 ABSTRACT

The study was conducted to determine the effect of 1% N with different doses (0.025, 0.05, 0.075, 0.1, 0.125 and.0.150%) of ascorbic acid on growth and silk production of larvae. Larvae were fed on mulberry leaves treated with 1% N and ascorbic acid in various combinations. Data was recorded on food consumption, co-efficient of utilization, body weight, body length and cocoon shell ratio and analyzed statistically. It was revealed that T5 (0.2%N +0.05% vitamin C) proved as the best treatment, which yield better results than all other test treatments about all the parameters under study. In conclusion, the higher doses of vitamin C, lowered the silk yield and caused decline in growth of silkworm larvae

Keywords: Samia cynthia ricini, ascorbic acids, feed efficiency, growth rate
