Coleta e avaliação do sêmen de catetos (Tayassu tajacu)

Abstract

The aim of this research was to test two electroejaculation protocols and to study the motility, vigor, concentration and morphologic alterations in captive collared peccaries semen. Six males with age between 10 and 18 years had used. The animals were anesthetized with zolazepan cloridrate and tiletamine cloridrate and the semen collected by electroejaculation. Average semen volume was 3,11 + 0,9mL, motility was 48.7 ± 31.5%, vigor, 2.1 + 1.4 and concentration, 87.0 + 53.1 x 10(6) sptz/mL. It was concluded with this research that three sessions of 15 stimulations/12 volts was considered efficient for collared peccaries semen collection and that morphological spermatic results were compatible with testicular degeneration.
