Abstract
Silkworms fed on supplemented leaves dipped in different lower and higher concentrations of three
secondary metabolites to all the larval instars four times in a day. Lower concentrations of pectin, amino
acid mixture and proline proved to be considerably effective showing higher food consumption,
digestibility, reference ratio and growth index. These findings indicated that nutritional indices were
found to be highest in Pectin (0.5 %) and Amino acid mixture (0.01 %) when compared with natural diet,
which was pointed out the superiority over natural diet, which showed that significantly, improved the
silk production and they can recommend as leaf supplementation for increasing the income of silk as
well.
