in fresh samples and in samples equilibrated with the
cryoprotectant; in contrast, the same correlation was found
in thawed semen. Before freezing, different proportions of
viable and motile sperm were measured in the same
sample, and this difference might account for the absence
of correlation between the two quality parameters. A
similar lack of correlation between the proportion of viable
and motile sperm was previously reported for both fresh
and cryopreserved chicken semen
