Abstract

Feeding is the most important factor in silkworm rearing as it has a direct impact on growth and development of worms. Silkworm requires five hourly feeds a day but the rearers of J&K state feed the worms two times only which results in low cocoon yield. The present study was conducted on authorized commercial silkworm hybrid CSR2 x CSR4, comprising of four treatments viz. single feeding (24 hrs. gap), 2 feedings (12 hrs. gap), 3 feedings (8 hrs. gap) and 4 feedings (6 hrs. gap). Seventeen commercial characters were studied. Data generated was statistically analyzed and also evaluated cumulatively by Manos’ Evaluation Index (E.I.) method.
