Abstract

The goal of this study was to evaluate the effect of the donor and the months of the year on the oocyte recovery rate in Senepol donors. Data on 604 follicular aspirations guided by ultrasound, performed on 33 healthy cows aged between two and seven years were evaluated. Data were made available through individual spreadsheets by a commercial company. All donors belonged to the same batch and breeding farm and were kept under the same food management. Viable and degenerate oocyte recovery rates and the effect of the month of collection and the individual factor of the donor were analyzed. Data were tested by analysis of variance (ANOVA) followed by Tukey’s test, with a significance level of 5%. A significant number of total (27.13 ± 14.38) and viable (23.17 ± 12.94) oocytes was observed. The number of grade I oocytes was high among the donors, and the number of total and grade II and III oocytes were the least altered between the months evaluated. There was an excellent number of oocytes recovered, with variation observed according to the donor and the month of the year evaluated.
