肉种鸡育成期笼养效果的研究

本研究就艾维茵肉用种鸡在育成期笼养的效果进行了观察。比较和分析了在笼养和平养时其体重、增重、育成率、淘汰率和鸡群的均匀度的变化。结果表明，笼养和平养的效果无显著差别，在鸡舍的环境卫生控制和管理上，笼养明显优于平养。而且有效地控制了球虫病的发生。但其缺点是在调鸡和称重时对鸡的损伤程度大，不过在管理上可以避免。本研究认为艾维茵父母代种鸡在育成期实行笼养是可行的。

Study of the Cage Beeping Effect on Broiler Breeder Growth during Rearing Stage

The offect of Avian broiler breeder raised in cage during rearing stagewas observed in this study. Measurements in body weight,gain in weight,survival abil-ty,rate of cull and uniformity were compared and analized between cage,beeping andscattered-beeping treatments.The result showed that there were no significant differ-ences between treatments.The cage beeping was obviously superior to the scatter-beeping in both control of environmental hygiene and management of bird's house,alsothe occurrence of cocidiosis was curbed effectively.Its defect was that the degree of dam-age to birds was a little higher during adjusting and weighing,Therefore the conclusioncould be reached that Avian stock broiler breeder could be raised in cage during rearing stage.
