Abstract

®V10 software. South African indigenous goats had total sperm cell motility rate of 83.1%, progressive sperm cell motility of 49.3% and non-progressive sperm cell motility of 33.9%. Moreover, acidic semen pH of 6.4 and low sperm cell concentration (663.6 × 10 6 /ml) were obtained. Removal of seminal plasma and semen cryopreservation significantly decreased pH (5.8 ± 0.1 and 5.7 ± 0.1 for frozen-thawed washed and not-washed, respectively) and sperm cell motility rates of South African indigenous goats. Reduction in the sperm cell motility after freeze/thawing is still a problem and requires further research on the diluents and techniques that give protection to sperm cells during cryopreservation.
