摘　　要：Growth indicators including weight, body length, wings length, tail length, tarsus, gape, the third toe and head width of 21 nestlings of Great Bustard (Otis tarda) were measured and investigated in Harbin Zoo, Harbin, China during 1999-2002, and methods on successfully fostering nestlings of the bird were also summarized in this article. The results showed: the Great Bustard is a kind of premature bird and its birth weight was 86.31?.56g (N=21); environmental temperature for the neonatal nestlings should be controlled at 36C; the feeding principle having many meals but little food at each for the nestlings should be followed; since six weeks after birth, nestlings of both gender began to show significant difference in body weight, the weight of male was 1.8 times of that of the female after fourteenth week, and by weight and body figure sexual identity could be easily discerned when 3 or 4 months old; There is no significant difference in growth and development of all organs between male and female nestlings and organ growth curves were fit into Logistic equation.1999-2002年在哈尔滨动物园对21只健康成长的笼养大鸨(Otis tarda)雏鸟进行了人工育雏的研究,总结出成功的育雏方法和经验,并对雏鸟生长发育的各项生理指标如:体重、体长、翅长、尾长、跗蹠、嘴裂、中趾及头宽进行了测定,结果表明:大鸨为早成鸟,其初生体重为86.31+3.56g(n=21),其新出雏雏鸟的环境温度控制在36℃,以后每天降低一度,大鸨的饲喂实行少吃多餐的原则,雏鸟生长发育中雌雄体重从第六周有明显差异,第十四周雄鸨体重是雌鸨体重的1.8倍,可以从体形上明显区别雌雄;雌雄各器官的生长发育差异不显著;大鸨雏鸟各器官的生长符合Logistic曲线增长。
