摘  要:
通过对山东大蔡牧业集团有限公司种鸡场(2008年5月—2009年4月)孵化生产记录数据进行整理、归纳和汇总,对种蛋受精率、受精蛋孵化率和健雏率3个指标进行相关统计分析,计算两两之间的相关系数,并建立回归方程。结果发现:种蛋受精率和受精蛋孵化率的相关系数r=0.9223(P<0.01);种蛋受精率和健雏率的相关系数r=0.4097(P<0.05);受精蛋孵化率和健雏率的相关系数为r=0.3980(P<0.05)。

摘  要:
It was summarized the production record data from Chicken farm of Shandong Dacai Animal Group Co.Ltd. in May 2008 to April 2009.The correclation among the hatching egg fertilization rate, the hatching rate and the rate of healthy chickens were analysised. The correlation coefficient between them was calculated.The regression equation was established.The results showed the correlation coefficient between hatching egg fertilization rate and hatching rate were r=0.9223 (P<0.01),the correlation coefficient between fertility rate and the rate of healthy chicks were r=0.4097 (P <0.05),the correlation coefficient between hatching rate and rate of healthy chicks were r=0.3980(P<0.05).
