| 摘 要： | 用精制程度不同，色泽自淡褐至白色，蛋白质含量分别为４２．４％（Ａ）、４８．９％（Ｂ）、５４．２％（Ｃ）和６５．８％（Ｄ）的４种脱脂大豆料，配制成人工饲料饲养小蚕。收蚁后２４小时疏毛率分别为５２．１％、８８．０％、１００％和９８．５％；收蚁后第１０日体重分别为０．２０４、０．２４５、０．２７４和０．２０９克，第１０日的存活率、三眠与四龄起蚕占蚕百分率均以含Ｃ饲料为最高，分别为９６．１％和６８．８％，而以含Ａ饲料为最低，仅为５４．４％和３８．９％。结果说明小蚕饲料用大豆粉以精制程度适中的淡黄白色Ｃ为最好。Ａ经甲醇、乙醇或水抽提后，蚕的疏毛率、存活率和生长发育速度均得到显著改善，其３种抽提物均对小蚕的取食和生长发育有阻碍作用。

| Abstract: | Four kinds of defatted soybean meal,which differed mainly in protein content andcolour (A: 42.4%,light brown;B: 48.9%, light brown; C: 54.2%, white yellow; D:65.8%,white),were used in the diets for rearing 1-3 instar larvae of the silkworm,Bombyx mori and the results were compared. Percentage of the larvae with dispersed se-tae 24 hours after hatching was 52.1,80.0,100 and 98.5%,and the mean weight of thelarvae 10 days after hatching was 0.204,0.245,0.274,and 0.209 gram for the four dietscontaining soybean meal A,B,C and D,respectively.The survival rate and the propor-tion of the larvae that reached the 3rd moulting stage 10 days after hatching were thehighest(96.1%and 68.8%respectively ) for the diet containing C,and the lowest(54.4%and 38.9%respectively)for the diet containing A.The result showed that themoderately refined C was the best one for young silkworm.It was demonstrated in thisexperiment that the setae dispersion,survival,and development of the early instar larvaereared on the diet of soybean meal A were improved significantly when the soybean mealhad been extracted with methanol, ethanol or water.Inhibitory effect of the 3 solventextracts on silkworm was also confirmed by adding each of them into the diet containingsoybean meal C respectively. |
