Abstract The goal of this study was to assess effect of three Tris-extender types, of egg yolk(E1),soy lecithin(E2),and coconut milk (E3),on sperm characteristics of Holstein bull semen at freezing stages. Semen was collected and pooled on each collection day. Semen should have good mass motility ≥70%. The pooled semen was divided into three divisions; E1: extended by E1: Tris-citric with 15% egg yolk; E2 and E3: diluted with 0.5% soy-lecithin and 15% coconut milk at a rate of 1:15,respectively |
