Studies of Artificial Diets for Silkworm( I )(Basic Studies of the diets by wet storing)

잠아 인공사료에 대한 연구 제1보 사료장기저장에 대한 기초연구

This treatise was sat up as a basic study of the artificial diets of silk worm, both nursed and wild, by storing the natural leaves in defarmentizing solution and the results obtained were as followings. 1. Defarmentizer C, a kind of defarmentizer, was developed by the author in order to store any natural diet by soaking them in the solution. 2. The defarmentizer was workable for aerophobic bacteriums, but was not effectable for aerophilic bacteriums or fungus. 3. The defarmentized diet could feed silk worm during winter season. 4. The storing method has found the importance of growthness of the diet leaves and the perfect riped leaves were found as the best condition for the purpose. 5. The perfect riped leaves were softened properly during the soaking to be fed for silk worm. 6. The defarmentizing solution has held almost the same pH value of protein isoelectric point so that the protein extraction be ceased during the soaking process. 7. The utilization of defarmentizer has found an economical value. 5. The analytical results of various wild plant leaves were found to be usable as the artificial diet mixture for general silkworm.

본 연구는 잠아인공사료의 연구적일환으로서 사료저장에 대한 기초연구를 한것이며 실험결과는 다음과 같다. 1. 사료를 침적저장할 목적으로 Defarmentizer C.를 조성하였다. 2. 본 저장제는 호기성균을 억제할수 있으나 호기성균은 억제하지 못하였다. 3. 본 저장제는 사료를 무계절처리하여 동계 잠아사육이 가능하였다. 4. 본 사료저장법에서는 사료엽성숙도가 중요하며 완전히 성숙한 것이 안전하였다. 5. 완전히 성숙한 사료도 저장중 연화되어 잠아사료로서의 경도를 유지한다. 6. 본 저장제용액은 단백질등전점에 근접한 pH를 유지하여 사료단백질추출 억제되었다. 7. 본 저장제는 그 처리비용이 경제성을 유지하였다. 8. 인공사료재료로 사용할 야생식물엽의 조성분석결과는 그 사용가치가 인정되었다.
