Effect of Acetic Acid Ester and KUMGANG Medicine Stone in Silkworm Rearing with Artificial Diet and Mulberry
Raising silkworms by using artificial feed is not affected by the seasons and can realize the industrialization of silkworm breeding. The study has been conducted the research for using acetic acid as the material of organic acid in fresh mulberry and KUMGANG medicine stone in which various mineral salts are many contained as the material of inorganic salts in artificial feed. When acetic acid esterfied is added to artificial diet as rate of 3.3%, the setae dispersion within 48h was above 98% and the incentive was 100%. Antiseptic effect on artificial feed has been maintained for 90h since falling the feed. Acetic acid has raised the feeding habit on the 3rd instar larvae as the rate of 118.5% to128.4% and the body weight as the rate of 104.5%. KUMGANG medicine stone of the rate of 1% on artificial feed has promoted the growth and development of young silkworm. In the autumn with bad condition on rearing, KUMGANG medicine stone has been decreased the disease occurrence in larvae and raised the quality and yield of cocoon.
