Effect of follicle size on oocytes recovery rate, quality, and in-vitro developmental competence in Bos indicus cows

The objective of the present study was to determine the effect of follicle size on recovery rate, quality, and in-vitro developmental competence of oocytes in Bos indicus cows. The ovaries (n = 507) of Bos indicus cows having age of 5-8 years, with mixed parity, BCS 2.75 ± 0.25, and clinically normal reproductive tracts were collected from the local abattoir. The follicles on the ovaries were divided into two groups based upon their size; 1) ≥6 mm diameter, and 2)
