不同断喙方式对青年后备蛋鸡生长发育的影响

Effect of Different Beak Trimming on Growth Performance of Replacement Layer in Growing Period

选择国内饲养量最大的海兰褐壳商品蛋鸡为研究对象,采用Nova-Tech红外断喙器不同断喙模块和强度对鸡只进行断喙处理,同时以不断喙和传统热刀断喙为对照组。定期收集青年后备鸡不同组别鸡只生长和16周龄龙骨发育数据进行统计分析。结果表明:红外断喙模式对鸡前期发育有一定影响,但是随着鸡生长,红外-浅断喙模式越来越表现出较好的生长发育性状。

Hy-line brown commercial layers,which share the largest market in China,were selected in this study.The layers were treated by Nova-Tech IRBT machine with different module and intensity,comparing with no beak trimming and hot blade group. Development information in growing period and keel score at 16 weeks of age were collected and analyzed regularly. The results showed that IRBT had a little influence on the early growth of the layer,but with the development,layers in IRBT group showed better growth performance.
