Abstract
The silkworm larvae were fed on probiotics
fortified mulberry leaves treated with five different kinds of Vital dye as
feed supplements and given for silkworm hybrid, CSR-2 Double Hybrid from fourth
instar onwards till last day of feeding. The same was carried out with chow
feed coloured with vital dyes. Among the probiotics tested, was found to be
superior for all the physical and growth parameters such as larval length and
weight at total larval duration. The mulberry fortified with probiotics and
chow feed fortified are showing remarkable results during their life cycle at
larval and cocoon stages. The interaction of feed additives probiotics along
with their vital dye supplementation indicated that these combinations bring a
superior traits during all larval parameters studied larvae length varies
between 2.13-4.02 cms in V instar and 4.15-6.90 cms in V instar larva.
Similarly nutritional indices like ingesta varies between 33.41-94.99 in IV and
V instar and for digesta 29.01-43.75. Approximate digestability and reference
ratio lies between 79.15-84.65; 6.49-7.60 for IV and V instar larva. Highest
Efficiency conversion indices (ECI) for larva was 3.05-5.23, for Cocoon it is
2.69 and for shell it is 0.49 Efficiency digestion indices ECD recorded was
3.23-4.83 in larval stages, in Cocoon it was 4.55 and in shell it was 0.83.
