가잠의 인공사료육에 있어서 사료조성차이와 환경조건이 누에의 성장발육에 미치는 영향

Effect of the Difference of Dietary Composition and Environmental Condition on the Growth and Development of Silkworm, Bomby mori L., fed on Artifial Diet

인공사료육 누에에 있어서 사료조성 차이와 사육환경이 누에의 성장발육에 미치는 영향은 다음과 같다. 1. 사료의 대두분말 함량이 많을수록 경과가 짧았으나 대두분말 함량이 50%를 넘으면 오히려 경과가 길어졌다. 2. 감잠비율은 대두분말 함량비가 50%까지는 영향을 미치지 못하지만 그 이상에서는 높았다. 3. 사료조성 차이가 견질에 미치는 영향은 단견중에 있어서는 단백질 함량이 많을수록 무겁고 견층중은 차이가 없었으며 견층비율은 대조구에 비해 각 처리구 모두 낮았다. 4. 사육환경 중 온도는 고온이 광선은 암조건이 경과를 단축시켰다. 5. 감잠비율은 치잠기 고온에서 낮았고 광선은 암조건에서 낮았다. 6. 사육환경이 견질에 미치는 영향은 단견중, 견층중, 견층비율 모두 온도는 고온이, 광선은 암조건이 양호하였다.

This study was carried out to investigate the effect of the difference of dietary compositions and environmental conditions on the growth and development of silkworm. The results obtained are as follows: 1. The more amount of soybean meal of diet was added, the more duration of the larval period was shortened. But Fifty percent increase of the amount of protein of diet leongthened the duration of larval period. 2. Fifth percent addition of the soybean meal to the diet does not influence the silkworm mortality, Whereas more than that gives rise to the adverse effect on the silkworm mortality. 3. The cocoon quality was significantly affected by the difference of dietary compesition. 4. In the environmental condition the duration of larval period was shortened in the high temperature and the dark condition. 5. The silkworm mortality was increased in the high temperature and the light condition. 6. The cocoon quality was significantly affected in the high temperature and the dark condition.
