This study investigates the efficacy of five extenders in contributing to the outcome of semen cryopreservation in Formosan Sika and Sambar deer. Pooled semen ( n=4) of six males of each breed was used. In Sika deer, semen collection rate was 96% (23/24) over all electro-ejaculations. Volume, sperm...
