The effectiveness of a night shift when farrowing sows in reproduction farm LLC “Cherkizovo-Svinovodstvo”

Abstract

The reproductive traits of sows are affected by many factors, so in the practice of work of reproduction farm should take into account the influence of each of the its in order to increase the output of piglets from the breeding stock, especially in industrial pig farms. The safe passage of farrowing has the big influence on the prolificacy of sows, since many piglets die directly during farrowing. Therefore, in modern industrial enterprises that use highly productive hybrid sows it is necessary to constantly monitor the passage of farrowing sows. Researches have been carried out in the reproduction farm of the pig breeding complex on the implementation of the night shift in the technological process at the farrowing site and its influence on the indicators of reproductive traits of sows of different age groups. The results of researches have shown that the implementation of the night shift in the reproduction farm of the industrial pig breeding complex using highly productive hybrid sows is necessary and economically has been justified. The prolificacy of sows of the 1st group was 12,9 piglets, and sows of the 2nd group by 0,6 % more. Per litter 1,25 stillborn piglets have been detected in the 1st experimental group of sows, while in the 2nd group there were by 0,25 piglets less. A total of 803 heads have been received in the 1st experimental group stillborn piglets, in the 2nd group 621 heads have been received or bys 182 heads less. When using the night shift in the 2nd group of sows additionally 182 piglets have been obtained. At the same time, the difference between the cost of additionally saved piglets and the cost of organizing the night shift for the two-week research period was 195,7 thousand rubles.
