Biometria testicular, eletroejaculação e características seminais de caititus, Tayassu tajacu Linnaeus, 1758 (Mammalia, Artiodactyla, Tayassuidae) mantidos em cativeiro na Amazônia Oriental

Abstract: Estudos relacionados à obtenção e avaliação de sêmen de Tayassu tajacu são escassos, sendo necessárias pesquisas a respeito. Os objetivos do estudo foram avaliar a biometria testicular de caititus adultos cativos, testar a eficiência da eletroejaculação para obtenção de sêmen e avaliar suas características seminais ao longo do ano. Procedeu-se à eletroejaculação em oito animais adultos e as amostras de sêmen colhidas foram avaliadas quanto às características físicas e morfológicas. Os animais tinham testículo … Show more

“…The current findings are consistent to the normal range of sperm morphology accepted for other species, since that 80% normal sperm were verified in the use of all the staining techniques in collared peccaries. However, the values are higher than the 40 (Hellgreen et al 1989) and 68% (Kahwage et al 2010) previously reported for the same species. It is necessary to emphasize that both previous studies collected semen from males that were bred in group together to females.…”

“…After collection, three semen smears were prepared for each ejaculate by using different staining techniques, and 200 cells were counted through light microscopy (1000x) in five randomly selected fields for each smear. The first smear was stained with Bengal rose (Cromato ® , SP, Brazil -Castelo et al 2010); the second smear was stained with brome-phenol blue (Cromoline ® , SP, Brazil - Toniolli et al 2010); and the last one was prepared with eosin-nigrosin stain (Sigma-Aldrich®, SP, Brazil - Kahwage et al 2010). Percentages of normal and altered sperm were verified for each smear, and the percentage of acrosome integrity was also analyzed.…”

“…De acordo com as relações apresentadas entre os métodos, poder-se-ia inferir que a espectrofotometria promove uma superestimação da CE em catetos. De fato, MURGAS et al (2010) já haviam alertado que, apesar dos métodos baseados em densidade óptica, como a espectrofotometria, serem julgados mais objetivos e efi cientes, devese considerar a superestimação dos dados, a qual pode propiciar número menor que o ideal de espermatozoides necessários à fertilização em doses inseminantes, além de induzir a adição excessiva de diluentes (LU et al, 2007).…”
