Abstract
Relevance. Interbreeding or hybridization is an important factor in increasing pig productivity. As a result of the heterosis effect, the multiplicity of sows increases, the safety of offspring increases, the growth rate of young animals improves, the quality of meat improves and, as a result, the profitability of the pig industry increases.
Methods. The paper evaluates the influence of boar producers from the companies PIC, Genesus Genetics and Hypor on the reproductive qualities of sows of a large white breed from the company Hypor. To implement the experiment, according to the principle of pairs of analogues, 3 groups of sows of a large white breed from the company Hypor were formed, 5 heads each. The sows of group 1 were inseminated with the seed of Landrace boars from PIC, group 2 with the seed of Landrace boars from Genesus Genetics, group 3 with the seed of Landrace boars from Hypor.
Results. In scientific and economic experience, it was found that the multiplicity of sows of the 3rd group amounted to 13.0 heads, which is 7.7% less than in the 1st and 2nd experimental groups. The number of piglets at the time of weaning in groups 1 and 2 per sow was 12, which is 5.3% more than in group 3. For 1 kg of live weight gain, 9.38 EQ was spent on farrowing in the 3rd group, which is 8.1% more than in the 1st and 8.4% more than in the 2nd experimental group. Based on 1000 rubles of feed consumed, in addition, compared with the 3rd group (5.44 rubles), more live weight gain was obtained in the 1st experimental (by 0.44 rubles) and in the 2nd experimental (by 0.47 rubles) groups.
