Influence of different varieties of mulberry leaves (Morus alba) on growth and cocoon performance of biovoltine strain of silkworm (Bombyx mori)
Abstract
The influence of different varieties of mulberry leaves used as feed on mortality and cocooning of silkworm as well as on cocoon qualities (good cocoon, flimsy cocoon, stained cocoons, cocoon shell weight and pupa weight) were examined. Their influence on oviposition, Eggs fertility and hatchability were also examined. The effects of anti nutrients presents on the variety mulberry leaves used as feed on silkworm performance were further examined. The result revealed that there were significant differences (P ≤ 0.05) between varieties of mulberry leaves used as feed on mortality of larva and cocooning, while its influence on good cocoon, flimsy cocoon, stained cocoons, cocoon shell weight and pupa weight, oviposition, egg fertility and hatchability were not statistically significant (P ≥ 0.05). It was also observed that K2, variety has the lowest antinutrient components while S25 has the highest antinutrient component.
