Abstract
Food consumption and utilization of a bivoltine silkworm hybrid was studied to understand the efficiency of food conversion into larval body, cocoon and cocoon shell during the life cycle. The ingesta, digesta, excreta, reference ratio, mean daily food ingested and digested in different larval instars were recorded. All these parameters differed from one larval instar to another. The AD and ECI were inversely correlated with the larval age. The ECI and ECD for body, cocoon and cocoon shell were 23.63, 17.59, 9.496 and 55.12, 46.65 and 25.23% respectively. Ingesta and digesta required to produce a gram body weight, progressively increased from first to fifth instar. Ingesta and digesta for one gram body, cocoon and cocoon shell production were 4.402, 5.762, 10.649 g and 1.840, 2.184 and 4.047 g respectively.
