A compilation of semen collection
data produced at La Raya research station is shown in
Table 1. Nearly, 92% of ejaculates collected are suitable for
preservation and artificial insemination, i.e., spermatozoa
concentration greater than 80 million spermatozoa/mL,
90% live spermatozoa, and 80% motile spermatozoa. However,
factors such as size of the herd and numbers of males
available for a reliable semen sample must be considered
in the success of the technique.
