Abstract | ||||
Effect of Hibiscus sabdariffa as food additives on rearing performance of silkworm, Bombyx mori L. was studied. Dried flowers of H. sabdariffa were crushed and soaked in distilled water to prepare different concentrations (20, 40, 60, 80 and 100 mg/ml.). The obtained results showed that, the concentration 60 mg/ml. of H. sabdariffa occupied the first category. Where effective rate of rearing recorded 84.00% compared to 76.00% in control, total haemolymph protein mg/ml. recorded 70.54mg/ml. compared to 64.52mg/ml. in control and number of eggs / female recorded 284.00 compared to 262.00 in control. Cocoon indices were 1.165 g, 0.229 g and 19.66% for cocoon, cocoon shell weights and cocoon shell ratio comparing to 1.067 g, 0.169 g and 17.71% for the control, respectively. | ||||
