AB  - The analysis included 433 daughters of 10 bulls, calving for the first time in the period from 2007 to 2014, on 6 dairy farms of the Agricultural Corporation Belgrade AD. Fixed factors included in the model were the effects of the farm, year of calving and calving season, and as a random factor the impact of the bull sire. The observed fertility properties on the basis of which breeding values were calculated were the number of days of gestation, the age at the first insemination, the service period duration and the calving interval. Bulls were ranked on the basis of these properties and using the Spearman correlation coefficient, the degree of agreement between the ranks was determined. According to the breeding values calculated by using the Best Linear Unbiased Prediction (BLUP) method, the sire 1517 was best ranked for the trait duration of service period (-34,94 days) and the calving interval (-36,14 days), relative to the average of daughters. The effects of the farm and year of calving showed no significance (p>0.05) except on the duration of the gestation. The effect of the calving season showed a very high significance (p (lt) 0.001) for the following properties: age at first insemination, duration of the service period and calving interval, as well as significance (p (lt) 0.05) for the property duration of the gestation. A statistically very significant degree of agreement between the service period and the calving interval of 0.99** (p  (lt) 0.01) was determined by the Spearman coefficient of correlation, while there was no significant difference between the other properties (p>0.05).
AB  - U analizu je uključeno 433 prvotelke, kćeri 10 bikova, prvi put oteljene u periodu od 2007. do 2014. godine, na 6 farmi krava Poljoprivredne korporacije Beograd AD. Kao fiksni faktori u modelu, uključeni su: uticaji farme, godina telenja i sezona telenja, i kao slučajan faktor uticaj bika oca. Praćene osobine plodnosti na osnovu kojih su izračunate priplodne vrednosti su: broj dana bremenitosti, uzrast pri prvom osemenjavanju, dužina servis perioda i međutelidbeni interval. Bikovi su rangirani na osnovu pomenutih osobina, a primenom Spirmanovog koeficijenta korelacije utvrđen je stepen slaganja između rangova. Prema izračunatim priplodnim vrednostima metodom najboljih linearnih objektivnih pokazatelja (Best Linear Unbiased Prediction - BLUP) utvrđeno je da je bik otac, broj 1517 je najbolje rangiran za osobine trajanje servis perioda (-34,94 dana) i međutelidbenog intervala (-36,14 dana) u odnosu na prosek kćeri.Uticaji farme i godine telenja nisu pokazali značajnost (p>0,05) samo kod osobine trajanje bremenitosti. Uticaj sezone telenja je pokazao vrlo visoku značajnost (p (lt) 0,001) za osobine: uzrast pri prvom osemenjavanju, dužina servis perioda i međutelidbeni interval, kao i značajnost (p (lt) 0,05) na osobinu trajanje bremenitosti. Spirmanovim koeficijentom korelacije utvrđen je statistički vrlo značajan stepen slaganja između trajanja servis perioda i međutelidbenog intervala (p (lt) 0,01), dok između drugih osobina nije bilo značajnosti (p>0,05).

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.
