Abstract

The influence of probiotic preparation “Biological Feed Complex” on the productivity of broiler chickens has been studied. The results of the study showed that the use of the biological feed complex (BFC) improved growth and development of broiler chickens during the entire period of study. Through observations, we have seen that starting with 14 days of age, the live weight in the experimental group started increasing, compared to the reference group, and this trend persisted until the end of the experiment. In the age of 21 days, broiler chickens in the experimental group in terms of live weight were superior to the reference group by 3.3% (p<0.05-0.001). On the 28th day, the experimental group was ahead of the reference by 3.5%, in the age of 35 days - by 5.8% (p<0.05-0.001), and in the age of 42 days - by 11% (p<0.05-0.001). The resulting effect in the dynamics of growth in the experimental group was determined by the positive influence of microorganisms in the composition of the BFC on early and subsequent formation of normal flora of the intestines of broiler chickens. The highest preservation rate of 97.5% in the experimental group suggested that maintaining the microbiocenosis in poultry with probiotics allowed improving the immune status of the organism and withstanding many types of infection. The absolute growth in both groups of chickens during the first week was equal. In terms of absolute growth, broiler chickens in the experimental group were superior to analogues mostly in week five, when the difference was 18.8%, and in week six the difference was 15.7%. The use of BFC probiotic in the diet of chickens from one day of age until slaughtering contributed to increasing digestibility and absorption of feed nutrients. Positive effect has also been established on the biochemical parameters of blood, improving metabolic processes in broiler chickens, and the morphological composition of carcasses. When the probiotic of the BFC feed additive was included into the diet of broilers, it was noted that the product met the main safety requirements of TR CU 021/2011 “About food safety”. The performed studies showed that adding the BFC feed additive into the diet of broiler chickens allowed to reduce the cost of 1 kg of meat in the experimental group by 5.70 rub, and increase profit by 447 rub. and profitability by 10.2%.
