摘要
试验结果表明:以麦麸、玉米粉混合饲料及猪粪育蛆,其饲料系数分别为167和293。以猪粪育蛆,麦麸和玉米粉用量减少近80%,育蛆成本比前者降低60%左右。以蛆饲喂出壳一个月内的稚鳖,其平均增重量约为饲喂鸡蛋黄稚鳖的38倍。两组试验中,稚鳖平均增重量,经T测验,差异极显著。以猪粪育蛆,并以蛆饲喂稚鳖,既处理了猪粪,减少环境污染,又提高了猪粪的经济价值,值得在养殖业中推广应用。
Houes fly maggots were grown on the mixture containing wheat bran, maize meal and porcine manure. Their forage coefficient was 1.67 and 2.93, respectively. The consuming amount of wheat bran and maize meal in porcine manure could be decreased by about 80%. Using porcine manure as forage, the production cost of house fly maggot could be decreased by 60% or so. The average increased weight of l month young Trionyx sinensis after hatching feed with house fly maggot was about 3.8 times as compared with that feed with egg yolk. T test revealed that the divergence of the two experiments was approximately remarkable. Utilizing porcine manure to raise house fly maggot and feeding l month young Trionyx sinensis with the maggot can not only reduce the environmental polution but also improve the economic value of porcine manure. Thus, this technique is worth popularizing in breeding field.
