Development of the probiotic feed supplement based on lactobacillus plantarum to increase the broiler productivity

Abstract

This article reflects the results of the development of a method for testing a promising feed supplement based on the Lactobacillus plantarum strain, with a high antagonistic activity to campylobacter. To determine the digestibility and use of food nutrients by broilers, a physiological (balance experiment) was conducted on three males from each group at the age of 28 days. By the end of the growing period, there was a clear tendency to increase the live weight of 36-day-old chickens compared with the control group in experimental group 2, which received a feed supplement, including bacteria Lactobacillus plantarum. She was 4.0% higher. As a result of scientific work, it was shown that feeding broiler chickens with a probiotic feed additive based on Lactobacillus plantarum helps to increase their productivity during the entire growing cycle.
