PRODUCTIVITY AND MEAT QUALITIES OF PIGS WHEN USING COMPLEX FEED ADDITIVES WITH PROBIOTIC PROPERTIES IN DIETS

The article presents research data obtained by studying the reproductive qualities of sows, as well as the meat productivity of their offspring through the use of a complex feed additive with probiotic properties in feeding diets. The study of the effect of a complex feed additive with probiotic properties on the reproductive functions of sows, their productivity, as well as on the growth, development and meat productivity of the offspring is a very urgent problem and is of great scientific and practical interest, including for the implementation of priorities of National projects in the field of agriculture. In this regard, the aim of the research was to study the reproductive qualities of sows, as well as the meat productivity of their offspring through the use of a complex feed additive with probiotic properties in feeding diets. Scientific and production experience was conducted on Yorkshire pigs in the conditions of JSC named after Lenin of the Beloglinsky district of the Krasnodar Territory. In the first scientific and economic experiment, the effect of a complex feed additive and the probiotic Bacell-MT on the reproductive qualities of sows was studied. To conduct the experiment, 3 groups of sows of the last 30 days of pregnancy, 5 heads each, were formed according to the principle of pairs of analogues. The sows of the first control group consumed the main ration, the second experimental group – the main ration with a complex feed additive at the rate of 100 mg / kg of live weight once a day, for 25 days before farrowing and 25 days after farrowing; the third experimental group - the probiotic supplement Bacell-MT at the rate of 20 g per 10 kg of compound feed; within 25 days before farrowing and 25 days after farrowing; piglets of the first group consumed complete compound feed, the second group – complete compound feed from a complex feed additive at the rate of 100 mg / kg of live weight from the first day of weaning 1 time per day, for 25 days; the third experimental group probiotic supplement "Bacell-MT" at the rate of 20g per 10 kg of compound feed, for 25 days. The use of feed additives in the diet of sows had a positive effect on the normalization of physiological processes in the body and their state of health, reduced feed consumption, increased the safety of piglets and gained additional weight gain.
