bulls, artificial insemination, flow cytometry, fertility, seman quality
Frozen semen samples from Holstein bulls were measured by the sperm chromatin structure assay (SCSA), a new procedure utilizing flow cytometry for the valuation of sperm quality. Fertility ratings of the bulls were known based on their use in artificial insemination matings. Values obtained by the SCSA were highly correlated (r= -.58 P<.01 with bull fertility ratings. Results of this research indicate the SCSA may be a valuable technique for measurement of sperm cell quality and detection of suboptimal fertility in bulls.
