Abstract: Research development in semen collection and sperm evaluation of Tayassu tajacu are necessary. The aims of this research were to evaluate testicular biometry of captive collared peccaries, test electroejaculation for semen collection and evaluate seminal characteristics during the year. Eight animals were submitted to electroejaculation and semen samples were evaluated according their physical and morphological characteristics. Left testicles measured 3.8 ± 0.4 cm X 2.6 ± 0.3 cm and presented 2.3 ± 0.2 of consistence, while right testicles were 3.8 ± 0.5 cm X 2.7 ± 0.3 cm and presented 2.3 ± 0.2 of consistence. Success rate on semen collections achieved 75.21%. Semen presented 0.81 ± 0.86 mL (volume), 137.44 ± 153 x 106 sptz mL-1 (sperm concentration), 7.92 ± 0.73 (pH), 52.66 ± 28.79% (sperm motility), 2.2 ± 0.8 (vigour), 55.84 ± 28.55% (plasmatic membrane integrity), 22.87 ± 12.93% (primary defects), 9.11 ± 5.88% (secondary defects) and 31.52 ± 13.81% (overall defects). Seminal characteristics showed no expressive variation along the year. Testicular symmetry was observed, electroejaculation was an efficient method to semen collection and slight mensal oscillations of seminal quality were not enough to characterize collared peccaries as seasonal reproductive animals.
