Resumo

Which was used sixteen samples of adult goats semen collected using an artificial vagina weresubjected to cryopreservation in order to verify the influence of equilibration time at a temperature of 5 °C onthe freezability of goat semen. Were distributed in the different protocols equilibrium time: 1h equilibration time(G1); 2 h equilibration time (G2); 3h equilibration time (G3).After this process the samples were placed inliquid nitrogen vapor , and maintained for 20 min . The end was made the freezing process in cryogenics tank .Thawing was performed in a water bath at 37°C for 30 seconds. The averages for motility were 19.375 %,16.875 % and 16.250 % respectively for G1, G2 and G3. This study demonstrated effect of equilibration period ,on the viability of goat semen after the process of freeze-thaw, where the group of smaller G1 exposure time wasless deleterious effects.(AU)
