Evaluation of reproductive performance in sows of Prestice Black-Pied pig - Czech genetic resource

Popis výsledku v původním jazyce

The aim of the study was to evaluate reproductive performance in selected sows of Prestice Black-Pied pig included in Czech genetic resources and also to analyse losses of piglets and culling of sows according to parity order. The experimental work was conducted in a nucleic herd of sows registered in breeding book. A total of 88 sows were included in the observation. Findings indicate that productive parameters of Prestice Black-Pied sows are comparable to productive parameters of modern genotype sows. The results also showed that the highes conception rate after the first insemination was achieved after the second, the third and the fourth parity. Analysis of gestation length revealed that it was significantly influenced by the parity. Very highly significant difference (P&lt;0.001) was found between the 1st and the 2nd parity and between the 1st and the 4th parity. Total numbers of piglets and numbers live-born, stillborn and reared piglets per litter increased significantly (P&lt;0.001, P&lt;0.01, P&lt;0.05) up to the 4th parity, afterwards they continuously decreased. The number of stillborn piglets was the lowest at the 2nd parity, the highest at the 5th and the 6th parity (P&lt;0.05). Length of interval was highly significantly different (P&lt;0.01) between the 2nd and the 5th parity and significantly different (P&lt;0.05) between the 4th and the 5th parity. Differences in the losses of piglets were not significant among parities. The most radical culling of sows was recorded after the 3rd and the 4th parity.
