The results of tests of a new combined feed additive Bioprotektin-KD based on milk thistle extract with the addition of a complex of bacteria of the genus Lactobacillus and Bifidobacterium to restore intestinal microbiota of animals are presented. Preclinical studies on the effectiveness of the feed additive were conducted on mice with experimental antibiotic-associated dysbacteriosis. Studies on the intestinal microbiota of mice revealed varying degrees of effect of different doses of feed additive on the recovery of resident microflora. The results of pre-clinical studies have proven the harmlessness, non-toxicity and efficacy of the feed additive. Clinical trials of the additive were carried out on productive animals. Its effect on the productivity of black-motley breed cows in a livestock farm in the Belgorod region was studied. The use of the functional feed additive Bioprotectin-KD had a positive effect on the milk productivity of black-motley breed cows. Cows in the experimental groups that received the feed additive had increased their milk yield per lactation by 209.41-499.01 kg compared to the control animals, which was 4.01-8.78%. The quality indicators of milk have increased. The composition of the microflora of the experimental (feed supplement recipients) and control calves was studied. It was found that the quantitative composition of probiotic flora in the intestines of young calves of the control group remained practically unchanged throughout the experiment. The number of indigeneous microflora (lactobacilli and bifidobacteria) increased in the experimental animals. The content of lactic acid microorganisms in the experimental calves began to increase on day 6 of feed supplementation and reached physiological norm on day 30. The safety index of the product has been calculated. The use of the functional feed additive Bioprotektin-KD in conditions of a livestock complex has improved such production indicators as calf survival, average daily weight gain, and milk productivity of cows in the experimental groups of animals as compared to the control ones.

Poultry farming is one of the major branches of animal husbandry, which develops through concentration, specialization and intensification on the basis of poultry plants and poultry farms. The increase in production of eggs and poultry meat is based on a significant increase in the productivity of poultry with a simultaneous increase in its population with a high payment of feed by production and the increase in labour productivity. The purpose of the work was to study the influence of enzyme feed additives in the diets of laying hens on the quality of eggs. The researches have been carried out in PJSC “Poultry plant Chelyabinskaya”, which produces high-quality chicken eggs obtained from the poultry cross “Loman LSL-classic”. The object of study was enzyme drugs produced by Sunzyme – a multi-enzyme drug that includes xylanase, cellulase and mannase activities. The dosage of enzyme drugs in the feed mixture of laying hens was: Sunfyze 5000 – 80 g/t, Sunzyme – 100 g/t. The results of researches show that in the groups that received enzyme drugs in their diet, egg production was higher than in the control group. So, for the entire period of researches the hens of the experimental groups were significantly superior to the control group in terms of egg production per average laying hen. The largest difference was in hens of the 1st experimental group (enzyme drug Sunfyze) – 10,8 eggs; the smallest in hens of the 3rd group (enzyme drugs Sunfyze and Sunzyme) – 5,7 eggs. In hens of the 2nd experimental group compared with hens of the control group egg production was higher by 7,9 eggs. The best indicators of production efficiency have been obtained in the 1st experimental group of laying hens, which were fed with the enzyme feed additive Sunfyze to reduce the nutritional value of the diet according to the matrix.
