Comparison of sperm-rich fractions of boar semen collected by electroejaculation and the gloved-hand technique.

Semen was collected from 8 yearling boars, using electroejaculation and the gloved-hand technique. Four semen samples were collected from each boar by each technique, on an alternating schedule, with a 72-hour interval between collections. Comparison of the volume, motility, live-dead ratio, sperm concentration, and spermatozoal conformation of the sperm-rich fractions showed that there were no significant differences between the 2 techniques for any factor evaluated.
