Nutrition plays a pivotal role in sericulture by improving the commercial characters of silkworm. Silkworm being monophagous insects derives almost all the nutrients for its growth from the mulberry leaf itself (Nasreen et al., 1999). Probiotics has higher requirements for scientific substantiation of putative benefits conferred by the microorganisms. Disease free layings (DFLs) of PM x CSR2 multivoltine race was purchased from Government Sericulture Farm, All the rearing operations were carried out according to Krishnaswami et al. (1978). The hatched larvae were divided into untreated and experimental groups with three replications of 25 larvae each and fed with same quantity and quality of mulberry leaves. The different concentrations econorm was prepared and leaves were fed at one of the feeding schedules from the first day of third instar larvae onwards. The initial and final weight of the larvae were recorded to determine the larval growth, Food Consumption (FC), Assimilation, Tissue growth, Efficiency of Converting leaf Ingested (ECI) and Efficiency of Converting leaf Digested (ECD), Approximate Digestibility (AD), Relative Consumption Rate (RCR), and Relative Growth Rate (RGR) were calculated as suggested by Waldbauer (1968). The silkworm larvae treated with 3% econorm the ECD and ECI was 23.32±0.01, 17.77±0.02% during the third, 21.52±0.01, 18.39±0.01% during the fourth and 20.69±0.01, 17.74±0.01%, during the fifth instars respectively. Significantly higher length (46.51 percent) was recorded in the fifth instar larvae fed with 5% econorm concentration. The present investigation clearly resulted that fortification of mulberry leaves with econorm increased the larval growth.
