Abstract

Aiming to evaluate frozen goat semen in TRIS diluent with low egg yolk addition, progressive motility was evaluated soon after freezing and again 4 years later, resulting in 38.2 ± 7.4% and 31.4 ± 13.5%, respectively. Sixteen goats were oestrus synchronized through progesterone impregnated intravaginal sponges followed by PMSG injection on day 9. Vaginal sponges were withdrawn on day 11, with goats being artificially inseminated 46 hours later with semen frozen in straws and stocked during 4 years in liquid nitrogen. The nonreturn rate attained 31.2%. TRIS diluent with low egg yolk addition was considered as efficient in relation to frozen sperm evaluated both in vitro through progressive motility as in vivo through artificial insemination.
