蝇蛹粉对蛋鸡产蛋性能及免疫力的影响

目的]探讨蝇蛹粉对蛋鸡产蛋性能及免疫力的影响。方法]选取240只京红1号褐壳蛋鸡,分为试验组和对照组2组进行饲养试验,在饲料中添加蝇蛹粉等量代替鱼粉,研究蝇蛹粉对蛋鸡生产性能、蛋品质以及3种免疫球蛋白(Ig A、Ig E和Ig G)浓度的影响。结果]试验组蛋重、日采食量、料蛋比均与对照组差异极显著(P0.01)。试验组蛋形指数、蛋黄相对比重与对照组均差异不显著(P0.05);试验组蛋壳相对比重与对照组差异极显著(P0.01)。蝇蛹粉对蛋鸡Ig E浓度的影响极显著(P0.01),而对Ig A和Ig G浓度的影响不显著(P0.05)。结论]蛋鸡日粮中添加蝇蛹粉等量替代鱼粉能够明显提高蛋鸡的生产性能及免疫力,降低蛋鸡的饲料成本,获得较好的经济效益,适宜推广利用。

Effects of Housefly Pupae Powder on Production Performance and Immunity of Laying Hens

Objective] To discuss the effects of housefly pupae powder on the egg production performance and immunity of laying hens. Method]240 Jinghong No.1 brown-shell laying hens were randomly divided into 2 groups(control group and test group) to conduct the feed-ing test.Housefly pupae powder was replaced by the same amount of fish meal to add in the feed .The effects of housefly pupae powder on the production performance,egg quality and the concentrations of three kinds of immunoglobulin(IgA,IgE,IgG) of laying hens were studied.Re-sult]The egg weight,daily feed intake,feed-egg ratio in test group had extremely significant differences with control group (P <0.01).The egg shape index and relative proportion of egg yolk in test group had no significant difference with control group(P>0.05).Relative proportion of egg shell in test group had extremely significant difference with control group (P<0.01).Housefly pupae powder had extremely significant effects on IgE concentration in laying hens (P<0.01),but it had no significant effect on the concentrations of IgA and IgG(P>0.05).Con-clusion]Adding the same amount of pupae powder in the diet of laying hens in replacement of fish meal could obviously improve the production performance and immunity of laying hens, and it could reduce costs.Better economic benefits could be obtained.It was reasonable and suitable for application.
