不同比例麦麸和玉米秸秆对黄粉幼虫生长性能的影响

为研究不同比例麦麸和玉米秸秆对黄粉幼虫生长性能的影响,试验选择1000只5~6龄黄粉虫,随机分成5组,对照组饲喂小麦麸,试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别饲喂20%麦麸和80%玉米秸秆、40%麦麸和60%玉米秸秆、60%麦麸和40%玉米秸秆、全玉米秸秆。结果表明,与对照组相比,试验Ⅰ、Ⅳ组的体重、体长和粗蛋白质含量显著降低(P<0.05),试验Ⅱ、Ⅲ组黄粉幼虫体重、体长和粗蛋白质含量差异不显著(P>0.05),且试验Ⅱ组的经济效益每千克提高了15.15%。因此,试验Ⅱ组麦麸和玉米秸秆的比例最适合养殖黄粉幼虫。

Effect of Different Proportion of Wheat Bran and Corn Straw on the Growth Performance in Yellow Powder Larva

In order to study the effect of different proportion of wheat bran and corn straw on the Yellow powder larva growth performance trait, 1000 5 to 6-age Yellow powder larva were selected and randomly divided into five groups,the control group was fed wheat bran, testⅠ,Ⅱ,Ⅲ and Ⅳ groups were fed 20% wheat bran and 80% corn straw,40% wheat bran and 60% corn straw,60% wheat bran and 40% corn straw and corn straw, respectively. The results indicated that body weight, body length,protein content of the testⅠ and Ⅳ groups were significant differences compared with the control group (P<0.05). The body weight, body long,the protein content of test Ⅱ and Ⅲ groups were no significant differences compared with the control group(P>0.05),and economic benefits of test Ⅱ group increased by 15.15% per kilogram. Therefore,wheat bran and corn straw ratio in test Ⅱ group was the most suitable for breeding of Yellow powder larva.
