body weight at slaughter (BW). An average pig BW was 121 kg at the age of 333 days. The increase of BW for 1 kg resulted in the increase of water content in muscle by 0.06% (p=0.040). The EM group had higher water content (+2.3%, p=0.047) and lower content of cholesterol (−15 mg/100 g, p=0.031). The same group had lower content of saturated (−3.6%, p=0.003) and mono-unsaturated (−5.6%, p<0.001), and a higher share of polyunsaturated (+9.0%, p<0.001) fatty acids compared to SC. From a nutritional aspect, the ratio of omega-6 and omega-3 essential fatty acids was more favorable in SC compared to the EM group (3.9 vs. 18.5, p<0.001). Castration had an effect on the quality of muscle tissue but regardless of some benefits determined in the EM group a main restricting factor for more massive fattening of non-castrated animals is a boar taint in the meat.

AB  - This work was aimed at evaluating loin transcriptome and metabolic pathway differences between the two main Serbian local pig breeds with divergent characteristics regarding muscle growth and fatness, as well as exploring nutrigenomic effects of tannin supplementation in Mangalitsa (MA) pigs. The study comprised 24 Mangalitsa and 10 Moravka (MO) males, which were kept under
identical management conditions. Mangalitsa animals were divided in two nutritional groups (n = 12) receiving a standard (control) or tannin–supplemented diet (1.5%; MAT). Moravka pigs were fed the standard mixture. All animals were slaughtered at a similar age; 120 kg of average live weight (LW) and loin tissue was used for RNA-seq analysis. Results showed 306 differentially expressed genes (DEGs) according to breed, enriched in genes involved in growth, lipid metabolism, protein metabolism and muscle development, such as PDK4, FABP4, MYOD1 and STAT3, as well as a relevant number of genes involved in mitochondrial respiratory activity (MT- Ds, NDUFAs among others). Oxidative phosphorylation was the most significantly affected pathway, activated in Mangalitsa muscle, revealing the basis of a different muscle metabolism. Also, many other relevant pathways were affected by breed and involved in oxidative stress response, fat accumulation and development of skeletal muscle. Results also allowed the identification of potential regulators and causal networks such as those controlled by FLCN, PPARGC1A or PRKAB1 with relevant regulatory roles on DEGs involved in mitochondrial and lipid metabolism, or IL3 and TRAF2 potentially controlling DEGs involved in muscle development. The Tannin effect on transcriptome was small, with only 23 DEGs, but included interesting ones involved in lipid deposition such as PPARGC1B. The results indicate a significant effect of the breed on muscle tissue gene expression, affecting relevant biological pathways and allowing the identification of strong regulatory candidate genes to underlie the gene expression and phenotypic differences between the compared groups.

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 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.

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 study included 201 offspring (108 castrated males and 93
females) of Landrace (L), Large White (LW) and Pietrain (P) sires. The studied
animals were of following genotype: Landrace (L; n = 48); two breed crosses with
50:50 share of parental breeds (LWxL, n=32; and PxL, n=23), two breed crosses
with 75% of paternal breed [Lx(♀LWxL), n=35] and [LWx(♀LxWL) n=38] and
three breed crosses [Px(♀LWxL) n=25]. Animals included in this study were born
during four seasons: winter (n=38), spring (n=65), summer (n=40) and autumn
(n=58). Studies have shown that, at an average weight of warm carcass side of
81.20 kg, the highest average values for the weight of round (RW; 10.204 kg), the
weight of intermuscular fatty tissue (RINT; 0.478 kg), bone tissue (RBT; 0.850 kg)
and muscle tissue (RMT, 7.552 kg) in the round, were established in three-breed
crosses of Px (LWxL) genotype compared to other genotypes. The least skin and
subcutaneous fatty tissue (RST; 1.269 kg) was recorded in two breed crosses PxL.
They had less skin and subcutaneous fatty tissue by 454 g and 467 grams,
respectively, compared to two breed crosses (LWxL) and LWx (♀LxLW).
Research has shown that there is a genotype on a farm that gives more muscle
tissue in the round by 1.521 kg [Px (♀LWxL): LWx (♀LWxL)] with the same
weight of warm carcass side, which is a very large difference. With the same
average weight of warm carcass side, female animals had higher average weight of
the round and yield of muscle tissue compared to male castrated animals. The
effect of genotype (P<0.001) on all investigated traits was recorded, also the effect
of the season of birth on the skin and subcutaneous fat tissue and on the weight of intermuscular fat in the round was recorded. The effect of sex/gender was significant (P<0.01) on the weight of skin and subcutaneous fat and on the weight of the muscle tissues in the round but no significant effect on other tested properties (P> 0.05) was observed.

AB  - The production characteristics of fatteners in this paper were examined in two farms of pigs in
the Republic of Serbia. The research included 1166 pigs of both genders (female animals and male castrated heads) with various genotypes. Research examined influence of sire breed, sire within sire breed, gender of the pigs and the mass at the end of the fattening on the following characteristics of the fatteners: daily gain of the warm carcass side mass (PTP), rump fat thickness (DSK), backfat thickness (DSL) and sum of the fat thickness rump+back (DSKL). The pigs in this research come from the following sires: Large White (LW), Swedish Landrace (SL), Duroc and Crossbreed H × D. Data processing was done using the Harvey computer program. It was determined that all the involved effects in the model show a different level of influence on the researched traits (P < 0.05; P < 0.01; P < 0.001), whereas only one factor, sire within sire breed H × D does not influence the expression of the characteristic gain of the warm carcass side mass (P > 0.05).

AB  - The objective of this research was to study the effect of immunocastration
on the morphometric characteristics of sex glands in male Swallow-bellied Mangalitsa
pigs. The study included 24 animals (13 entire and 11 immunocastrated males). The
research focused on the following traits: age at slaughter (days), live weight at slaughter
(kg), growth rate (kg day−1), and morphometric testicle traits (volume, cm3; weight, g;
length, width, thickness, and circumference, mm). The efficacy of immunocastration
was determined based on androstenone and skatole levels in adipose tissue. The
group of immunocastrated animals had higher body weight at slaughter (+18.8 kg)
due to higher average daily live gain (+87 g). Immunocastration resulted in reduced
morphometric measures of testes. The volumes and weight of testes/epididymes were
reduced by 28.9-54.4 and 32.1-53.3%, respectively. Testis length and other size-related
traits were significantly reduced by 17.4-27.6%. The linear regression effect of live body
weight at slaughter within the immunocastrated group on testis measurements was not
significant. Within the entire group of males, the increase of live body weight at slaughter
by 1 kg had an effect on the increase of volume and weight of testes/epididymes by
0.55-2.24 cm3 and 0.52-2.28 g, respectively. Other size-related testis traits increased
by 0.04-0.55 mm for each kg of body weight. Immunocastration also resulted in
79.6% decrease in the weight of accessory sex glands. The present study is the first to
demonstrate that immunocastration could be a method of choice for castration of the
local fatty pig breed, Mangulica (Swallow-bellied Mangalitsa).

AB  - Indigenous breeds of pigs are adapted to the specific areas in which they were created. In terms of scientific substantiation, their production potential and the products
obtained from them are, as in the case of Moravka pig, practically untapped. The main
objective of the present chapter is to present history and current status of this breed,
breeding area, its performance, production systems and main products from this local
breed of pigs. Reproductive traits were estimated by means of sow age at first farrowing,
litter size, weaning weight, duration of lactation and length of the farrowing interval.
Growth performance was estimated by means of average daily gain and average daily
feed intake in the early, middle, late and overall fattening stage. Carcass performance
was evaluated by means of slaughter weight, hot carcass weight, carcass yield, lean meat
content, loin eye area, the back fat thickness at the level of the last rib and withers and
the back fat and muscle thickness above the gluteus medius muscle. Meat quality traits of
the longissimus muscle were evaluated by means of pH at 45 min and 24 h after slaughter, objective colour (CIE L*, a* b*), intra muscular fat content and fatty acid content of
intramuscular fat.

investigated in the project TREASURE. Moreover, a collection and review of available
literature data, available until August 2017, on reproductive and productive traits of
Mangalitsa pig breed were carried out. Mangalitsa is a late and extremely fatty pig
breed with low fertility, long suckling period and a very weak-slow growth. Although
studies on Mangalitsa pig are scarce, the current review gives the first insight into this

AB  - Agro biodiversity or genetic resources for agriculture and food
is one of the most significant component of total biodiversity, and it encompasses
various animals, plants and micro-organisms that are necessary to maintain the key
functions of agro-ecosystems. According to the United Nations, the world
population has reached as much as 7.3 billion to date, with a forecast of 9.7 billion
in 2050 and 11 billion by the end of the century. Well-adapted and well-developed
livestock farming is an essential element of the agricultural production system,
especially important in difficult conditions when crop production in the agroecosystem cannot sustain and increase its productivity and adapt to changing
circumstances, and is crucial for the food security of the population. Preservation
and improvement of livestock farming, animal genetic diversity, preservation of
autochthonous and development of new breeds, preservation of genetically diverse
populations provide society with a greater range of options to meet the future
challenges in the development of agriculture. This paper gives review of the
condition of farm animals and autochthonous breeds: Podolian bovine, Busha,
domestic buffalo, domestic-mountain horse, Nonius, Balkan donkey, Mangalitsa,
Moravka, and Resavka pig, Pirot sheep, Bardoka, Krivovir sheep, Karakachan
sheep, Lipska sheep, Vlaška-Vitoroga sheep, Čokan Tsigai goat, Balkan goat,
Svrljig hen, Banat Naked Neck hen and Sombor Kaporka hen. Genetic resources in
animal husbandry represent all species, breeds and strains of farm animals and they
have economic, scientific and cultural significance for our country.

AB  - The main objective of this paper is to present the results of the research of the Swallow belly Mangalitsa genotype in the last six decades. According to the research, females reach the full maturity the age of 9-10 months, but they are mated at the age of 1-1.5 years. Average age at first farrowing is 556 days. Reproductive ability is poorly expressed, with a strong maternal instinct. Fertility of the Mangalitsa is relatively poor because it gives birth to 1-12 piglets, on average 4 to 5 piglets, with an average body weight of 1.25 kg with a variation of 0.8 to 1.8 kg. The suckling period is about 50 days (from 47 to 53 days). At lactation duration of 60 days, the piglet weight at the weaning ranges from 6-13 kg (average 9.61 kg) for piglets born in the spring, and from 7-15 kg (average 9.50 kg) for piglets born in fall. Depending on the rearing system, the start of fattening and final body weight, gains range 268 g to 830 g. The fat thickness (average measurements) at the ridge was 10.2 cm, the middle of the back 7.9 cm and the rump 8.1 cm, in previous studies, while in recent studies these values of fat thickness are somewhat lower, with the pre-slaughter body weight also being lower (the ridge 6.18 cm, the middle of the back 4.38 cm and at the rump 5.19 cm). The recent research of the Longissimus dorsi muscle shows an intramuscular fat content of 13.5%, protein content of 21.1% with specific qualitative properties pH45=6.11; pH24=5.50; CIE L*=40.13; a*=11.77; b*=3.73). In the musculus longissimus lumborum and thoracis, Mangalitsa (Swallow-bellied) pigs show higher levels of monounsaturated fatty acids (MUFA 55.1%) and lower levels of saturated fatty acids (SFA 35.3%) in comparison with Swedish Landrace pigs.

Fertility of the Mangalitsa is relatively poor because it gives birth to 1-12 piglets, on average 4 to 5 piglets, with an average body weight of 1.25 kg with a variation of 0.8 to 1.8 kg. The suckling period is about 50 days (from 47 to 53 days). At lactation duration of 60 days, the piglet weight at the weaning ranges from 6-13 kg (average 9.61 kg) for piglets born in the spring, and from 7-15 kg (average 9.50 kg) for piglets born in fall. Depending on the rearing system, the start of fattening and final body weight, gains range 268 g to 830 g. The fat thickness (average measurements) at the ridge was 10.2 cm, the middle of the back 7.9 cm and the rump 8.1 cm, in previous studies, while in recent studies these values of fat thickness are somewhat lower, with the pre-slaughter body weight also being lower (the ridge 6.18 cm, the middle of the back 4.38 cm and at the rump 5.19 cm). The recent research of the Longissimus dorsi muscle shows an intramuscular fat content of 13.5%, protein content of 21.1% with specific qualitative properties pH45=6.11; pH24=5.50; CIE L*=40.13; a*=11.77; b*=3.73). In the musculus longissimus lumborum and thoracis, Mangalitsa (Swallow-bellied) pigs show higher levels of monounsaturated fatty acids (MUFA 55.1%) and lower levels of saturated fatty acids (SFA 35.3%) in comparison with Swedish Landrace pigs.",

AB  - The main objective of this paper is to present characteristics of autochthonous pig breed Moravka, reared in the previous century, as well as results of investigations of production performance in the last ten years. A collection of available literature data on reproductive, growth, carcass and meat quality traits of Moravka breed was carried out. According to research studies done in the 50-ies of the last century, Moravka females reached sexual maturity at about 5-6 month, whereas breeding maturity was at age of 10-12 months. Average litter size (different parities) was 6.8-8.2 born alive piglets (1.2 kg birth weight). Lactation lasted around 60 days. At weaning piglets weighed 8.7-10.4 kg (i.e. 120-150 g daily gain). Recent studies show that in average the age at first farrowing was 373±10 days, litter size 8.6±1.7 born piglets, and duration of lactation 46.8±3.4 days. Regarding growing/fattening results, only one of old studies reported daily gain in growing phase which was in average 186-197 g (depending of sex), whereas depending on type of feeding and season daily gain for fattening phase was reported between 490 and 660 g (for pigs on feed mixture and intake between 2.5 to 3.2 kg). Reported feed conversion ratio was from 4.4 to 5.1 kg/kg feed mixtures. A more recent research reported piglets to have 31.9 kg at 192 days denoting a growth rate of about 160 g/day in growing phase, whereas pigs fattened from 32 to 94 kg with maize grew 385 g/day (reported feed conversion ratio was 3.74). Backfat thickness (average of measurements along split line) was app. 7 cm (from about 4 to 9 cm) in earlier and app. 4 cm (from about 3 to 6 cm) in recent studies, but it must be noted that slaughter weight was considerably lower in recent studies. The newest research on Longissimus dorsi muscle showed intramuscular fat content of 7.0±0.6%, 21.5±0.2% of proteins with the specific quality traits (pH45=6.53±0.13, pH24=5.65±0.05; CIE L*=48.9±1.4, a*=12.0±1.0, b*=5.9±0.4).

AB  - Extremely rich genetic funds of animals obtained by natural selection through the centuries are very important resources of Serbia. In Serbia, surgical castration of male animals in first week post partum is a usual practice to avoid boar taint. Considering that Mangalitsa sows are good mothers and most aggressively protect the piglets we tested the alternative to physical castration. The aim of this study was to examine the effect of method of castration (physical or immunocastration) on growth potential of indigenous pig breed Mangalitsa Swallow Bellied. Investigation included surgically castrated (SC; n=12) and immunocastrated (IC; n=11) male pigs, fed ad libitum a feed mixture with 12-13 MJ ME/kg; 13-15% crude protein (two-phase feeding). The experiment started at 24.4 weeks of age when average body  weight (ABW) of SC pigs was 24.3 kg and of IC pigs 28.4 kg. Immunocastrates were vaccinated with Improvac® (Zoetis-Pfizer) at 39 (V1) and revacinated at 46 (V2) weeks of age (WA). Pigs were slaughtered 6 weeks after V2. Until V1 when IC are actually entire males, growth rate was slightly lower in IC than SC pigs (446 vs. 495 g/day, respectively).  Established difference was statistically significant (P=0.03). In the period between V1 and V2 growth rate was alike in IC and SC (454 vs. 448 g/day, respectively; P=0.92). Overalluntil V2, there was no difference in ABW between IC and SC pigs (99.2 vs. 100.2, respectively; P=0.89). The maximal growth rate (689 vs. 683 g/d for SC and IC, respectively) was observed between 35 and 39 WA. In the period after V2 until the end of the fattening period growth rate was significantly higher (P=0.002) in IC than SC pigs (548 g vs. 392 g, respectively) in agreement with higher feed intake of IC than SC (3.2 vs. 2.7 kg/pig/day recorded on a pen basis). Present results on the indigenous Mangalitsa breed confirm what has been previously demonstrated in modern breeds, i.e. that after the effective immunisation the pigs increase their feed intake and consequently growth rate.
