【摘要】 本文利用通径分析方法，对内蒙古畜牧科学院原种鸡场饲养的“星杂５７９”种鸡的与繁殖性能有关的性能间进行了相关剖析，分析其直接效应和间接效应，从而找出影响出健雏率的主要因素。通过对产蛋率、蛋重、受精率、受精蛋的孵化率、出雏率两两相关的分析及进一步的通径分析发现，受精率是影响出雏率的最重要因素，孵化率、产蛋率、蛋重对出雏率的影响依次减弱。更多还原

【Abstract】 This paper used path analysis to study the corelation ships between pro-duction performance and other factors of the" Xing Za 579”breeding hen correlativeanalysis was used to study these factors,analvzed direct and indirect reactions in orderto find the main factors affecting the healthy chick hatching rate.The results showedthat:(i)the tertitity rate is a major factor affecting the hatching rate,(ii)hatchability,laying rate and egg weight affect the hatchingrate with decreasing effects.更多还原
