COMPARATIVE EFFICACY OF ASPIRATION AND DISSECTION TECHNIQUES ON THE RECOVERY OF OOCYTES FROM GOAT OVARIES

Abstract

A total of 200 goat ovaries with intact reproductive tract were collected immediately after slaughter in a thermoflask containing warm (35° C) physiological saline. The ovaries of different animals were assigned to aspiration and dissection techniques for recovery of oocytes alternately. In aspiration and dissection techniques the number of oocytes recovered per ovary was 2.01 and 2.23 respectively and the rate of recovery was 76. 72 and 85.11 per cent respectively, the difference being significant (p < 0.05). The recovery of oocytes of A, B, C and D categories was 39.69, 9.16, 10.69 and 17.18 per cent respectively for aspiration technique and 54.58. 16.03, 8.02 and 6.49 per cent respectively for dissection technique. The recovery of oocytes of A category and A + B categories was significantly (p < 0.05) higher in dissection technique.
