Effects of dilution rate on the motility and acrosome morphology of boar spermatozoa stored at 15 °C

The objective of this investigation was to establish the optimal extent of dilution for storage of boar spermatozoa at 15°C in Kiev diluent. The dilution titers used for the sperm‐rich fraction of ejaculates from 8 boars ranged from 12 to 150. Seminal doses were stored for 10 days. Motility and acrosome morphology were evaluated after 1, 3, 5, 7, and 10 days of storage. The percentages of motile spermatozoa after 24 and 72 hours of storage were significantly higher for dilution rates between 17 and 111 than for dilution rates lower than 17 or higher than 111 (p < 0.05). The percentages of spermatozoa with normal acrosomes after 24, 72, and 120 hours of storage were significantly higher for dilution rates between 18 and 1:11 than for dilution rates lower than 1:8 or higher than 1:11 (p < 0.01).
