Correction of intestinal microbiocenosis of monogastric

The introduction of a liquid probiotic lactic acid feed additive based on Lactobacilli Lactobacillus plantarum; L. johnsonii, L. paracasei; L. sakei; L. reuteri into the diet of young pigs led to a positive correction of intestinal microbiocenosis. Liquid lactic acid probiotic feed additive from lactobacilli, additionally enriched in vitro with biologically active selenium and iodine, significantly improved the microflora of the digestive tract, and had a beneficial effect on the health, growth and development of animals. The average daily increase in live weight of pigs at the age of six months receiving probiotic lactic acid feed additive with iodine and selenium was 18.1 % higher compared with the control. Experimentally, doses of liquid probiotic lactic acid feed additive containing lactobacilli from 1010 to 1012 CFU / g, with selenium and iodine, have been established for pigs in the diet: up to 90 days of age - 10 ml per 1 head per day; during the fattening period (age from 91 to 180 days) - 20 ml per 1 a head per day. The optimal doses of selenium and iodine in a probiotic supplement, allowing to maintain the content of these trace elements in the diet at 0.20 mg /kg, iodine - 0.35 mg /kg of feed, were: Se - 20 mg/l; I - 35.0 mg/l.
