This study aims to evaluate the fertility rate of sheep semen diluted and cooled to 4ºC in powdercoconut water (ACP-102®) with and without egg yolk in artificial insemination by cervical route in sheep. Tworam lambs and 72 ewe lambs were used, divided into 3 groups: ACP-102® without egg yolk and cooled to 4ºCfor 12 hours, ACP-102® with 2,5% egg yolk also cooled as the first group and a control group with fresh semendiluted in ACP-102® without egg yolk. Pregnancy diagnosis was performed 30 days later. Pregnancy rates weresignificantly different (P < 0.05) between ACP-SGF (58,3%) and ACP-SG4 (20,8%) groups. The ACP-CG4(37,5%) group did not differ in relation to the ACP-SGF. Therefore, the addition of egg yolk to ACP-102®extender favors the viability of sheep semen, cooled to 4ºC for 12 hours and fertility of artificially inseminatedsheep by cervical route.(AU)
