Abstract: The objective of this study was to evaluate the effect of antioxidant Reveratrol added to semen cryopreservation extender, on the maintenance of post-thaw sperm motility. Ejaculates from two bucks of American Alpine breed were evaluated and diluted to contain 400 x 106 cells/ml, in Tris-egg yolk extender and supplemented with Resveratrol (4, 6 or 8 ?g?ml), or no antioxidant (control). The semen was loaded into 0.25ml straws, cooled and frozen in a programmable freezer and stored in liquid nitrogen. The supplementation of extender with 4 and 8 mg/ml Resveratrol had a significant (P&lt0.05) effect on post-thawingsperm motility and TDM, when compared to the control, indicating that the antioxidant was able to protect sperm membranes during the cryopreservation process.  aAnimal production  aResveratrol  aAntioxidante  aCaprino  aCriopreservação  aDescongelamento  aEspermatozóide  aProdução animal  aSêmen  aMotilidade  aMotility1 aMEDEIROS, I.
