This study evaluated the quality of ejaculated from adapted breeds of goats as the morphologic aspects,functional and thermoresistance. An aliquot of the pool of each breed was used for morphological evaluation bywet preparation, quantifying sperm defects and dividing them into classes. The samples were cryopreservedusing TK3000 machine and evaluated by thermoresistance test by checking motility and sperm vigor every hour.For plasma membrane functionality analysis, was used hiposmotic test. There was no difference (P > 0.05)between the breeds in all sperm defects before and after cryopreservation, as well as for the thermoresistancetimes for motility and sperm vigor (P > 0.05). There was a significant reduction in motility and sperm vigor 120minutes after thawing of the samples. There was no difference (P > 0.05) between the percentage of sperm withfunctional membrane between the evaluated breeds. Therefore, the evaluated breeds have morphology,functionality and similar sperm thermoresistance.(AU)
