Colheita de sêmen por eletroejaculaÇão em cutia-parda (Dasyprocta azarae)

Abstract

Agoutis are animals that live in South and Central America, present rearing potential and call increasing scientific interest. The aim of this paper was to establish a model for semen collection by electroejaculation in Azarás agouti (Dasyprocta azarae). Anesthetized adult males (n=4) were submitted to four series of 20 electroejaculatory stimuli, during 3 seconds each and with 2, 4, 6 and 8 volts, with a 2 minutes rest among series. Semen collection was accomplished in every animal, with partial penis erection at 2 volts, makeable erection at 4 volts, ejaculation at 6 volts, glans and penis spines exposition at 8 volts, and sperm collected in all samples. The described technique for Azara's agouti semen collection was efficient.
