AB  - 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  - 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‐NDs, 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 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 lt 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.

Za određivanje prinosa mesa (JUS1) i udela mesa (JUS 2) u polutkama, na osnovu izvršenih merenja, korićene su tabele za mesnate svinje, koji su sastavni deo Pravilnika o kvalitetu zaklanih svinja i kategorizaciji svinjskog mesa (SG SFRJ, 1985). Udeo mesa (EC 94 i EC 06) određen je na ohlađenim levim polutkama metodom delimične sekcije (prema metodologiji preporučenoj od strane EU - Walstra i Merkus, 1996). Istraživanje je sprovedeno na svinjarskoj farmi i u eksperimentalnoj klanici Instituta za stočarstvo Beograd-Zemun. Smeštaj, nega i ishrana životinja bili su u skladu sa tehnologijom uzgoja u ispitivanom zapatu. Prosečan udeo mesa utvrđen primenom Pravilnika (JUS2) iznosio je 43,58% sa nižom apsolutnom varijacijom u poređenju sa uredbom EU iz 1994. (EC 94; 53,56%) i iz 2006 (EC 06; 56,55%). Procenjeni sadržaj mesa primenom Pravilnika (JUS 2) bio je za 9,98% niži u odnosu na uredbu EC 94 i za 12,97% niži u odnosu na EC 06. Ako govorimo o izboru potomstva za uzgoj, ako uzmemo u obzir samo procenjenu mesnatost, vidimo da unutar rase L imamo visoke i veoma značajne (P  lt 0,001) razlike između očeva za procenjeni sadržaj mesa u skladu sa EC 94 i EC 06. Implementacijom novih metoda procene sadržaja mesa (EC 94 i EC 06), utvrđen je veći udeo mesa (9,98%, odnosno 12,97%) u poređenju sa Pravilnikom (1985).

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 lt 0.01; p lt 0.001). Weight at the end of the test (p lt 0.05; p lt 0.01; p lt 0.001) affected all examined traits, except CON and TNS. A weak association was found between production performance and ejaculate traits.
AB  - Osnovni cilj istraživanja bio je da se utvrdi uticaj rase na osobine ejakulata nerasta: volumen ejakulata (VOL, ml), koncentracija sperme (CON, x106 spermatozoida/ml), ukupan broj spermatozoida u ejakulatu (TNS, x109 spermatozoida) pokretljivost spermatozoida u nativnom ejakulatu (MON, %), pokretljivost spermatozoida nakon razreĊenja (MOD, %) i broj proizvedenih doza (NPD). Cilj je bio i da se oceni povezanost osobina iz performans testa nerasta: proseĉan životni dnevni prirast (g), debljina slanine merena na dva mesta (mm), dubina dugog leĊnog mišića (mm) i sadržaj mesa u trupu (%) sa osobinama ejakulata. Analiziran je 931 ejakulat od 36 nerasta tokom reproduktivne eksploatacije (16 nerasta landrasa i 20 nerasta velikog jorkšira). Procena uticaja izvršena je primenom procedure opšteg linearnog modela statistiĉkog paketa SAS 9.1.3 (SAS Inst. Inc., 2002-2003). Model za analizu obuhvatao je uticaj rase, sezone i linearni regresijski uticaj telesne mase na kraju performans testa. Povezanost osobina utvrĊena je primenom Pirsonovog koeficijenta korelacije. Većina ispitivanih osobina ejakulata (VOL, CON, MOD i NPD) varirala je pod uticajem rase nerasta (p lt 0,01; p lt 0,001). Masa na kraju testa (p lt 0,05; p lt 0,01; p lt 0,001) uticala je na sve ispitivane osobine, osim na CON i TNS. IzmeĊu proizvodnih performansi i osobina ejakulata utvrĊena je slaba povezanost.

A weak association was found between production performance and ejaculate traits., Osnovni cilj istraživanja bio je da se utvrdi uticaj rase na osobine ejakulata nerasta: volumen ejakulata (VOL, ml), koncentracija sperme (CON, x106 spermatozoida/ml), ukupan broj spermatozoida u ejakulatu (TNS, x109 spermatozoida) pokretljivost spermatozoida u nativnom ejakulatu (MON, %), pokretljivost spermatozoida nakon razreĊenja (MOD, %) i broj proizvedenih doza (NPD). Cilj je bio i da se oceni povezanost osobina iz performans testa nerasta: proseĉan životni dnevni prirast (g), debljina slanine merena na dva mesta (mm), dubina dugog leĊnog mišića (mm) i sadržaj mesa u trupu (%) sa osobinama ejakulata. Analiziran je 931 ejakulat od 36 nerasta tokom reproduktivne eksploatacije (16 nerasta landrasa i 20 nerasta velikog jorkšira). Procena uticaja izvršena je primenom procedure opšteg linearnog modela statistiĉkog paketa SAS 9.1.3 (SAS Inst. Inc., 2002-2003). Model za analizu obuhvatao je uticaj rase, sezone i linearni regresijski uticaj telesne mase na kraju performans testa. Povezanost osobina utvrĊena je primenom Pirsonovog koeficijenta korelacije. Većina ispitivanih osobina ejakulata (VOL, CON, MOD i NPD) varirala je pod uticajem rase nerasta (p lt 0,01; p lt 0,001). Masa na kraju testa (p lt 0,05; p lt 0,01; p lt 0,001) uticala je na sve ispitivane osobine, osim na CON i TNS. IzmeĊu proizvodnih performansi i osobina ejakulata utvrĊena je slaba povezanost.",

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  lt 0.001), only the genotype of gilts showed ahigh statistically significant effect on the BM property (P  lt 0.01).

Nazimice potiču od 97 očeva, dok je broj kćeri po očevima iznosio od 10 do 100. Rezultati pokazuju da su najstarija grla rase Duroc (245 dana), koja imaju i najveće vrednosti za obe mere debljine slanine, ali najmanje vrednosti za mesnatost. U trećoj godini ispitivanja najmanje prosečne vrednosti su utvrđene za osobine LDG, BM i M. Ženska grla sa farme 1 su slabije prirastala i imala manje vrednosti za procenjenu mesnatost. Kao rezultat ispitivanja utvrđeno je da su svi uključeni faktori veoma visoko statistički značajno uticali na variranje ispitivanih osobina (P  lt 0.001), jedino genotip nazimica pokazuje visok statistički značajan uticaj na osobinu BM (P lt 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 lt 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 lt 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.

Najmanje kože i potkožnog masnog tkiva (RST; 1,269 kg) zabeleženo je kod dvorasnih meleza PxL. Imali su manje kože i potkožnog masnog tkiva za 454 g, odnosno 467 grama, u poređenju sa dvorasnim melezima (LWxL) i LWx (♀LxLW). Istraživanja su pokazala da na farmi postoji genotip koji daje više mišićnog tkiva u butu za 1.521 kg [Px (♀LWxL): LWx (♀LWxL)] sa istom masom tople polutke, što je vrlo velika razlika.

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  lt  0.05; P  lt  0.01; P  lt  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, cm(3); 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 cm(3) 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  - The share of variance components and correlations between the most important sow production traits (namely duration of fattening - DF, backfat thickness - BF and number of liveborn piglets - NBA) included in the pig breeding selection programme of the Republic of Serbia were estimated in this paper. The litter size at repeated farrowings (NBA1,..., NBA6) was treated as a separate trait (the multi-trait model), whereas the litter size at birth was treated as a trait repeated a number of times (the repeatability model)). The estimation of dispersion parameters was performed using the Restricted Maximum Likelihood (REML) method. The heritability of DF accounted for 23.5%, i.e. 23.3% depending on the model used, whereas BF accounted for 40.4% in both cases. The heritability of the litter size in consecutive farrowings (the multi-trait model) were in intervals ranging between 0.104 (NBA1) and 0.136 (NBA5). The heritability of NBA in the repeatability treatment accounted for 0.106, whereas the common litter environment and the permanent sow influence contributed to the total variability with 1.1% and 5.6%, respectively. Genetic correlations between the traits examined were not determined, with the exception of consecutive farrowings in the multi-trait treatment of the litter size. The genetic correlations recorded in this case proved positive and complete, with the exception of the correlation between the first and subsequent farrowings (farrowings 3 to 6) and the correlation between the second and the last farrowings (farrowings 5 and 6), which proved very strong.

AB  - The study included the progeny of three boar-sires breeds (SL-Swedish Landrace; LW-Large White and P-Pietrain). A total of 201 progeny of both sexes (93 female and 108 male castrated animals), originating from 16 boar-sires, were tested. The study included the progeny of 10 SL boar-sires (sires nuRWer: 1, 2, 3, 7, 8, 9, 15, 16, 17 and 18), progeny of 3 LW sires (sires nuRWer: 4, 5 and 6) and 3 P boar-sires (sires nuRWer 14, 19 and 20), born in four seasons (winter, spring, summer and autumn). Studies have shown that, with an mean weight of a warm carcass side of 81.20 kg, the highest mean values for ham weight (RW; 10.456 kg), mass of intermuscular fatty tissue (RINT; 0.477 kg), ham bone (RB; 0.837 kg) and muscle tissue RMT, 7,939 kg) have progeny of the sires of Pietrain breed (P) compared to SL and LW sires. In comparison to animals sired by SL and LW boars, the progeny of P sires had less skin and subcutaneous fat tissue (RSFT) by 30 and 549 grams. Studies have shown that we have progeny of sires 7 and 9 of SL breed which have the lowest LSMean values for the yield of skin and subcutaneous fat tissue (869 and 876 g), which is below the mean for breed by 364 and 357 g. In addition, when it comes to intermuscular fatty tissue, the lowest established value was recorded in the progeny of sire no. 8 of SL breed (182 g), which is by 220 g less than the general mean and by 132 g below the mean of the sire breed. The animals originating from sires n. 19 and 20 showed the highest weight of muscle tissue (RMT) (8.489 and 8.118 kg) in the ham, which is by 2.853 and 2.482 kg more meat compared to the progeny of sire no. 5 of LW breed. The total weight of the ham and the ham muscle yield were influenced by (P  lt 0.01 and P  lt 0.001) sire breed, sires within the breed, gender and season of birth. A very significant (P  lt 0.001) influence of the weight of warm carcass sides on the ham weight and tissue yield was determined.

AB  - The effect of breed, gender and the farrowing season on the variability of pork quality traits was examined in the present study. The observed properties were the pH value (pH45 and pH24) of the Longissimus dorsi muscle (LD) and Semimembranosus muscle (SM), the chemical composition (water, fat, ash and protein content), the water binding capacity, the colour and thickness of the LD fibres. In the present study, the influence (P lt  0.05) of the farrowing season for both measured pH values in SM was established, as well as significant influence (P lt  0.01) on pH24 in LD, while the other factors did not influence the pH of the muscles tested. The established difference in the mean values of water content in LD between fatteners SW and LWxSL (0.69%) was statistically very significant (P lt  0.001) while the influence of genotype and sex of fatteners was not determined for fat, ash and protein content. The genotype of fatteners influenced the ability to bind water (P lt  0.001) and the meat colour (P lt  0.05) while the muscle thickness was not affected (P> 0.05).

The genotype of fatteners influenced the ability to bind water (P lt  0.001) and the meat colour (P lt  0.05) while the muscle thickness was not affected (P> 0.05).",

AB  - Objective of this paper was to evaluate phenotypic variability of fertility traits of indigenous breeds of Mangalitsa (Swallow-Belly Strain Mangalitsa-SBSM), Moravka breed (M) and Resavka (R). Indigenous pig populations are usually constituted by a quite low number of active boars and sows. Their pedigree information is lacking or absent, complete phenotypic description is usually not available for most of these populations that are very well adapted to specific local agro-climatic environments. In controlled herds in period of four years, the average age at first farrowing (AFF) was 18.5 months with large variability of 5.9 months for Swallow belly Mangalitsa. Less AFF (14.3 months) and less variability (4.4 months), in relation to SBSM, determined for Moravka breed while for Resavka determined age of 14.7 months with at least variability for this trait from 4.4 months. The average number of piglets born alive (for a period of four years) of SBSM was the lowest from 4.37 to 4.81; in case of M and R, this value was significantly (P lt 0.001) higher (from 5.75 to 8.17 and for R breed 6.40 to 9.00). With average duration of suckling period (duration of lactation - DL) of 52.92 days in the first year for the breed SBSM with the lowest number of reared piglets (NRP=4.10) whereas the DL for M and R breeds was shorter (from 45.75 to 52.03 day) with a higher NRP (from 4.57 to 8.92 reared piglets).
AB  - Cilj ovog rada je bio da se utvrdi fenotipska varijabilnost osobina plodnosti autohtonih rasa mangulice (lasasta mangulica-SBSM), moravke (M) i resavke (R). Autohtone populacije svinja obično čini prilično mali broj aktivnih nerasta i krmača. Informacije o poreklu često nedostaju ili su nedostupne, kompletan fenotipski opis obično nije dostupan za većinu ovih populacija koje su vrlo dobro prilagođene specifičnim lokalnim agro-klimatskim uslovima. Kod kontrolisanih zapata, u periodu od četiri godine, prosečan uzrast pri prvom prašenju (AFF) iznosio je 18,5 meseci sa velikom varijacijom od 5,9 meseci kod lasaste mangulice. Manje vrednosti AFF (14,3 meseca) i manja varijabilnost (4,4 meseca), u odnosu na SBSM, utvrđen je za moravku, dok je za resavku utvrđen uzrast od 14,7 meseca sa najmanjom varijabilnošću za ovu osobinu od 4,4 meseca. Prosečan broj živo rođene prasadi (u trajanju od četiri godine) kod SBSM, je bio najniži od 4,37 do 4,81; kod svinja M i R, ova vrednost je značajno (P  lt 0,001) viša (od 5,75 do 8,17 i 6,40 do 9,00 respektivno). Prosečno trajanje perioda sisanja (trajanje laktacije - DL) od 52,92 dana u prvoj godini za rasu SBSM, sa najnižim brojem odgajenih prasadi (NRP = 4,10), dok je DL za M i R rase kraći (45,75 i 52,03 respektivno) sa većom vrednošću NRP (od 4,57 do 8,92 odgajanih prasadi).

AB  - The most important part in reproductive management is the control of boar fertility. A common division of fertility traits is on the: in vitro (sperm traits) and in vivo (return rate, farrowing rate and litter size traits) fertility. In many studies were found differences between breed in the both groups of fertility traits. Variability of sperm traits of boars during the reproductive exploitation is influenced by various genetic (boar, breed) and paragenetic factors/effects (age, season, intensity of use). Good libido is desirable characteristics in boars, but the knowledge of the correlation of libido and boar fertility traits are limited. Also, there is no standardised procedure or methods for the estimation of libido of the boars. The permanent ranking of boars according to the reproductive efficiency should be performing. Good reproductive management implies the timely identification of boars with the low fertility (or close to the average).

AB  - Objective of this paper was to evalutte phenotypic variability of carcass side and pork quality traits of fatteners (male castrated and female heads). Investigation included 12 pigs per group of Mangalitsa (Genotype 1), Moravka (Genotype 2), cross-breed Mangalitsa with Moravka (Genotype 3) and cross-breed Moravka with Duroc boar (Genotype 4). Results show that Mangalitsa had lower daily gain (268 g) than other genotypes (p lt 0.001). The greatest difference for fat thickness was determined between Genotype 1 and Genotype 4. As expected, the thinnest fat and maximum value for gain and depth of Musculus longissimus (ML) had the Genotype 4. The highest value for the ML surface was found in Genotype 4(47.52 cm(2)) whereas for the same trait in Mangalitsa the lowest value was observed (24.16 cm(2)). Mangalitsa had significantly lower L*, a* and b* values of ML compared with all other groups (p lt 0.001). Considering the low production performance of indigenous pig breeds, crossbreeding with the Duroc breed will contribute a improvement of growth and carcass traits.

AB  - Heredity and correlation of litter size traits were observed in 3693 litters, i.e. in 1622 daughters of two genotypes Swedish Landrace genotype - SL; and F1 ♀ SLxLW. The study included daughters (minimum ten daughters per sire) of 24 sires. Heritability estimates for the total number of piglets per litter in the first, the first two parities, and for all three parities was 0.174; 0.167 and 0.135. Heritability estimates for the number of piglets born alive were 0.181; 0.160 and 0.121, and for the weight of litter at birth 0.166; 0.174 and 0.150. On the other hand, very low heritability was determined for the number of weaned piglets, litter weight of piglets reared, individual weight of born and reared piglets, i.e. for the traits that are under greater influence of the environment (from 0.004 to 0.037). Phenotypic and genetic correlations ranged from weak to complete (rp = 0.021 to rp = 0.973 and rg=0.188 to rg=0.999, respectively). Analysis of the significance of correlations showed that the genetic correlations were statistically highly significant (P  lt 0.01).

AB  - The main objective of this study was to assess the variability of ejaculate properties: volume of ejaculate (VOL, ml), sperm concentration (CON, spermatozoa/ml), total sperm count (NT) and the number of doses produced (NPD) per ejaculate under the influence of season, boar and the interval between two mounts. Reproductive efficiency of boars was analysed based on the farrowing rate (FR). The study included 341 ejaculates from seven Large White boars. Impact assessment was carried out by applying the GLM procedure of the statistical package SAS 9.1.3. The average values of VOL, CON, NT, NPD and FR were: 244.28 ml, 203.77x106 spermatozoa/ml, 43.48x109 spermatozoa, 17.39 doses and 67.58%. Ejaculate properties varied under the influence of season (P lt 0.01, P lt 0.001). The interval between two mounts did not affect only the variability of CON. The difference between the best and worst boars was 91.99x106 spermatozoa/ml of ejaculate (P lt 0.001). During summer VOL ejaculate was the lowest (191.36 ml). The highest NPD (19.04 doses) was produced during the autumn months, and during the same period the highest concentration of sperm was recorded (242.16x106 spermatozoa/ml). Regardless of the differences in the farrowing rate between boars not being statistically significant (P=0.0882), it is necessary to perform the ranking and promptly identify boars with farrowing rate below average.
AB  - Osnovni cilj istraživanja bio je da se oceni varijabilnost osobina ejakulata: volumen ejakulata(VOL, ml), koncentracija sperme (CON, spermatozoida/ml), ukupan broj spermatozoida (NT) i broj proizvedenih doza (NPD) po ejakulatu pod uticajem nerasta, sezone i intervala izmedju dva skoka. Reproduktivna efikasnost nerasta analizirana je na osnovu procenta prašenja (FR). Istraživanjem je bio obuhvaćen 341 ejakulat sedam nerasta velikog jorkšira. Ocena uticaja je izvršena primenom GLM procedure u statističkom paketu SAS 9.1.3. Prosečne vrednosti VOL, CON, NT, NPD i FR bile su: 244,28 ml, 203,77x106 spermatozoida/ml, 43,48x109 spermatozoida, 17,39 doza i 67,58%. Osobine ejakulata varirale su pod uticajem sezone (P lt 0,01; P lt 0,001). Interval između dva skoka nije uticao jedino na varijabilnost CON. Razlika izmedju najboljeg i najlošijeg nerasta bila je 91,99x106 spermatozoida/ml ejakulata (P lt 0,001). Tokom letnjih meseci VOL ejakulata bio je najmanji (191,36 ml). Najveći NPD (19,04 doza) proizveden je tokom jesenjih meseci, a tokom istog perioda bila je i najveća koncentracija sperme (242,16x106 spermatozoida/ml). Bez obzira što razlike u procentu prašenja između nerasta nisu bile statistički značajne (P=0,0882), potrebno je vršiti rangiranje i pravovremeno identifikovati neraste sa procentom prašenja ispod proseka.

AB  - The study was conducted on 700 fattening pigs, three breed half blood with Duroc as a terminal breed ((Large White x Landrace) x Duroc). The pigs were divided into the  two groups according to diet: dry and liquid nutrition. Each group consisted of 350 fattening pigs and used the same feed mixtures in prefattening (CP-3) and fattening (ST). During the period from 24.8 to 60kg they were fed with a CP-3, a crude protein content of 16.37%. During the period from 60kg until the end they were fed with ST, a crude protein content of 15.3%. Muscle tissue processed half-carcasses in slaughterhouses were determined by a device that determines the value of S (fat thickness) and M (muscle thickness) using "method one point." Fat thickness skin in mm, measured 7 cm lateral to the central (median) cutting, in the amount between the second and third ribs of the tail. The thickness of the muscle in mm was measured at the same place as the thickness of the bacon. The results show that the fatling fed dry food had significantly higher carcass weight (80.41: 78.51 kg, p lt 0.05), backfat thickness (16.55: 15.31 mm, p lt 0.05), weight (muscle 55.80: 53.82, p lt 0.05), but a lower percentage of meat (56.6: 57.3, p lt 0.05) as compared to pigs fed liquid food. In finishing pigs fed dry food, between carcass weight and backfat thickness and muscle thickness a positive and significant correlation (0.4267 and 0.4290, p lt 0.05) was found and between carcass weight and lean meat a significant negative correlation (-0. 4236 and p lt 0.05). Between backfat thickness and lean meat in the carcass a negative and significant correlation (-0.8534, p lt 0.05) was found and between muscle thickness and lean meat a positive and significant correlation (0.2857, p lt 0.05). In finishing pigs fed liquid food, between carcass weight and backfat thickness and muscle thickness a positive and significant correlation (0.1800 and 0.3705, p lt 0.05) was found and between carcass weight and lean meat a significant negative correlation (-0. 2178; p  lt 0.05). Between backfat thickness and percentage of meat in the carcass negative and significant correlation (-0.8692, p lt 0.05) was found and between muscle thickness and lean meat a positive and significant correlation (0.3168, p lt 0.05).

AB  - The goal of this research paper was to assess the breeding value of first farrowed Swedish Landrace sows by the means of selection indices method. The traits on the basis of which the breeding value of animals was assessed are following: daily  liveweight gain, average thickness of collected back fat measured at five sites and number of liveborn piglets in the first litter. The liveweight gain and carcass quality traits determined at the end of performance test were corrected for the body mass of 100kg by the method of basic indexes and following mean values were determined: for corrected daily liveweight gain (KZDP) 499.92g/day and for corrected average collected backfat thickness (KSL) 20.01mm. The first farrowed sows on average produced 8.09 liveborn piglets in the litter. Studying the effect of the gilts` birth year and season on KZDP and KSL it was determined that the gilts` birth year and season had no statistically significant influence (P>0.05) on KZDP variation but they had a statistically significant effect on KSL (P lt 0.01). The year and the season of farrowing and the class of backfat thickness in performance test did not display any statistically significant effect (P>0.05) on BZPL, while the KZDP class and the age at first farrowing had a statistically significant effect on the variability of these trait (P lt 0.05; P lt 0.01). All studied traits varied statistically significantly (P lt 0.01) under the impact of the gilts` sire or dam. Heritability coefficients were: h2= 0.402 for KZDP, h2= 0.261 for KSL and h2= 0.177 for BZPL. The relation between KZDP and KSL was of a medium strength both at phenotype and genetic levels (rph=0.491; rg=0.411), while the relation of these traits with BZPL did not exist, except for the genetic relationship between KSL and KZDP which was of a medium strength (rg=0.252). Three equations for the selection indexes were constructed among which as the most optimal was chosen the one which includes all three traits (KZDP, KSL and BZPL) and whose correlation coefficent of selection index and aggregate  genotype was rIAG = 0.5473.

AB  - The aim of this study was to evaluate the chemical composition of the back fat tissue of mangalitsa pig and meaty pig breeds and their crosses, and the pigs that were fed with feed that was enriched or unenriched with oil, from the aspect of the production of biodiesel, where the starting material for the fuel would be the fat tissue of pigs. By examining the impact of breed and oil content in feed, it was found that chemical parameters (fat, water, protein, saturated and unsaturated fatty acids) show statistically significant variation under the influence of these factors. The highest fat content (89.39%), which is essential for conversion of fat into biodiesel, was found in back adipose tissue of mangalitsa breed, while the lowest fat content (86.10%) was found in the back fat tissue of meaty breeds and their crosses. Favorable ratio of saturated to unsaturated fatty acids (37.92% : 62.07%), on which some physical properties of the fuel depend, was found in the back fat tissue of pigs that were fed with feed enriched with oil, and the largest proportion of saturated fatty acids, i.e. the most unfavorable fatty acid composition (40.90% : 59.09%) was found in the back fat tissues of pigs that were fed with feed unenriched with oil. The lowest content of saturated fatty acids and water (7.44%), as the key factors that determine the cetane number of the fuel and the fuel production process, indicates that the most suitable raw material for the production of biodiesel is the fat tissue of pigs that were fed with food that contained a certain amount of oil.
AB  - Cilj rada bio je da se ispita hemijski sastav leđnog masnog tkiva svinja rase mangulica i plemenitih mesnatih rasa i njihovih meleza, kao i svinja koje su hranjene hranom obogaćenom ili neobogaćenom uljem, a sve sa aspekta proizvodnje biodizela gde bi polazna sirovina za ovo gorivo bilo masno tkivo svinja. Ispitujući uticaj rase i sadržaja ulja u hrani ustanovljeno je statistički značajno variranje hemijskih karakteristika masnog tkiva svinja (sadržaja masti, vode, proteina, zasićenih i nezasićenih masnih kiselina) pod uticajem ovih faktora. Najveći sadržaj masti (89,39%) koji je ključni faktor konverzije sirovine u biodizel utvrđen je u leđnom masnom tkivu rase mangulica dok je najmanji sadržaj masti (86,10%) utvrđen u leđnoj slanini plemenitih mesnatih rasa i njihovih meleza. Najpovoljniji odnos zasićenih i nezasićenih masnih kiselina (37,92% : 62,07%) koje uslovljavaju neke fizičke osobine goriva utvrđen je u leđnoj slanini grla čija je hrana bila obogaćena uljem, a najveći udeo zasićenih masnih kiselina, odnosno najnepovoljniji masnokiselinski sastav (40,90% : 59,09%) utvrđen je u masnom tkivu grla koja su dobijala hranu siromašnu uljem. Najmanji sadržaj zasićenih masnih kiselina i vode (7,44%) kao ključnih faktora od kojih zavise cetanski broj i proces proizvodnje goriva ukazuje da je najpogodnija sirovina za proizvodnju biodizela masno tkivo grla čija je hrana sadržala određenu količinu ulja.

abstract = "The aim of this study was to evaluate the chemical composition of the back fat tissue of mangalitsa pig and meaty pig breeds and their crosses, and the pigs that were fed with feed that was enriched or unenriched with oil, from the aspect of the production of biodiesel, where the starting material for the fuel would be the fat tissue of pigs. By examining the impact of breed and oil content in feed, it was found that chemical parameters (fat, water, protein, saturated and unsaturated fatty acids) show statistically significant variation under the influence of these factors. The highest fat content (89.39%), which is essential for conversion of fat into biodiesel, was found in back adipose tissue of mangalitsa breed, while the lowest fat content (86.10%) was found in the back fat tissue of meaty breeds and their crosses. Favorable ratio of saturated to unsaturated fatty acids (37.92% : 62.07%), on which some physical properties of the fuel depend, was found in the back fat tissue of pigs that were fed with feed enriched with oil, and the largest proportion of saturated fatty acids, i.e. the most unfavorable fatty acid composition (40.90% : 59.09%) was found in the back fat tissues of pigs that were fed with feed unenriched with oil.

AB  - Variance components for sow litter size traits were estimated using the REML method. Number of live born piglets (NBA), number of still born piglets (NSB), number of total born piglets (NTB) and number of weaned piglets (NW) were treated as traits which repeated several times during sow lifetime - repeatability model. Results of the fertility of Swedish Landrace sows realized on three pig farms in the Republic of Serbia were presented in four data sets DS1 (farm 1), DS2 (farm 2), DS3 (farm 3) and DS23 (farms 2 and 3 together). Fixed part of the model for litter size traits at farrowing (NBA, NSB and NTB) included parity, mating season as year-month interaction, litter genotype and weaning to conception interval as class effects. The age at farrowing was modelled as a quadratic regression nested within parity, whereas preceding lactation length was included as linear regression.  In case of NW the model included parity, weaning season as year-month interaction, number of piglets in litter subsequent to crossfostering and litter genotype as class effects. The age at farrowing was included into the model in the same way as in case of previous traits. Random part of the model was the same for all analysed traits and represented as effect of common environment in litter where sows had been born, permanent effect of environment in sows’ litters and direct additive genetic effect. Heritability of NBA varied between 0.050 (DS2) and 0.076 (DS3), NSB between 0.004 (DS3) and 0.027 (DS2), NTB between 0.065 (DS2) and 0.073 (DS3) and of NW between 0.010 (DS2) and 0.028 (DS1). Share of permanent environment of sow in phenotypic variance was higher than share of litter effect and mostly lower than share of direct genetic effect.

AB  - The aim of this study was to determine the effect of the sire breed, sire within sire breed, genotype of fatteners, gender of fatteners, gender within sire breed, season of birth of fatteners and mass of warm carcass side on the following traits: back fat thickness - middle of the back (DSL), back fat thickness - lower back (DSK), meat yield of carcass sides (JUSKG) and percentage/share of meat in carcass sides (JUSPRO). The research was conducted in the experimental slaughterhouse and laboratory of the Institute for Animal Husbandry, Belgrade-Zemun, and included females and castrated male animals. Sires of fatteners were pure breeds: Swedish Landrace (SL, n = 10), Large White (LW, n = 3) and Pietrain (P, n = 3), while the offspring belonged to the following genotypes: pure breed - Swedish Landrace (SL, n=252), and crosses of Large White x Swedish Landrace (LW x SL) (n=170), Pietrain x Swedish Landrace (P x SL) (n=13), [Pietrain x (Large White x Swedish Landrace)] P x (LW x SL) (n=35), [Swedish Landrace x (Large White x Swedish Landrace)] SL x (LW x SL) (n=33) and [Large White x (Large White x Swedish Landrace)] LW x (LW x SL) (n=33). The study included total 536 offspring of which 276 are male castrated and 260 female animals. In the winter 24 piglets were born, in the spring 95, in the summer 148 and autumn 269 piglets. It was established that the sire within sire breed Pietrain (S:P) does not affect the variation of the studied traits of fattening pigs (P>0.05); sire within sire breed Swedish Landrace (S:SL) does not affect the varying of the trait JUSPRO (P>0.05); season of birth within the Model 1 does not affect the traits yield and share of meat (P>0.05); the offspring gender within genotype (Gender : Genotype) does not affect the variation of fat thickness at the centre of the back (P>0.05). All other factors (sire breed, sire within the sire breed - Large White, gender and genotype of fattening pigs, gender within sire breed, the mass of warm carcass side, and also birth season of fattening pigs in the Model 2) included in the models showed statistically significant impact on the variability of traits of fattening pigs (P lt 0.05; P lt 0.01 and P lt 0.001).

AB  - The main objective of this study was to score variability of fertility traits of boars as influenced by breed, age at first ejaculation/collection (AFE), the lean meat content (LM), lifetime average daily gain (ADG) and age of boars. The following fertility traits were analysed: libido, duration of ejaculation (DE), ejaculate volume (VOL), the density of the ejaculate (DEN) and sperm motility (MO) of boars. Boars' libido was assessed on the basis of duration of preparing to collection (DPC). The study included 7987 ejaculates from 105 boars of three breeds: Swedish Landrace (SL; n=34), Large White (LW; n=39) and Duroc (n=32). Impact assessment was carried out using the GLM procedure of the statistical package SAS 9.1.3 (SAS Inst. Inc., 2002-2003). Of all the traits analysed, only the DPC and VOL varied under the influence of all investigated impacts. Boars of SL and LW breeds demonstrated superiority in the trait VOL (+12.53 and +11.25 ml) compared to Duroc. Ejaculates of boars with AFE from 23 to 27 weeks had the highest VOL, but with the lowest qualitative properties. Contrary to the negative trend in the manifestation of libido, increase of LM and ADG indicated the trend of increasing DE and VOL. Boars with LM of 61% and higher had the highest VOL, and the differences in relation to the first and second class were +6.32 ml (P lt 0.01) and +5.18 ml (P lt 0.05), respectively. The ejaculate volume of the boars with the highest ADG compared to the other classes was higher (P lt 0.001) by 10.88 and 9.81 ml. Boars in different ADG classes produced ejaculate with differing qualitative property DEN. Correlations between production traits and fertility traits were negligible, and unlike the ADG, only the correlation between LM and DPC was statistically significant (P lt 0.001).

Impact assessment was carried out using the GLM procedure of the statistical package SAS 9.1.3 (SAS Inst. Inc., 2002-2003). Of all the traits analysed, only the DPC and VOL varied under the influence of all investigated impacts. Boars of SL and LW breeds demonstrated superiority in the trait VOL (+12.53 and +11.25 ml) compared to Duroc. Ejaculates of boars with AFE from 23 to 27 weeks had the highest VOL, but with the lowest qualitative properties. Contrary to the negative trend in the manifestation of libido, increase of LM and ADG indicated the trend of increasing DE and VOL. Boars with LM of 61% and higher had the highest VOL, and the differences in relation to the first and second class were +6.32 ml (P lt 0.01) and +5.18 ml (P lt 0.05), respectively. The ejaculate volume of the boars with the highest ADG compared to the other classes was higher (P lt 0.001) by 10.88 and 9.81 ml. Boars in different ADG classes produced ejaculate with differing qualitative property DEN. Correlations between production traits and fertility traits were negligible, and unlike the ADG, only the correlation between LM and DPC was statistically significant (P lt 0.001).",
