The replacement of fresh egg yolk by lyophilized egg yolk in Tris-base extender in cryopreserved Boer and Saanen semen.

Egg yolk is a common cryoprotectant that can be used as a semen extender to protect the spermatozoa from damage during cryopreservation. Therefore, the aim of this study was to investigate the efficacy of fresh and lyophilized egg yolk, as a Tris-base extender, on the quality of cryopreserved goat semen. Semen from 10 rams of two different breeds (Boer and Saanen) was collected using an artificial vagina.
