A preliminary technique for electro-ejaculation of agouti (Dasyprocta leporina)

This study focused on the effectiveness of electro-ejaculation of the agouti (Dasyprocta leporina) and analysis of the collected semen. Sexually mature male agouti were anesthetized with ketamine and electro-ejaculated. The means of ejaculation time was 5.48 ± 0.31 min, ejaculation voltage was 9.33 ± 0.69 V, ejaculation voltage range was 6–12 V, amps was 0.5–1.5 amps, ejaculation volume was 0.47 ± 0.12 ml and pH was 8.3 ± 0.09. Mean spermatozoa concentration, motility and percentage abnormalities were (106.7 ± 31.1) × 106 spermatozoa/ml, 50.44 ± 4.44%, and 35.14 ± 2.76%, respectively. Thirty percent of the semen samples collected contained spermatozoa. The most significant result from these experiments was the inverse relationship between ejaculation time and ejaculate volume, which suggests that the maximum ejaculation time for electro-ejaculation of the agouti should not proceed beyond 6 min. Secondly, the results indicate that the time of the off periods should be shortened to 3–4 s.
