摘要: 以海兰褐蛋种鸡为观察对象,从122日龄开始到429日龄结束,收集7 520只蛋种鸡1个产蛋年(2014年1月—12月)的产蛋资料,分析得出每月的产蛋率、破蛋率等相关数据,对12个月的数据进行统计分析。结果表明,产蛋率以春季最高,秋季最低;种蛋合格率冬季最高,秋季最低;料蛋比以冬季最高,春季最低;破蛋率以夏秋两季最高,冬季最低;死淘率以秋季最高,冬季最低。

Abstract: The data of egg production of 7 520 breeding Hy-Line Brown laying hens from January to December of 2014 (122-day old to 429-day-old) were collected and statically analyzed. The highest laying rate in 2014 was observed in spring and the lowest rate was observed in autumn. The highest qualified rate of hatching egg was observed in winter and the lowest rate was observed in autumn. The highest feed to egg ratio was observed in winter and the lowest ratio was observed in spring. The highest broken egg rate was observed in summer and autumn, and the lowest rate was observed in winter. The highest mortality was observed in autumn and the lowest mortality was observed in winter.
