Impact of hyper-prolific population generation on the reproduction of sows in multiplication herds

Popis výsledku v původním jazyce

The aim of this study was to evaluate the impact of higher selection pressure used in hyper-prolific population on the reproduction of subsequent generations breed in a multiplication herd. Information on 539 liters of 178 ancestors of purebred sows fromboth hyper-prolific and normal population was included. Higher selection pressure particularly on litter size and teat number was applied in the hyper-prolific population. Differences between total number of piglets born, number of piglets born alive ornumber of piglets weaned were neither observed on the 1st only nor on the 1st ? 5th litters. Likewise, no effect on the age of sows at the first parturition and number of insemination per pregnant had been found. A significant response on selection wasdetermined only for teat number. The descendents of hyper-prolific population had about 0.37 teats more than sows of normal population. The results suggest that to achieve desired litter size in multiplication herds the selection criteria
