Productivity of Kavkaz-2 silkworm strain on artificial diet IPS-1 with synthetic amino acid supplementation

Abstract

This study presents data on rearing the Kavkaz-2 silkworm strain (Bombyx mori) using our patented artificial diet (IPS-1) supplemented with synthetic amino acids to enhance biological parameters, silk productivity, and reproductive performance. The research demonstrated that incorporating specific amino acid concentrations into IPS-1 (0.5 % L-glycine, 0.7 % L-alanine, 0.8 % L-serine, 1.1 % L-tyrosine, and 0.3 % L-methionine) resulted in: 1) reduced rearing duration by shortening the fifth instar larval stage by 2 days; 2) increased fifth instar larval viability (99.6 %); 3) improved cocoon weight (4.2 %), average cocoon shell weight (9.2 %), and silk yield (5.0 %); and 4) enhanced reproductive parameters including clutch size (5.5 %), average egg weight (1.4 %), and total clutch weight (5.4 %) compared to traditional mulberry leaf feeding.
