摘要
应用相关及通径分析的方法研究了青海八眉猪繁殖性状间的相关关系,并分析了直接效应与间接效应及决定系数大小。结果表明:影响35日龄窝重的主要因素大小依此为35日龄仔数、20日龄窝重、初生窝重、产活仔数、产仔数、初生重。揭示了繁殖性状间的真实关系。
By using the method of correlative and path-coefficient analysis,the correlation among reproductive traits of Qinghai Bamei Swine were analyzed,and the direct effects,indirect effects and size of the decisive coefficient were analyzed.The results show that the main influencing factors for 35-day litter weight were 35-day litter size,20-day litter weight,birth litter weight,live litter size,birth litter size and birth weight in order.It were revealed the real relationships among reproductive traits.
