This work aimed to evaluate the quantitative parameters of fresh and thawed sperm of Canindé goats in theState of Piauí. Ten sperm samples were collected, using artificial vagina, from four goats at reproductive age. Eachejaculate was evaluated for volume, sperm concentration, mass motility, total and progressive motility, percentage ofmotile spermatozoa and vigor, for further dilution in ACP-101. Then, the sperm was filled in 0.25 mL straws,cryopreserved using the TK3000 machine and stored in nitrogen cylinders at -196 °C, for further analysis at SCA. Thesperm parameters were submitted to the T test for comparison between the fresh and thawed groups. The values forfresh sperm relative to total and progressive motility, vigor and sperm viability were higher (P < 0.05) whencompared to thawed, although both fresh and thawed sperm of these animals could be used in programs of artificial insemination (IA).(AU)
