dc.description.abstractIn 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).en
dc.description.abstractU ovom istraživanju cilj je bio da se utvrdi kakav uticaj su imali sledeći faktori: godina, farma, i genotip nazimica kao i regresijski uticaj telesne mase na kraju performans testa na sledeće ispitivane osobine: uzrast na kraju testa (UKT), životni dnevni prirast (LDG), debljina slanine merena na dva mesta (u skladu sa Glavnim odgajivačkim pogramom), dubina dugog leđnog mišića (BM) i procenjena mesnatost (M). Istraživanjem su obuhvaćene dve farme svinja (farma 1 i farma 2), kroz tri uzastopne godine (godina 1, godina 2 i godina 3). Broj testiranih grla po godinama iznosio je: 974 (godina 1), 1311 (godina 2) i 757 (godina 3). Testirane nazimice su pripadale sledećim čistim rasama švedski landras, veliki jorkšir i Duroc. 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).sr
