Stallion Sperm Viability, as Measured by the Nucleocounter SP-100, Is Affected by Extender and Enhanced by Single Layer Centrifugation

Figure 5

Effect of Single Layer Centrifugation through Androcoll™-E on mean stallion sperm viability $(n=45)$. Note: a:difference in sperm viability at 0 and 24 hours was statistically significant for the uncentrifuged samples in both extenders; b: SLC-samples in INRA96 had a higher viability than non-SLC samples at 0 hour $(P<.001)$; c: difference between uncentrifuged and SLC-samples in Kenney’s extender at 0 hour, $P<.02$; d: SLC samples in both extenders had a higher viability than the uncentrifuged samples at 24 hours $(P<.001)$.
