IMPROVING THE REPRODUCTIVE ABILITIES OF SOWS IN CONDITION OF INDUSTRIAL COMPLEX WHEN USINGIN THE DIETPROBIOTIC PROVEN WITH NATURAL AND SORPTION ADDITIVE CORETHRON
The article presents the data of experimental studies conducted on the basis of pig-breeding industrial complex of LLC "SKIK Novomalyklinsky" Ulyanovsk region, on 2 groups of sows (8 heads each). Feeding of sows was carried out by the same complete feed. At the same time, the group II sows were included in the diet, at the rate of one head per day, a complex of feed additives - adsorption mineral "Coretron" 30 g in combination with probiotic "Provagen" at a dose of 200...220 g per 1 ton of feed. Inclusion in the diet of sows of the probiotic "Provagen" in combination with a sorption additive "Koratron" is stated to be effectively, because in addition to substantial improvement of microbiocenosis of the diet in this group and largepiglets fertility, not only their growth intensity but their safetywere recorded, which allowed them to have for weaning in the nest of 13.13 piglets that by 34,7 % more than quantity of piglets survived to weaning from sows in the control groups (9,75 goals).
