Effect of protection and refrigeration time alteration on hatching rate of acid-treated silkworm (Bombyx mori) eggs
摘要
Abstract
[Objective]The present experiment was aimed to investigate the effect of altering protection and refrigeration times outside storeroom on hatching rate of acid-treated silkworm (Bombyx mori) eggs. [Method]The hatching rate of acid-treated eggs (in HCl solution, 48℃), obtained from the cross and reciprocal cross species of silkworm variety Liangguang 2, was investigated after protecting them outside storeroom at 25℃ for 2-7 days and refrigerating at 3-5℃ for 30-110 days. [Result]The growth in the eggs kept for same refrigeration time was found faster in shorter protection time treated eggs compared to those kept for longer protection time. Further, the uniformity of hatching was lesser in those eggs which have been kept for longer protection time. While the practical hatching rate increased significantly in silkworm eggs kept for different protection time and the longer refrigeration duration. The hatching rate increased to more than 90％ after refrigerating the eggs for 70 days, which was equal to the production demand, also the hatching uniformity of eggs was improved. [Conclusion]The age gap in silkworm eggs and insufficient refrigeration times results in irregular hatching, therefore, the pre-hatching protection and refrigeration times must be manipulated as much as possible for preventing irregular hatching uniformity of silkworm eggs.关键词
