The objective was to evaluate the effect of re-freezing bovine sperm on the sperm quality of thawed semen. For this, the semen was thawed in water at 56 oC for 12 seconds to simulate a maximum seminal aggression, the contents of the straws were poured into test tubes to keep them tempered at 37 oC and incubated with 5 ml of Tyrode medium for 15 minutes. After this time, the microscopic analysis of the semen was carried out, two centrifugations were carried out 300 rpm / 5 minutes - 800 rpm / 10 minutes and the sperm concentration was determined with the help of a digital cell counter to dilute the semen; The stabilization and conditioning of the sperm was carried out at room temperature (14-20 oC) for 45 minutes and under ultraviolet light,...
