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) less then 6 mm diameter. After initial evaluation of quality of the oocytes, the COCs were in vitro matured, fertilized, and cultured to determine the in vitro developmental competence. The oocyte recovery, quality, maturation, cleavage, 4-cell, 8-cell, and 16-cell stages were analyzed using PROC GLIMMIX procedure of SAS. However, the number of oocytes recovered per ovary was analyzed using MIXED procedure of SAS. Results revealed that the recovery of oocytes (LSM ± SEM) derived from the follicles having size less then 6 mm per ovary was greater (1.02 vs. 3.14 ± 0.13; P less then 0. 0001). However, the percentage (n/n) recovery [69.8 (474/679) vs. 62.7% (1454/2320); P = 0.01] and grade I_+_II oocytes [68.4 (324/474) vs. 57.9% (842/1454); P less then 0.0001] was greater in ≥6 mm as compared with less then 6 mm group, respectively. However, maturation rate did not differ [92.9 (288/310) vs. 92.2% (296/321); P = 0.98] between the groups. In contrast, cleavage rate [58.1 (180/310) vs. 47.4% (152/321); P = 0.01], the 4-cell [34.5 (107/310) vs. 18.7% (60/321); P = 0.0003], 8-cell [15.5 (48/310) vs. 7.8% (25/321); P = 0.008], and 16-cell [8.7 (27/310) vs. 2.1% (7/321); P = 0.004] stage embryos were greater in ≥6 mm group. It can be concluded that oocytes der
