Abstract
The present investigation assessed the
influence of tryptophan-fortified mulberry leaves on the economic traits of
bivoltine silkworm hybrids. Mulberry leaves were supplemented with tryptophan
at concentrations of 250, 500, and 1000 ppm, and their influence on larval
weight, cocoon weight, shell weight, shell ratio, filament length, and filament
weight was carefully assessed. Supplementation significantly improved all
traits compared to the control. The best results for larval weight (4.453 g),
cocoon weight (2.34 g), shell weight (0.5336 g), filament length (1298.9 m),
and filament weight (0.499 g) were achieved at 1000 ppm, while the highest
shell ratio (24.33%) occurred at 500 ppm. These improvements are likely due to
enhanced nutrient assimilation, efficient metabolism, and increased silk
protein biosynthesis supported by tryptophan. Overall, the findings suggest
that fortifying mulberry leaves with tryptophan, particularly at 1000 ppm, can
serve as an effective approach to improve growth performance and silk
productivity in bivoltine silkworm hybrids.
