Electroejaculation in goats.
A comparison was made of a sine-wave and a pulse-wave electroejaculator for the collection of semen from male goats. Six animals were ejaculated once, using one or other instrument and 8 were ejaculated with each device with an intervening rest period. Comparing the sine-wave with the pulse-wave equipment, the mean total number of sperm collected was 5.3 x 10(9) and 2.1 x 10(9) cells respectively, in the first experiment and 4.0 x 10(9) and 1.0 x 10(9) cells, respectively, in the second experiment. In the latter experiment, a significant difference (p less than 0.05) was found in the sperm concentration, which was higher with the sine-wave generator. This instrument, with controlled output, was considered less stressful to the animal.
