Combined Silage for Pigs with the Use of Bacillus subtilis Probiotic

In order to increase productivity of pigs, combined silage including Bacillus subtilis probiotic has been developed. The studies showed that when 20 % of the combined silage (75 g of the Bacillus subtilis culture per 1 ton of alfalfa, 50 kg of pumpkin and 60 kg of grape pomace) is introduced into the nutrient rations of boars, their ejaculate volume increases by 20.9 %, the number of sperms - by 22.1 %, preservation of SH groups - by 13.6 %, operation of power supply system in the gametes - 2.6 times, and fertility of sows from the first insemination - by 25.0 %. Introduction of combined silage with Bacillus subtilis into the diet of sows (1 ton of alfalfa + 90 kg of grape pomace + 50 kg of pumpkin + 100 g of the probiotic) increases the number of weaned piglets by 0.6 animals, weight of weaned piglets by 2.3 kg, and increases piglets viability by 5.0 %.
