【摘要】 对AA+肉用种鸡产蛋周(1～35周)的产蛋率、受精率、孵化率进行跟踪观测并对3个指标进行相关性分析。结果表明:产蛋率与受精率相关系数为0.864(P<0.01);产蛋率与孵化率相关系数为0.900(P<0.01);受精率与孵化率相关系数为0.992(P<0.01),产蛋率与受精率,产蛋率与孵化率,受精率与孵化率三者都呈较强正相关。其中受精率与孵化率相关性最强,产蛋率与孵化率相关性次之,产蛋率与受精率相关性较弱。更多还原

【Abstract】 This experiment observed the AA+ meat chicken’s laying rate,fertilization rate,hatching rate from first to thirty-fifth week,and analyzed the correlation of three parameters. The results showed that the correlation coefficient of laying rate and fertilization rate was 0.864 (P<0.01),the correlation coefficient of laying and hatching rate was 0.900 (P<0.01),fertilization and hatching rates’ correlation coefficient was 0.992(P<0.01),laying rate with fertilization rate and hatching rate,fertilization rate and hatching rate had strongly positive correlation. The correlation between fertilization and hatching rate was significant(P<0.01) and weaker was laying rate and hatching rate.The correlation between laying rate and fertilization rate was the weakest.更多还原
