家蚕原种人工饲料适应性及稚蚕饲料实用化研究

STUDIES ON THE ADAPTABILITY OF SILKWORM STRAINS TO ARTIFICIAL DIET AND THE PRACTICAL DIETS FOR REARING YOUNG SILKWORMS OF PARENTAL STRAINS

比较了现行蚕品种原种的人工饲料适应性，中系的Ｃ２７、８９５、２Ａ、８９１、菁松和日系的皓月、明珠、７５３２、１Ａ适应性较强；从脱脂豆粕粉的添加、脱脂菜籽粕粉的利用、生长促进物质和成型剂的改进等方面进行了研究，设计了现行蚕品种原种稚蚕实用化饲料配方，稚蚕人工饲料育的各项成绩达到或接近桑叶育水平，饲料与稚蚕用叶成本接近，基本达到实用化要求。

By investigating the adaptaility to the artificial diets in some commercial sikwormstrains ,it was observed that some races such as Qingshong , C27 , 895, 891 ,2A of Chi-nese strain and Haoyue , Ming Zhu , 752 , 1A,of Japanese strain had higher feeding ac-tivities than others. The practical diets for the young commerical parent strains were de-signed by adding moderate defatted soybean meals, making use of defatted rapeseedbrans and improving growth helping matters and shapitives.And rearing young parentsilkworms with the above artificial diets, both the cost and the results were similar tothose rearing with mulberry leaves, This rearing method could be considered to be feasi-ble and stable for the practical silkworm egg production.
