Abstract

Recipes were developed for compound feeds for boars with replacement of 5% and 10% of natural barley grain with sprouted grain. The use of experimental feeds allowed to increase the volume of boar ejaculate-by 25.5% and 31.9%; sperm concentration-by 18.4 and 20.1%; sperm survival-by 7.7 and 9.2 hours; sperm resistance by 27.0 and 27.8%. The fertilization rate of sows increased by 3.0 and 6.3%, multiplicity-by 3.1 and 4.2%, large-scale fertility remained at the control level. The cost of compound feed increases with the Introduction of sprouted grain, but this increase is economically justified, since the productivity of animals increases. The cost of a dose of sperm from boars is reduced by 2.8 and 3.2 rubles, the number of farrowed sows increases in the experimental groups by 51.8 and 71.4%, respectively, and the cost of one Piglet is lower by 12.4 - 17.5 rubles or 8.6 - 12.6%..
