雉鸡行为与对饲养环境适应的研究

Pheasant′s behaviors and their adaptabilities to artificial environment

１９９３年４月～１９９６年４月，笔者对雉鸡行为进行了３年的观察．结果表明，人工定向选择使驯养雉鸡摆脱了自然选择的压力，某些行为与野雉有了明显的不同，出现生长不足（驯化雉表现的某些行为模式较野雉少）或生长过度（驯化雉表现的某些行为模式加强）现象．人工驯养使雉鸡的警卫和逃避行为减弱，取食和产卵行为加强，雉鸡对人工环境的适应逐代加强．

A careful observatin about the ring necked pheasant′s(Phasianus colchicus torquatus)behaviors was carried out for more than three years from 1993 to 1996.The results show:the artificially directed selection lets tame pheasants shake off the pressure from the natural selection.Some behaviors of the tame pheasants show great difference from those wild ones under developed (there are less behavior patterns than wild ones)or over developed (Some behavior pattern is strengthened compared with wild ones).Aritificial raising and training weaken some behavior such as vigilance and escaping ,but strengthen feeling and producing .The ring necked pheasants have greatly improved their adaptabilities to the artificial environment generation after generation.
