| 摘要: |
| 对引自南非的30只蓝颈鸵鸟（♀）在陕西关中地区的产蛋性能进行了研究，探讨了蓝颈鸵鸟在产蛋高峰期来临之前的产蛋规律。结果表明：4,5,6龄鸵鸟每只每年分别平均产蛋（42.1±20.8）,（47.0±21.4）,（53.8±19.5）枚，变异系数分别为49％，45％和36％，产蛋性能的重复力分别为为0.310 2，0.152 0和0.104 8（P<0.05）。年龄段间产蛋性能的变异程度较大。3年来每只鸵鸟每年平均产蛋（47.6±20.9）枚，变异系数为43％。每年的产蛋高峰期为5,6月，低峰期为7,10月。经产母鸟通常每窝产蛋12～20枚，休息7～14 d后进入下一个产蛋周期。 |

| Abstract: |
| The laying laws and the affecting factors to blue-neck ostriches were investigated by studying the egg producing ability of 30 blue-neck Africa ostriches before the high peak yield in life in Guanzhong,Shaanxi.The result showed that the average eggs of 4,5,6 year-old laying ostrichs were (42.1±20.8),(47.0±21.4),(53.8±19.5),the variation coefficient was 49%,45%,36%.and the repeatability was 0.3102,0.1520,0.1048 (P<0.05).The degree of variation of egg producing ability is significant.The average eggs in 3 years in Guanzhong were (47.6±20.9).The variation coefficient was 43%.The high yield peak was in May and June.The low yield peak was in July and October.The number of eggs of a multiparty blue-neck ostrichs was 12-20 once,then they will lay eggs after 7-14 days. |
