【 摘 要 】

Problem statement: Males rather than females of the White-Tailed deer (Odocoileusvirginianus texanus) are more susceptible to hunting because their physical characteristics, thereforetheir elimination can increase a genetic degradation and a lower productivity because of the effect ofgender. Thus, the aim of the current study was to evaluate the effect of age and postmortem time ofWhite-Tailed deer on its epididymal-tail sperm motility and morphology and the response to spermcryopreservation. Approach: Twenty two hunted deer were used and were classified into three agegroups:A = 1.5-3.5; B = 4.5-5.5 and C = 6.5-7.5 years old and four groups according to postmortemtime: 1= 0-3; 2 = >3-5; 3 = >5-7 and 4 = > 7 h. Two samples per animal (one per each epididymal)were diluted and frozen with Triladyl
