摘要：

为研究蝇蛆粉对蛋鸡免疫力和生产性能的影响，选择3000只星杂288蛋仔鸡，进行为期6周饲养实验（试验I）；选择3000只生产期星杂288蛋鸡，进行为期3个月饲养实验（试验II），根据蛋白饲料的不同又分为试验组（蝇蛆粉型日粮）和对照组（鱼粉型日粮）。结果显示，试验I中，试验组与对照组相比，每吨食粮降低原料成本约60元，成活率提高3.2%（P<0.05），均匀度提高8%（P<0.05）；试验II中，在试验期内产蛋数提高9.2%（P<0.05），蛋重提高9.616%（P<0.05）。与对照组相比试验组T-淋巴细胞、B-淋巴细胞的数量均有不同程度的增加。生产蛋鸡免疫球蛋白IgG提高9.5%、IgM提高7.1%。因此蝇蛆粉代替鱼粉饲喂蛋鸡是合理利用饲料资源、降低生产成本、提高经济效益的有效途径。

Abstract:

To investigate the influence of Maggots powder on immunity and performance of Laying Hen. Experiment I：3000 Xingza 288 egg-chickens were randomly allotted to two groups，were fed with the diet with maggots powder (the maggots group) and fish meal (the control group) respectively for 6 weeks. Experiment II: 3000 Xingza 288 Laying Hen were randomly allotted to two groups, were fed with the diet with maggots powder (the maggots group) and fish meal (the control group) respectively 3 months. The results showed that in Experiment I, contrast with the control group the diet cost of the maggots group were decreased 60 yuan/t, survival rate of egg-chickens was increased by 3.2% (P<0.05), uniformity was increased by 8% (P<0.05). In Experiment II, contrast with the control group laying member and the weight of eggs was increased by 9.2% (P<0.05) and 9.616% (P<0.05) respectively. Contrast with the control group the members of T-lymphocytes and B-lymphocytes of egg-chickens and layers were increased. Contention of IgG and IgM of layers were increased by 9.5% and 7.1% respectively. The results indicated that supplementation of maggots powder in diet of laying hens was feasible.
