Summary

Semen from four Holstein bulls was evaluated to compare effects of four extender treatments on post-thaw semen quality. The extender treatments were as follows: 1) milk and milk; 2) milk and egg yolk-citrate; 3) egg yolk-citrate and milk; and 4) egg yolk-citrate and egg yolk-citrate. Semen was evaluated at thawing and after 30, 60, 120, and 180 minutes of incubation at 38.5 deg C. Post-thaw motility scores tended to be reduced for 4). Results demonstrate differential extender effects on post-thaw semen quality and indicate that altering extender composition or sequence of adding extender components may improve post-thaw quality of cryopreserved sperm.
