La calidad del semen de carneros de la cruza Permer x West African Dwarf
Semen was collected from Permer x West African Dwarf (Permer x WAD) rams for six weeks in dry season (December/January) and for another six weeks in rainy season (May/June). In each season, semen was evaluated for volume, percentage progressive motility, percentage abnormal sperm cells, percentage live sperm and sperm cell concentration. The week in which semen was collected affected total sperm abnormality and percentage live sperm during dry season only. Semen volume, percentage progressive motility and sperm concentration in dry season did not differ from those of rainy season. Total percentage normal sperm cell in dry season was about 70 as opposed to 90 in the rainy season. Percentage live sperm though fairly high in dry seasonwas lower than the corresponding value in rainy season.
