INFLUENCE OF PARENTS ON THE REPRODUCTIVE QUALITIES OF SOWS

Abstract

The research was conducted on the farm Bogdan Khmelnytskyi LLC. 9 sows of the Large White breed were selected for the study . The sows were divided into three groups and a boar was attached to each group. of the appropriate breed. Boars fruit trees imported from various breeding farms. The first group included boars of the Large White breed, the second boars of the Maxter breed, and the third boars of the Kantor breed. In terms of fertility, sows of the second group prevail with an indicator of 12.4 litters, which is 2.1-0.3 heads more. knife from sows of other groups. In terms of nest mass , animals of the second group prevailed over all others with an indicator of 16.4 kg. The advantage was 3.6-0.9 kg compared to other groups. The highest milk yield was shown by sows of the second group with an indicator of 77.62 kg. The advantage over other groups was: from 11.3 to 1.95 kg. Having spent Evaluation of sows of all three groups using the maternal and reproductive quality index , it can be said that according to these indices , animals of the second and third groups show the best results in comparison. with sows of the first group. This makes it possible to state that sows covered with boars of the Maxter and Kantor breeds show better reproductive qualities in comparison with sows covered with boars of the large white breed .
