| 摘 要： | 将308只淮南麻黄鸡按照20周龄体重以100g为组距从小到大分为5组,分析各体重组与开产蛋重及产蛋前期产蛋率、蛋重和种蛋合格率之间的关系,以确定淮南麻黄鸡20周龄体重的适宜选择标准.结果表明,20周龄体重与开产蛋重呈正相关,在22～35周龄,第3和4组的产蛋率增幅最大,维持时间较长；第1、2、3和4组蛋重增加比较平稳,第5组平均蛋重比第1、2和3组分别高11.05％、9.72％和8.61％(P＜0.05)；第3和4组的平均种蛋合格率较高,第3组的平均种蛋合格率比第1组高5.18％(P＜0.05).总体而言,第3和4组能够提供较多的合格种蛋数,淮南麻黄鸡的20周龄体重宜控制在1241～1 440 g之间. |
| 关 键 词： | 淮南麻黄鸡 产蛋率 蛋重 种蛋合格率 |

| Abstract: | In order to determine the suitable body weight at 20 weeks age,308 Huainan partridge chickens were allocated into five groups by group interval of 100 g based on body weight at 20 weeks age,and the relationships between weight of first egg,hen-day laying rate,average egg weight,percentage of setting eggs and body weight at 20 weeks age were analyzed.The results showed that,the correlation between body weight at 20 weeks age and weight of first egg was positive.The laying rates of group 3 and group 4 increas... |
| Keywords: | Huainan partridge chicken laying rate egg weight percentage of setting eggs |
