EFFICIENCY OF THE USE OF PROBIOTICS IN BROILER FEEDING
Abstract
The article, on the basis of conducted scientific research, considers an important problematic issue regarding the use of probiotic preparations in poultry feeding. Moreover, today the special demand in the world for poultry products is constantly growing, and this is explained by its complete composition, rich in easily digestible proteins, lipids and polyunsaturated fatty acids. In addition, the amount of protein in poultry meat is approximately the same as in pork and lamb, but the content of essential amino acids is higher than in the meat of other animals. To date, numerous scientific studies prove the effectiveness of the use of probiotics in feeding broilers. We found that the introduction of probiotics into the diets of broiler chickens had a positive effect on growth intensity, digestion and metabolic processes in the body, productivity, livestock preservation, and feed conversion. However, not all additives presented on the domestic market satisfy the requests of producers of poultry products. Therefore, the purpose of our research was to study the effectiveness of using a probiotic feed supplement in different periods of growing broiler chickens. Research has established that during the entire period (42 days) of rearing, the live weight of chickens in the experimental groups exceeded the control indicator by 5.9–13.0%, the survival rate of the stock ranged from 95–100%. The use of compound feed enriched with a probiotic feed additive in feeding broiler chickens of the experimental groups contributed to better assimilation of the main nutrients of the feed. It was proved that the broilers of the research groups digested crude protein, crude fat and crude fiber of feed better, which indicates the effective effect of probiotics in general metabolism. The results of the conducted scientific studies showed that the economic efficiency of using 3% of the probiotic feed additive "Trilacto-Kor" from the 1st to the 14th day of raising chickens was 16.1%, from the 1st to the 28th day – 22,4%, with the use of the supplement during the entire period of growing broilers – 27.4%, and with periodic introduction into the main diet for 7 days in the stratum, growth and finishing periods – 30.5%. Thus, probiotic preparations in the form of feed additives are increasingly used in broiler breeding for both therapeutic and prophylactic purposes. The market of drugs of this group is actively developing and is filled every time with new samples of domestic and foreign production.
