Abstract
|
|
|
Silkworm(Bomsix mori) were reared with modified artificial diets which were mixed with, as additives, leaf powders of Erigeron canadensis L., Cassia tora L., Cyperus anuricus Var. Laxus and Vigna Sinensis NEDL. The effects of additives on silkworm characteristics such as haemolymph, intestine, silkgland and electrophoretic zymogram and chemical characteristisc of tested plants were summarized as follows.
1. About 2∼5% addition on dry weight base of leaf powders of E. canadensis, C. tora, C. anuricus or V. sinensis to the basic artificial diet promoted feeding response and digestion and resulted in good practical silworm characteristics. The addition of V. sinensis and C. anuricus showed especially good effects.
2. The synergistic effect between different plant species was not recognized based on the feeding response and digestion of silkworm reared with various combinations of 2~4 different plant additives.
3. Electrophoretic zymograms of estrase, protease and phosphatase on haemolymph, intestine and silkgland were significantly different among treatments. In general, 1 or 2 more electrophoretic bands were detected when feeding response and digestion were promoted.
4. Contents of starch, crude fat, crude protein and inorganic base were apparently higher in the tested plants than in mulberry leaves. However, no volatile ingredent which is directly realted with feeding response was identified.
