Abstract

Modern methods of industrial poultry farming involve intensive technologies that do not always correspond to the physiological characteristics of the bird's body. Increasing the preservation of chickens and ensuring high intensity of their growth at all stages of rearing is one of the most urgent problems of modern poultry farming. The low resistance of chickens at an early age is due to their biological characteristics, high concentration of livestock, the negative impact of technological factors and insufficiently balanced feeding, which leads to stress and affects the level of productivity of poultry and, accordingly, increases the percentage of mortality. A study of the effectiveness of the probiotic drug "Biomagn" was conducted in order to normalize the intestinal microflora of broiler chickens and strengthen immune and antioxidant functions. Microbial preparations from associations of nonpathogenic bacteria have a positive effect on the productivity and natural resistance of the body. It was established that the introduction of the probiotic drug "Biomagn" into the diet of broiler chickens in the form of a supplement to the main feed leads to inhibition of the growth of obligate and facultative microflora, compared to the indicators in the birds of the control group (Р≤0.05). The results of microbiological studies of samples of the contents of the small intestine, rectum, and caecum of broiler chickens of the control and experimental groups showed that the use of a prebiotic preparation helps to inhibit the development of conditionally pathogenic microorganisms Campilobacter spp., Salmonella liquid groups, the number of enterobacteria and an increase in the number of Lactobacillus bacteria and Bifidobacterium Thanks to this, they are able to create a bacterial balance during the colonization of the digestive tract and prevent the development of harmful microflora there.
