不同饲养方式对蛋鸡生产性能的影响

Effect of feeding patterns on production performance in laying hens

为探讨不同饲养方式对蛋鸡生产性能的影响,试验选取24周龄产蛋率相近的海兰褐蛋鸡200只,随机分成2组,各组5个重复,每个重复20只鸡。把2组进行笼养和林地散养,除饲养方式外其他条件均相同。结果表明:(1)笼养组的存活率比林地散养组高出8%(P<0.05),笼养组的平均产蛋率比林地散养组高12.5%(P<0.05),笼养组的破软壳率比林地散养组高0.45%(P<0.05)。(2)笼养组的平均蛋重比林地散养组高3.71%(P>0.05),笼养组的平均日均采食量比林地放养组高2.02%(P>0.05),笼养组的平均料蛋比比林地散养组高1.07%(P>0.05)。总之,笼养蛋鸡的生产性能高于林地散养蛋鸡。但蛋鸡的不同饲养方式有着不同的经济效益。养殖户应该结合市场价格和需求,以及所饲养鸡的品种生活习惯选择最佳的饲养方式。

The purpose of this paper was to investigate the effect of feeding patterns on production performance in laying hens.A total of 200 Hyline brown laying hens were randomly divided into 2 groups with 5 replicates per group and 20 hens per replicate.The two groups were caged and dispersed in the woodland.All other conditions are the same except for the feeding patterns.The results showed as follows:(1)The survival rate of the caged group was 8%higher than that in the woodland group(P<0.05).The average egg production rate in the caged group was 12.5%higher than that in the woodland group(P<0.05).The rupture of the cage group was 0.45%higher than that in the woodland group(P<0.05).(2)The average egg weight of the caged group was 3.71%higher than that in the woodland group(P>0.05).The average daily intake of the caged group was 2.02%higher than that in the woodland group(P>0.05).The average egg to egg of the caged group was 1.07%higher than that in the woodland(P>0.05).In short,the production performance of the caged hens was higher than that of the woodland.But there were different economic benefits in different feeding patterns.Farmers should consider the market price and demand,as well as the breed and life habits of the hens to choose the best way to breed.
