Resumo: | The aim of the present study was to evaluate the effects of season of the year (summer and winter) and parity (heifers and cows) on oocyte quality and number in buffaloes. For this purpose, 71 buffaloes had follicular wave emergence synchronized before OPU. OPU of all follicles ≥ 2mm was done 5 days after the beginning of the hormonal protocol, in 4 replicates (two for each season). Data were analyzed by ANOVA using PROC GLIMMIX, in a 2 x 2 factorial arrangement of treatments. No interactions were observed in following variables: number of follicles, number of total and viable oocytes, recovery rate, percentage of viable oocytes, grade I oocytes, grade II oocytes, grade III oocytes, denuded oocytes, expanded cumulus oocytes, and atretic/ degenerated oocytes. Number of follicles visualized at OPU and recovery rate were not affected by parity or season. Relative to parity, number of total and viable oocytes were greater in heifers than in cows, respectively. Concerning season of the year, number of viable oocytes and viable oocyte rate were increased in winter. In conclusion, better oocyte quality can be obtained from heifers and during winter in buffaloes. However, the number of total oocytes seems to be more influenced by parity than by season of the year in this species. |
