The objective was to evaluate the use of the hot plate to replace the water bath in the thermo resistance test of ovine sperm after cryopreservation. Ten ejaculates were also collected from three adult sheep (n=30), by means of artificial sheep vagina. The collected samples were diluted in Tris-Egg Yolk, at a final concentration of 200 x106 sptz/mL and subjected to a cooling curve for subsequent cryopreservation in liquid nitrogen straws. Immediately after thawing, the samples were analyzed for membrane and acrosome integrity, and mitochondrial activity. The semen was then divided into two tubes and submitted to TTR, one in a water bath and the other in a hot plate, and evaluated every 30 minutes, from time zero (post-thaw) until 90 minutes...
