ABSTRACT

The influence of the dietary supplementation of the herbal tonic “Alloe” containing principally the extract of Aloe vera Linne. on the growth and the cocoon characteristics of the mulberry silkworm Bombyx mori L. commercial cross breed race L x CSR2 during its fifth instar was experimented. This, in general, elicited better response of the growth and the cocoon characteristics of this silkworm. Specifically, the Aloe vera tonic at 2.0 per cent concentration resulted higher larval growth and increased the weight of cocoon. The mean larval weight, relative growth rate, effective rearing rate, larval consumption index of the final instar larvae of B. mori increased with this supplementation of Aloe vera tonic. The average pupal weight and mother moth weight also increased as a result of this supplementation. Maximum shell weight and shell ratio were noted in the experimental sets treated with the A. vera tonic. In addition, the fibroin content of the cocoon shell produced by this silkworm in response to the dietary supplementation of Aloe vera tonic treatment also showed significant increase over the control The overall performance of Bombyx mori in response to this A. vera tonic treatment observed in the present study and the evaluation index values worked out showed that the growth and the cocoon parameters could be improved with the supplementation of A. vera commercial preparations.
