The influence of the complex of enzymatic probiotics on the metabolic processes of calves in preweaning period

Abstract

The main task for the agro-industrial complex of the country and in the Amur region in particular is the rearing of healthy livestock and obtaining environmentally friendly products from it. In order to achieve these tasks special attention should be paid to the complite balanced feeding of animals starting with the birth of the animal. Under the conditions of the region when harvesting their own feed, there is a shortage of normalized nutrients, which leads to a decrease in the productivity of animals, digestive disorders, which in turn leads to various diseases of the gastrointestinal tract and a decrease in the immune status of animals. In veterinary practice antibiotic therapy is used to treat diseases, which along with pathogenic and conditionally pathogenic destroys useful microflora. Accumulating in the body antibiotics cause harm not only to animals, but also carry a danger to humans. From the use of antibiotic therapy develop dysbacteriosis, which directly affect the development of the animal as a whole. Application of probiotics to calves from the first day of life promotes early formation of a rumen, the best assimilation of nutrients that in turn leads to intensive growth and development of a young organism of an animal. When using probiotics in animals, the intestinal microflora is normalized, thereby reducing the risk of dysbiosis and diarrhea, as well as improving growth, development and metabolic processes. In the farms in the Amur region the use of probiotics in feeding calves of the dairy period has not been studied enough. The studies have been carried out under the conditions of LLC “Priamurie” in the Amur region on calves of Black-and-White breed in the preweaning period. 3 groups animals with 10 heads in each have been formed and selected on the principle of pairsanalogues. Calves from the control group have been fed a main diet adopted in the farm, herdmates of the 1st experimental group probiotic “Promilk” in a dose of 20 g per head/day into the main diet have been pu, and the 2nd experimental the complex of enzymatic probiotics “Promilk” and probiotic “Vitacell” 10 g of each per head/day. It has been found as a result of the experiment that the input of enzymatic probiotics into the diet has increased the live weight of calves in both experimental groups compared to the control one.
