Abstract
On the assumption that animals of wild feline species died in the field, caudal epididymal sperm were cryopreserved following storage of the feline epididymides at 20°C for 0-24 hr, and their qualities were observed. Compared to the qualities at 0 hr, no significant differences were noted following 12 hr of storage at 20°C. On comparison of the qualities between caudal sperm cryopreserved after 24 hr storage at 4°C and after 12 hr at 20°C followed by 12 hr storage at 4°C, no significant differences were noted. These findings suggest that the cryopreserved sperm collected from epididymides of dead animals might be useful for artificial insemination if cryopreservation was performed within 12 hr exposure to ambient temperature.
