This study evaluate the effect of melatonin supplementation to TRIS-GEMA diluter in plasmatic andmitochondria membrane integrity of semen ram cryopreserved. Was used seven ejaculates of six ram,whichwere pooled in pool, according to the experimental groups: Control; T1 - 1x10-7 mol / L and T2 - 1x10-9 mol / Lmelatonin. Posteriorly the diluting the samples were packaged in straws of 0.25 ml and cryopreserved. Afterthawing at 37°C for 30 seconds, the samples were analyzed for Test thermoresistance slow (TTR) andacrosomal membrane integrity. For statistical analysis we used the Duncan test (α = 0.05) for meancomparison. Treatments 1 and 2 differed statistically control for plasma membrane integrity at times 60, 120and 180min. It was concluded that supplementation 1x10-7mol / L and 1x10-9mol / L of melatonin increased theintegrity of the plasma membrane to 60,120 and 180 minutes.(AU)
