Abstract

Effect of lactic acid bacteria (Lactobacillus rhamnoses,
Lactobacillus paracasei
and Lactobacillus acidophilus) as food additives
on some parameters of
Bombyx mori L. was carried out . Experimental
product of Lactic acid bacteria was dissolved in distilled water to prepare
one concentration (5mg/ml.) from bacteria in addition to yoghurt and
milk. The obtained results showed that,
Lactobacillus acidophilus
occupied the first category for improving the most studied parameters of
B. mori when comparing to control. Where the 5th instar larval weights
were 2.159g compared to 2.002 g in control , effective rate of rearing
recorded 82.00% compared to 78.00% in control and total haemolymph
protein recorded 64.00mg/ml. compared to 60.99mg/ml. in control.
Cocoon indices registered 1.101 g, 0.209 g and 18.98% for cocoon
weight, cocoon shell weight and cocoon shell ratio comparing to 1.005 g,
0.177 g and 17.61% for the control respectively.
