Experience of application of a new feed additive in carp feeding

Abstract

The article discusses the results of the application of a new feed additive Atysh (Enterococcus faecium (2?109 CFU) and Lactobacillus acidophilus (1?107 CFU)) in the feeding of carp fingerlings (Cyprinus carpio).  After the introduction of the Atysh in the diet of carp at a dosage of 0.08 g / kg of feed, the growth of fingerlings by 7.54% was established in the fifth week of the experiment. The application of the probiotic did not have a negative effect on the amino acid composition of fish tissues. An increase in the level of macronutrients and a decrease in a number of essential and conditionally essential trace elements were also recorded. A significant decrease in a number of toxic elements in the carp body has been established.
