The Impact of Aminoacids on the Silk Productivity of Mulberry Silkworms in the Re-Feeding

In recent two years re-feeding implementations of the mulberry silkworm have been practiced widely in the Republic of Uzbekistan. This article presents the results of the research on analysis of some amino acids at the process of re-feeding breeds and strains in summer time. It was ascertained that amino acids lysine and methionine affected favorably on silk productivity indications. In the control variant where the mulberry leaves were processed with amino acid solution of 0, 5 %, increase in cocoon mass varied from 1, 9 % to 21, 1 % over the control. The effect of amino acid application also occurred in silkworm moth out. Silkworm moth out was in considerable higher rate in all breeds and strains of experimental variants compared to re-feeding of other usual caterpillars.
