鲜蛆替代国产鱼粉对海兰棕壳蛋鸡产蛋性能的影响

The Effects of Fresh Maggots Replacing Domestically-made Fish Meal as Fodder Content on Egg Production of Hu-Line Brown Laying Hens

目的 :观察猪粪饲养的蝇蛆替代国产鱼粉作饲料对海兰棕壳蛋鸡产蛋性能的影响。方法 :用猪粪饲养蝇蛆 ,收集 3龄鲜蛆直接替代国产鱼粉饲养 4 0周龄海兰棕壳蛋鸡 ,设不同量鲜蛆替代组和鱼粉对照组 ,观察蛋鸡的日平均产蛋率、日平均产蛋量和平均蛋重 ,记录饲料消耗量和蛋鸡死亡数 ,用SPSS统计软件分析结果。结果 :用鲜蛆蛋白半量替代饲养蛋鸡 ,蛋鸡产蛋能力优于常量国产鱼粉蛋白饲养 ,用鲜蛆等量和低于半量鱼粉蛋白量饲养蛋鸡 ,能取得与常量鱼粉蛋白相同的饲养效果。用猪粪饲养的鲜蛆直接饲养蛋鸡不会增加疫病的发生。结论 :鲜蛆饲养海兰棕壳蛋鸡的产蛋性能优于国产鱼粉 。

Objective:To observe the effeets of fresh maggots replacing domestically made fish meal as fodder contant on egg production of Hu line brown laying hens.Methods:Replacing domestically made fish meal in diet of 40 week old hens with fresh maggots cultivated in pig manure at different amounts and observations were made on egg production,including the average egg laying rate per day,the average egg production rate per hen on per day, and the average weight of each egg.The data recorded were compared with those of hens reared with regular fish meal and analyzed with SPSS statistically.Results:Using maggot replacement,especially,when half protein amount was replaced,better egg peoduction was obtained,comparing with the regularily reared hens.The usage of maggots that had not been washed or sterilized didn't cause any disease of hens.Conclusion:Rearing Hu line Brown laying hens with maggots cultivated in pig manure could get better results than rearing with domestically made fish meal.These maggots could be used directly without washing or sterilization.
