INFLUENCE OF DIFFERENT DIETS ON THE ACTION OF LACTIC ACID SUPPLEMENT IN RAISING BROILER CHICKENS

Abstract

The effect of 0.3% lactic acid supplement on the growth and safety of broiler chickens was evaluated depending on the diet pattern used. It has been found that the effectiveness of the action of this probiotic is influenced by the volumes of feeds of animal origin and vegetable oil. It has been revealed that the action of lactic acid supplement against the background of high-protein diet results in decreasing production performance of birds. As compared with the control group of animals not fed with animal feeds, the average live weight of experimental broiler chickens at the end of the experiment was lower by 183.1 g. In the absence of feeds of animal origin and the lesser content of vegetable oil, there was observed the higher average live weight of young birds as compared with the broilers raised on high-protein diets. It is supposed that as a result of balancing a high-protein diet by adding vegetable oil, a share of linolenic acid increases. Considering that probiotics also produce fatty acids in the organism, it can be supposed that the total effect of fatty acids sets conditions for such an environment in the gastrointestinal tract of birds, which inhibits the enzymatic processes.
