1 GOAT SEMEN COLLECTION AND PROCESSING BY DR. LOUIS ...

predictive of sperm fertility. However, these systems have evolved to the point where reliable,
accurate data systems have evolved to the point where reliable, accurate data on cell counts,
concentrations, number of motile cells, % motility, mean linearity, straight line velocity, curvilinear
velocity, and lateral head displacement can be generated (Fig. 5). Also, some systems are able to
track and plot individual sperm cells for several seconds (Fig. 6). It is now possible to determine the
effects of processing treatments on these parameters. Coupling this "high technology" assessment
of semen quality, with a bioassay assessing fertility, would greatly strengthen the assessment of a
buck's reproductive value. Such a bioassay may be the use of the zona-free hamster ova penetration
test developed by Yanagimachii in 1976. He found that capacitated human sperm cells were capable
of penetrating hamster vitellin (zona-free ova) by removing the zona pellucidae and that the fertility
of the male was correlated with the level of penetration.
