AB  - Problem statement: Males rather than females of the White-Tailed deer (Odocoileus
virginianus texanus) are more susceptible to hunting because their physical characteristics, therefore
their elimination can increase a genetic degradation and a lower productivity because of the effect of
gender. Thus, the aim of the current study was to evaluate the effect of age and postmortem time of
White-Tailed deer on its epididymal-tail sperm motility and morphology and the response to sperm
cryopreservation. Approach: Twenty two hunted deer were used and were classified into three age-groups:
A = 1.5-3.5; B = 4.5-5.5 and C = 6.5-7.5 years old and four groups according to postmortem
time: 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® and Tris-Fructose. Thawing was done 72 h post freezing. Results: Age did not neither affect motility nor morphology (p>0.05). Postmortem time had a deleterious effect on motility (p
