鸸鹋卵人工孵化初探

对1998～2002年哈尔滨北方森林动物园鸸鹋卵人工孵化条件进行综合分析,以初步确定鸸鹋人工孵化的适宜条件,结果表明,卵型指数为1.52～1.56的鸸鹋卵,孵化温度控制在36.5～37.4℃,孵化湿度为50%～61%,孵化期失重在10%～15%之间能获得最佳孵化率和健雏率。Hoty方程计算出鸸鹋卵特异系数CSS为0.000565(n=60)。鸸鹋卵平放180°,每2h翻1次卵,晾1次卵,翻卵角度为90°能明显提高鸸鹋出雏率和健雏率,及时熟练的人工助产是避免鸸鹋后期死亡的重要手段。

Preliminary Study on Artificial Incubation of Emu Eggs

The research were conducted on the artificial incubation conditions of Emu eggs in the Harbin zoo from 1998 to 2002. The results revealed that the incubation temperature of eggs which the shape index is 1.52 to 1.56 should be controlled between 36.5℃ and 37.4℃, moisture 50% to 61% and weight-losing rate 10% to 15% in this stage to obtain the best hatching rate and healthy chick rate. The coefficient of superfine species(CSS) was calculated by Hoty equation with a value of about 0.000565(n=(60).) The Emu eggs could be got higher hatching rate and healthy chick rate if the eggs were laid flat 180°, and turned over with the angle of 90°and cooled in the air for every two hours. Punctual and skilled artificial aiding-birth are important steps to avoid rearing death of Emu.
