Realized effect of different selection criteria applied in bredding herds on performance in multiplier herds

Popis výsledku v původním jazyce

Different breeding management as well as higher selection pressure on the performance traits has been applied on population of Large White sows. The sows were divided into two subpopulations (hyperprolific or normal). The hypothesis that progeny of sowsfrom hyperprolific subpopulation breed in multiplier herds have higher litter size traits was tested. The effect on the growth performance traits are reported so. About 1933 farrowings of 614 Czech Large White sows were included. The number of functionalnipples increased remarkably in the sows of hyperprolific subpopulation although the selection pressure on this trait was small. Likewise, both studied growth performance traits reacted positively on the selection pressure and the differences between populations were highly significant. Surprisingly, no significant differences in litter size traits were found either in the first or in the first to fifth parity. The results outlined that the selection criteria applied in the breeding her
