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.
