ASPIRAÇÃO FOLICULAR VIDEOLAPAROSCÓPICA COMPARATIVA EM OVELHAS DORPER E SANTA INÊS

This study aimed to compare the number of aspirated follicles, recovered oocytes, oocyte quality and viability between Dorper and Santa Ines ewes submitted to the videolaparoscopic ovum pick-up. To conduct this study, 118 follicular aspirations were performed, of which 65 were performed in Dorper ewes and 53 in Santa Ines ewes. The results for Dorper sheep were 28.31 ± 17.42 follicles/ewe, 12.21 ± 6.74 oocytes/ewe, recovery rate of 47.9% and 8.93 ± 5.25 viable oocytes/ewe. For Santa Ines ewes the results were 22.14 ± 16.08 follicles/ewe, 12.64 ± 8.29 oocytes/ewe, recovery rate of 55% and 8.92 ± 6.58 viable oocytes/ewe. There was no influence of breed on the number of aspirated follicles, recovered oocytes, recovery rate, oocyte quality and viability in videolaparoscopic ovum pick-up.
