摘要
木胸肌病和腿软是肉鸡养殖业中的严重问题。鸡栖息地中光线的颜色和强度会影响雏鸡的行为,包括行走。本研究旨在确定周期性和局部光照切换是否会诱导肉鸡运动并影响其木胸肌病和腿软症。30 只五天大的肉用仔鸡被分配到两个鸡栏(每个鸡栏 4.72 m × 0.73 m)。在对照栏中,雏鸡在三盏白光发光二极管(LED)灯下饲养至 42 日龄。在另一栏中,雏鸡在位于中间的白色 LED 灯下饲养,同时在栏的两侧辅以蓝色或红色 LED 灯。LED 灯的颜色每 3 小时变换一次,从蓝色和红色到红色和蓝色。从 21 日龄开始,所有的 LED 灯都更换了颜色,每 3 小时只打开一侧的灯。周期性和局部颜色切换以及开关灯能明显诱导肉用仔鸡运动。木质胸评分在光照切换处理后趋于改善。胫骨长度、直径和断裂强度没有受到明显影响。这是首次报告表明,通过周期性和局部光照切换可诱导肉用仔鸡运动,这可能有助于改善肉用仔鸡的健康状况。
Periodic and Local LED Light Switching Induces Broiler Locomotion.
Wooden breast myopathy and leg weakness are serious problems in the broiler chicken industry. The color and intensity of light in the chicken habitat affect behavior, including walking of chicks. The present study was conducted to determine whether periodic and local light switching induces locomotion and affects wooden breast myopathy and leg weakness in broiler chicks. Thirty five-day-old broiler chicks were assigned to two pens (4.72 m × 0.73 m each). In the control pen, chicks were reared under three white-light emitting diode (LED) lights until they were 42 days old. In the other pen, chicks were reared under a white LED light located in the center, supplemented with blue or red LED lights on either side of the pen. The color of the LED lights changed every 3 h, from blue and red to red and blue. From 21 d of age, all LED lights were changed and only one of the side lights was turned on every 3 h. From 35 d of age, all three white lights were turned on until 42 d of age. Periodic and local color switching and on-off switching significantly induced locomotion in broiler chicks. Wooden breast scores tended to improve with light-switching treatment. The tibia length, diameter, and breaking strength were not significantly affected. This is the first report showing that locomotion may be induced in broiler chicks by periodic and local lighting switching, and may be useful for improving the health status of broiler chicks.
