Abstract

Assessments of routine ejaculated samples were used to evaluate the conventional semen variables (sperm motility, semen volume, sperm concentration) as initial decision-making criteria to freeze or not to freeze. However, the association of these attributes to the cryotolerance of ram sperm has not been adequately studied yet. The aim of this study was therefore to analyse if the semen volume, sperm motility and concentration can be used to predict post-thaw ram sperm motility. Additionally, in the present study we tested if the order of ejaculate sampling (first versus second, within a single collection session) and the breed of rams influenced cryopreservation outcomes.
