Sažetak
The study examined the influence of season on several parameters of fresh semen ejaculates and the post-thawing motility of the sperm of Arabian stallions. Three Arabian stallions were used for semen collection using a Missouri-type artificial vagina. Semen was evaluated macroscopically for volume, colour and consistency, and microscopically for motility, concentration of sperm, and total sperm count in ejaculates. The semen was frozen using di-methyl formamide egg yolk based freezing extender and evaluated for post-thawing motility. Results revealed that the volume of semen, total number of sperm per ejaculate and the post-thawing motility in the breeding season was significantly higher than in the non-breeding season, while the opposite was true for sperm cell concentration. There was no difference in colour, consistency or motility between stallions in either the breeding or non-breeding season. In conclusion, season had a direct influence on semen volume, sperm cell concentration, total number of sperm, and post-thawing motility of sperm of Arabian stallions.
