摘要
本文对成都动物园圈养条件下鸳鸯的自然繁殖和行为进行了观察,结果表明:巢箱要求放置不是太高,只要光线较暗或比较隐蔽即可;声音对圈养条件下鸳鸯的繁殖干扰不大;在发情和育雏期间应适当增加动物性蛋白饲料;断翅后的鸳鸯受精率略低于未断翅鸳鸯。
Natural reproduction and behavior of mandatin duck raised in captivity were observed at Chengdu Zoo. The results suggest that the cage should not be placed very high, but with concealment or in a weak light; noise does not make much disturbance to the reproduction; food with properly increased animal protein should be provided to those at oestms or with nesting birds; those with broken wings have a little lower fertilization rate than that of normal birds.
