The freezing ability of semen from Alpine and Saanen goats submitted to an artificial photoperiod exposure were evaluated by the thermo-resistance (TTR) and hypoosmotic (HOST) tests and integrity of the acrosome using eight male goats, four of each breed and two age groups (young and adults). The quality of semen during the freezing process was superior for the young animals of both breeds. Spermatic motility immediately after thawing showed a positive effect on TTR; animals with higher motility after collection […]
