为探讨黄麻羽肉用种鸡的体质量、体尺、开产日龄与产蛋量的相关关系,选取同一批次、健康状态相近的20周龄黄麻羽肉用种鸡270只（公母比1∶2）,测定体质量、体尺,记录各母鸡的开产日龄和开产后连续127 d的产蛋量,对各指标进行相关性分析,并对产蛋量和与之显著相关的指标进行回归分析。结果表明:黄麻羽公鸡的体质量、胫长、胫围、龙骨长、体斜长、胸宽均极显著高于母鸡的（P

The study was carried out to investigate the correlation between the body mass,body size,age at first egg and egg production of jute broiler.Two hundred and seventy healthy jute broiler(male to female ratio 1∶2)at the same batch of incubation were selected at 20 weeks old.The body mass,body sizes,age at first egg and egg production of the birds were measured and the indexes correlation was analyzed.Meanwhile,regression analysis was performed on egg production and its significant correlation indexes.The results showed that the body mass,shin le...
