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  - The objective of this paper was to study variability, heritability and correlation of the three production traits in 1409 first-calf heifers of Holstein-Friesian breed; including the determination of the quantity of milk during lactation (ML), the quantity of milk fat during lactation (MM) and the quantity of protein during lactation (PR). According to the obtained results it could be concluded that there were statistically significant differences (P<0.01, P<0.05, P<0.001) between ML, MM and PR regarding the effect of season of the first calving and the length of the first lactation. In addition, there were also significant differences (P<0.01, P<0.001) between ML and PR with respect to the effect of farm on which animals were raised, while on MM variability the year and age at first calving had a significant effect (P<0.05). A share of Holstein genes and the ration which animals were fed had no effect (P>0.05) on variability of
any of the examined traits, while the farm on which animals were raised had no effect (P>0.05) on MM, and year and age at first calving did not demonstrate (P>0.05) statistically significant effect on ML and PR. By applying the animal model, based on the use of kinship matrix which involved 3867 animals, by help of REML methodology following heritability coefficients were evaluated: ML h2 = 0.25; MM h2 = 0.40; PR h2 = 0.37. Coefficients determined for genetic and phenotypic correlations indicated existence of complete and positive correlations between these traits the interval of values being from rg = 0.96 between ML and MM to rg = 1.00 between ML and PR.

Research and bulls genetic evaluation for functional longevity were performed on a set of data provided by Agricultural Corporation Belgrade AD (PKB) which contained data on longevity and origin of 22109 cows out of which 26% records were right-censored. Functional length of productive life (FPLP) represents a time period from the first calving to culling or censoring corrected for milk production. Breeding values were estimated using Weibull method of proportional risks within survival analysis a genetic trend for FLPL was calculated using of a regression analysis. The cows included in the analysis were on average first calved in the age of 809 days and had an average share of 81.9% genes of Holstein Friesian breed. An average length of productive life was 1267 days (41.6 months). Distribution of bull standardised breeding values did not statistically significantly differ from normal distribution. An average standardised breeding value was 99. A slightly positive genetic trend was determined, that is, the length of functional productive life was by selection increased by 0.021 day at an annual level while a reliability of estimated breeding values showed a negative trend.

AB  - The conducted research was aimed at constructing equations of selection index that would be used in the selection of the Holstein-Friesian breed animals in Serbia. The construction of the selection index includes the most important milk traits observed in standard lactation: milk yield (MY305), milk fat content (% MF305) and protein content (% MP305). The variance and covariance necessary for the construction of selection index are calculated using the mixed model by the method of least squares. The economic value of traits is expressed as a ratio of relative changes in costs per unit of traits included in the selection index. Livestock included in the research produced, in the first standard lactation, an average of 7681 kg of milk with 3.58% milk fat and 3.28% protein. The equation of the selection index presented in the paper is selected from the group of equations of selection index, as an equation with the highest correlation between the equation and the aggregate genotype, which amounted to 0.2156.

abstract = "The conducted research was aimed at constructing equations of selection index that would be used in the selection of the Holstein-Friesian breed animals in Serbia. The construction of the selection index includes the most important milk traits observed in standard lactation: milk yield (MY305), milk fat content (% MF305) and protein content (% MP305). The variance and covariance necessary for the construction of selection index are calculated using the mixed model by the method of least squares. The economic value of traits is expressed as a ratio of relative changes in costs per unit of traits included in the selection index. Livestock included in the research produced, in the first standard lactation, an average of 7681 kg of milk with 3.58% milk fat and 3.28% protein. The equation of the selection index presented in the paper is selected from the group of equations of selection index, as an equation with the highest correlation between the equation and the aggregate genotype, which amounted to 0.2156., Sprovedeno istraživanje imalo je za cilj konstruisanje jednačine selekcijskog indeksa koja bi se koristila u odabiru grla holštajn-frizijske rase u Srbiji. U konstrukciju selekcijskog indeksa uključene su najvažnije osobine mlečnosti posmatrane u standardnoj laktaciji: prinos mleka (PM305), sadržaj mlečne masti (%MM305) i sadržaj proteina (%MP305).

AB  - This research paper gives an analysis on the size of world's domestic buffalo populations, their milk production and the size of buffalo population in Serbia. Population of domestic buffalo in the world is constantly increasing so that in 2013 there were 199 783 549 individuals, out of which in India in the same year they raised 57.77% of buffalo world population, in Pakistan 18.87%, and in China 11.64%. The share of total world production of buffalo milk in total world milk production in 2012 was 12.92 % or 97 417 135 t out of which 67.76% was produced in India. In Serbia buffalo is raised in the regions of Raška (about 1000 individuals) and Kosovo. Populations of buffalo in central Serbia show a tendency of decreasing in size what was the reason to start a programme of in situ conservation 10 years ago. On the sample of buffalo population encompassed by the programme of conservation the body measures were analysed indicating that the population of buffalo is quite unequalised and that average values obtained for exterior measures are similar to the results obtained by the authors of earlier period for the population of buffalo in the area of former Yugoslavia.
AB  - U radu je analizirano brojno stanje domaćih bivola u svetu, proizvodnja mleka bivola, kao i stanje populacije bivola u Srbiji. Populacija domaćih bivola u svetu stalno raste i 2013. godine bilo je 199.783.549 grla, a od tog broja u Indiji je u 2013. godini gajeno 57,77% svetske populacije bivola, u Pakistanu 18,87%, a u Kini 11,64%. Učešće ukupne svetske proizvodnje bivoljeg mleka u ukupnoj svetskoj proizvodnji mleka 2012. godine bilo je 12,92 % ili 97.417.135 t, a od toga je 67,76% proizvedeno u Indiji. U Srbiji bivoli se gaje u području Raške oblasti (oko 1000 bivola) i na području Kosova. Populacija bivola u centralnoj Srbiji ima tendenciju smanjenja veličine, zbog čega je pre 10 godina počeo da se sprovodi program konzervacije. Na uzorku populacije (37 bivolica) obuhvaćene programom in situ konzervacije utvrđene su prosečne vrednosti za telesne mere. Visina grebena bivolica u populaciji koja je merena bila je 125,97 cm, visina krsta 126,98cm, dužina trupa 142,19cm, dubina grudi 68,75 cm, širina grudi 44,48cm, a obim grudi 184,25 cm. Populacija bivolica je bila dosta neujednačena što ukazuje na odsustvo odgajivačko-selekcijskog rada kod bivola u Srbiji u prethodnim decenijama.

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 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.

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.",

AB  - The aim of this study was to determine the heritability coefficients and the correlation between the number of live born piglets (NBA), the number of stillborn piglets (NSB), the number of total born piglets (NTB) and the number of weaned piglets (NW) in the part of population in Swedish Landrace sows in R. Serbia. The results obtained should enable the selection of litter size traits that would be proposed to be included in the selection - breeding program for this breed. The analysis of parameters was carried out on the basis of data on fertility of 4.061 Swedish Landrace sows and their 15.209 litters realized on two pig farms in R. Serbia. There was a genetic relationship between animals among the farms. Components of variance and covariance of observed traits, the share of additive genetic variance component in the phenotypic and correlation of traits at phenotypic and genetic levels, were evaluated using the method of Restricted Maximum Likelihood (REML) using the Multitrait Model (MM). Heritability estimates for the NBA, NSB, NTB and NW amounted to 6.4, 1.6, 6.7 and 1.1%, respectively. Correlation between the NBA and NTB at the phenotypic and genetic level was complete (rP = 0986, rG = 0938). Correlation between the NBA and NW at the phenotypic level has not been established, while at the genetic level it was weak. We believe that this is the result of the procedure of equalizing of litters after farrowing. In order to obtain objective genetic parameters for NW this procedure should not be applied in pure breed sows.

AB  - Low heritability of pig litter size traits at birth (number of live born piglets - LBP and total born piglets - TBP) and weaning (number of reared piglets - RP) is one of the major problems in their genetic improvement. The effect of selection is directly proportional to trait heritability and inversely proportional to the duration of generation interval. Objective of this study was to establish presence of difference in regard to heritability coefficient values of observed traits, as well as their accuracy depending on the size of data used in the analysis. Heritability coefficients in this study were calculated based on fertility results obtained for Swedish Landrace sows on three pig farms (farms 1, 2 and 3) in the Republic of Serbia. Observed traits - LBP, TBP and RP on farms 1, 2 and 3 were analyzed in the first (2422, 1677 and 2015 litters), in the first two (4190, 2897 and 3377 litters), in the first three (5576, 3809 and 4425 litters) and all available parities (9538, 6340 and 7750 litters) by applying the adequate mixed model of the Least square method. Heritability of LBP calculated based on fertility realized in the first partus ranged from 5.6 to 16.4 %, TBP ranged from 7.0 to 16.8 % and RP ranged from 3.4 to 7.7 %. Introduction into the analysis of the results pertaining to the second, third and subsequent parities lead mainly to detection of lower values of heritability coefficients for observed traits.

AB  - Objective of this paper was to evaluate phenotypic variability of carcass side traits and quality of meat of fatteners (male castrated heads) of Moravka breed (M) and Mangalitsa (swallow-belly Mangalitsa - LM). The quantity and content of meat were determined based on dissection of left carcass sides (Walstra and Merkus, 1996). Also, nutritive properties of musculus longissimus dorsi (m.l.d.) were established. Obtained data were processed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Results of the study show that Moravka fatteners had longer carcass sides (+6.82 and + 5.00 cm) compared to Mangalitsa breed, corrected to average body weight at slaughtering. Fatteners of M breed had in average higher total mass of back-loin part (+0.685, P (lt) 0.05) and average quantity of muscles in the same part of carcass side (+0.631 kg, P (lt) 0.01), compared to fatteners of LM breed. Also, they had higher quantity of muscle in belly-rib part (+0.237 kg, P (lt) 0.05) compared to LM. Share of muscle tissue in back-loin and belly-rib carcass side parts corrected for WCC, was higher in M carcass sides than in LM (P (lt) 0.01). Conversely, muscle tissue content in shoulders of Mangalitsa was higher (+4.8% ; P (lt) 0.05) than in Moravka. Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides. In m.l.d. of Moravka water content was higher (+6.1%, P (lt) 0.01), content of total lipids (-6.5%, P (lt) 0.05) and cholesterol (-19.68 mg/100 g, P (lt) 0.001) was lower than in Mangalitsa.

Tovljenici rase M imali su prosečno veću ukupnu masu leđno-slabinskog dela (P (lt) 0,05) i prosečnu količinu mišića u istom delu polutki (P (lt) 0,01), nego rase LM. Takodje, oni su imali i veću količinu mišića u trbušno-rebarnom delu (P (lt) 0,05) nego LM. Udeo mišićnog tkiva u leđno-slabinskom i trbušno-rebarnom delu korigovan na WCC, bio je veći polutkama M nego kod LM (P (lt) 0,01). Obrnuto, sadržaj mišićnog tkiva u plećkama mangulice bio je veći nego kod moravke (P (lt) 0,05). Udeo mišićnog tkiva u polutkama svinja M, bio je za 4,3% veći nego u polutkama LM. U m.l.d. moravke bio je veći sadržaj vode (P (lt) 0,01), manji sadržaj ukupnih masti (-6,5%, P (lt) 0,05) i holesterola (-19,68 mg/100g, P (lt) 0,001) nego kod mangulice.

abstract = "Objective of this paper was to evaluate phenotypic variability of carcass side traits and quality of meat of fatteners (male castrated heads) of Moravka breed (M) and Mangalitsa (swallow-belly Mangalitsa - LM). The quantity and content of meat were determined based on dissection of left carcass sides (Walstra and Merkus, 1996). Also, nutritive properties of musculus longissimus dorsi (m.l.d.) were established. Obtained data were processed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Results of the study show that Moravka fatteners had longer carcass sides (+6.82 and + 5.00 cm) compared to Mangalitsa breed, corrected to average body weight at slaughtering. Fatteners of M breed had in average higher total mass of back-loin part (+0.685, P (lt) 0.05) and average quantity of muscles in the same part of carcass side (+0.631 kg, P (lt) 0.01), compared to fatteners of LM breed. Also, they had higher quantity of muscle in belly-rib part (+0.237 kg, P (lt) 0.05) compared to LM. Share of muscle tissue in back-loin and belly-rib carcass side parts corrected for WCC, was higher in M carcass sides than in LM (P (lt) 0.01). Conversely, muscle tissue content in shoulders of Mangalitsa was higher (+4.8% ; P (lt) 0.05) than in Moravka. Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides. In m.l.d. of Moravka water content was higher (+6.1%, P (lt) 0.01), content of total lipids (-6.5%, P (lt) 0.05) and cholesterol (-19.68 mg/100 g, P (lt) 0.001) was lower than in Mangalitsa., Rezultati ispitivanja pokazuju da su tovljenici rase moravka imali duže polutke od rase mangulica, korigovane na prosečnu telesnu masu pri klanju.
