ABSTRACT
An experiment was conducted to assess the performance of different mulberry genotypes viz., ME -86, ME-84, ME-18, V1, S36, M5 and DD -1 on the economic parameters namely cocoon weight (g), shell weight (g), pupal weight (g), shell ratio (%) and silk productivity (cg/day). The silkworm hybrid PM ×CSR2 was used in experiment, mulberry genotypes were supplemented with standardized feed additive (horse am + grain amaranthus 50:50). The results registered maximum cocoon weight (g), Shell weight (g), pupal weight (g), shell ratio (%) and silk productivity (cg/day) as compared to un supplemented genotypes.
Key words :
Bombyx mori, Feed additive, Pest incidence, Mulberry genotypes.
