Abstract
The use of intensive technologies in industrial livestock leads to an increase in the stress sensitivity of animals, a decrease in their immune status and the development of pathological conditions. To increase the safety of young stock, including by reducing its incidence and death from diseases, feed additives are being developed, including probiotics, prebiotics and (or) other components that stimulate the immunological resistance of animals, their growth and productivity. This article examines the effectiveness of the use of a complex feed additive containing a multienzyme enzyme preparation, the probiotic preparation Prolam and amaranth oilcake to increase the efficiency of growing calves. The studies were performed on calves of the red-motley breed from 10 days of age in Voronezhpishcheprodukt LLC. The study of the effect of the feed additive on the immune and clinical status was carried out on 40 calves, which were divided into 4 groups. The calves of the three experimental groups used the feed additive at a dosage of 5, 10 and 15 g per day from day 10, the control drug was not used. The use of a complex feed additive to calves in the neonatal period helps to optimize the process of formation of intestinal microbiocenosis, increase the body's natural resistance and adaptive immune response to antigenic effects, accompanied by a decrease in the incidence of animals, the duration and severity of gastrointestinal pathology. The use of the feed additive in the dosage of 10–15 g / head per day favorably affected the growth rate and the natural resistance of the body of calves. The data obtained are the basis for the inclusion of feed additives in the diet of young farm animals.
