Resumo

The animals were divided into three groups G1, G2, G3. Semen collected was diluted in Tris-yolk baseand packaged in 0.25 ml straws, a dose of 100 x 106 sperm. Semen samples were distributed in differentequilibrium time protocols. The group 1 (1h), group 2 (2 h), group 3 (3 h). Mean values for motility were19.37%, 16.87% and 16.25% respectively for G1, G2 and G3. To analyze (TTR) which consisted of placing asemen , and incubated at 37°C for a period of 120 minutes. The force sperm motility and sperm were evaluatedby TTR in different time: 0, 60, 120, 180 minutes. The indices obtained from motility and sperm vigor wereevaluated by PROC GLM (SAS, 2001) and proceeded to the 5% Tukey test. This study demonstrated effect theequilibration period, on the viability of goat semen after the freeze-thaw process, in which the semen exposed toless cooling time has a higher sperm viability.(AU)
