| Abstract: | 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. |
