Qualidade e Quantidade de Oócitos Caprinos e Ovinos Recuperados por Aspiração e Fatiamento / Quality and Quantity of Goats and Sheep Oocytes Recovered by Bspiration and Slicing

ABSTRACT

This study aimed to compare the aspiration techniques and slicing ovaries in order to obtain oocytes, byassessing the quantity and quality of oocytes recovered from goat and sheep females slaughtered in São Luís -MA. The ovaries were collected after slaughtering and kept in saline solution at 0.9%, containing 30 µg / mL ofgentamicin sulfate. In the laboratory the ovaries were randomly divided into two groups with subsequent processof aspiration and slicing. The average rate of oocyte retrieval by aspiration technique were 4,53 oocytes/ovaryin sheeps and 4,11 oocytes/ovary in goats, and by the slicing technique 5,26 oocytes/ovary in sheeps and 5,06oocytes/ovary in goats. It was not observed a significant difference between the recovery rate between species,however there was statistical difference between the techniques on goats, therefore demonstrating that the twotechniques can be used for oocyte retrieval.(AU)
