dc.description.abstract | The main objective of this study was to investigate the importance of the sires effect on fenotypic variability of production traits of performance tested boars of Large White, Landrace. and Hampshire breeds of pig. The data used in this study were collected from 738 performance tested young boars at the PKB Pig Testing Station in Padinska Skela, from 1995 to 2001. Analysed traits were initial age (IA), final age (FA), test duration (TD), average daily gain on test (ADG), lifetime ADG (LADG), amount of total consumed feed (TF), feed conversion ratio (FCR), daily feed intake (DPI) and body composition traits taken by ultrasonic equipment PIGLOG 105 (backfat thickness - BF1 and BF2, muscle depth - MD and lean meat content - LM) Data was analysed by fixed models of least squares method. Analysis of variance showed that sires nested within Hampshire breed highly significant influenced all investigated traits. Growth, feed efficiency and body composition traits except muscle depth, were highly significant influenced by sires of Large White breed. All feed efficiency traits and muscle depth were not influenced by sires within Swedish Landrace breed. | en |
dc.description.abstract | Osnovni cilj ovih istraživanja je bio da se utvrde razlike između grupa kombinovanih podataka punih i polusrodnika nerastova-očeva tri različite rase svinja za proizvodne osobine evidentirane u direktnom testu u uslovima centralne testne stanice. Istraživanja su obavljena u Stanici za ispitivanje proizvodnih sposobnosti svinja, PK "Beograd" u Padinskoj Skeli. Ispitivanjem je bilo obuhvaćeno ukupno 738 grla tri rase svinja i to: švedskog landrasa (n = 129), velikog jorkšira (n = 473) i hempšira (n = 136). Testirani nerastovi su bili potomci od 61 oca, tako da je za sve tri rase prosečan broj potomaka testiranih po ocu iznosio 12,1. Broj očeva od kojih su vodila poreklo testirana grla rase švedski landras iznosio je 15, veliki jorkšir 34 i hempšir 12. Ocena i testiranje hipoteze o uticaju efekata nerastova-očeva na variranje proizvodnih osobina izvršena je upotrebom metoda najmanjih kvadrata (Harvey, 1990). Očevi ugnježdeni u okviru rase hempšir su statistički značajno (P lt 0,05, P lt 0,01 i P lt 0,001) uticali na varijabilnost svih ispitivanih proizvodnih osobina sinova. Osobine porasta, iskorišćavanja hrane i kvaliteta trupa, izuzev dubine m.l.d.-a, nerastova rase veliki jorkšir varirale su pod uticajem očeva. Nisu ustanovijena statistički značajna variranja (P>0,05) ni jedne ispitivane osobine iskorišćavanja hrane i dubine m.l.d.-a između grupa polusrodnika nerastova-očeva rase švedski landras. | sr |
