Biologically Active Feeds Based on Local Raw Materials

Abstract

An efficient technology for protein extraction from silk production waste has been developed. The dynamics of the degree of precipitation of alkaline hydrolysates by acetic acid has been studied. The amino acid composition of the isolated protein was determined, which contains 9 essential acids. IRspectroscopy and elemental analysis showed the purity of the isolated protein. Approbation of protein in the composition of feed in fish farming showed high fish productivity and efficiency in terms of feed ratio. The use of Bombyx mori protein for poultry in the amount of 0.5% 1% increases the gain in poultry meat and egg production by 48.25%.
