摘要
蓝蓑羽鹤主要分布于非洲南部,北京动物园2001年开始饲养展出,2005年繁殖成功。在我国北方饲养蓝蓑羽鹤冬季需要保温设施,还需要适当的耐寒训练,提高对寒冷的适应能力。蓝蓑羽鹤选择植物性食物多,全年在繁殖期和非繁殖期饲料蛋白含量分别为34.9%和21.6%,平均能量16.6kJ/kg。精液澄清、透明。雌鹤性成熟年龄早于雄鹤。北京地区繁殖期3～6月,平均窝卵数2枚。雏鹤生长高峰期在35～60日龄。
The blue crane,Anthropoides paradisea,is naturally distributed in South Africa,however a breeding program was started at the Beijing Zoo in 2005 after being transferred from Belgium in 2001.Heat was needed for this bird in winter,but the withstanding cold training was also needed for them to adapt to the cold weather in Beijing.They preferred a more vegetarian diet.Protein content of the diet during the breeding season and non-breeding season are 34.9% and 21.6% respectively and the average energy is 16.6 kJ/kg.The semen is pellucid and translucent.Females reach sexual maturity earlier than males.In Beijing,the breeding season is from March to June with a clutch size of 2.The period of 35 to 60 days is peak of physical development of the young.Artificial insemination can be used to improve the reproduction rate of blue cranes.
