Changes in Quality of Native and Frozen-thawed Semen in Relation to Two Collections Performed in a 24-hour Interval and Addition of Clarified Egg Yolk to Extender
Original language description
The aim of the study was to evaluate the effect of repeated semen collection and the substitution of normal egg yolk with clarified egg yolk to commercially produced semen extender on qualitative parameters of frozen-thawed canine semen. Two semen collections were scheduled in a 24-hour interval and in each of six dogs, three 1st and three 2nd collections were performed. The frozen-thawed sperm samples were prepared either with clarified or normal egg yolk and motility and viability were evaluated. The effect of the sequence of semen collection was demonstrated by significant differences in motility and also in viability of sperms both in native and frozen-thawed ejaculate. The percentage of viable sperms was significantly higher in samples from the 2nd compared to the 1st collection. This trend was the same also in motility except in native ejaculate. The addition of clarified egg yolk was beneficial for higher survival of sperms immediately after thawing and also after 30 min of incubation, compare
