Fertilizing capacity of three boars from different breeds; Meishan, Landrace and Large White; were tested. Semen quality was macroscopically evaluated. A direct observation of embryonic quality were performed after surgical collection from natural mated gilts. A total of nine gilts, equally divided into three groups was used in this experiment. Each group was mated with each boar. The result showed that there was a relationship between a quality of semen and a quality of recovered eggs. High percentage of fertilized eggs (90%) were obtained in each gilt and the stage attained was related to the day of collection. The method will be useful to confirm the semen quality in boar.
