Groups	No. of Oocytes Observed	No. of MII Oocytes (%)
IOs	293	174 (59.4 ± 3.14) ^Aa

^a,b^,c Values with different superscripts represent significant difference within the same column (p < 0.05); ^A,B Values with different superscripts represent highly significant difference within the same column (p < 0.01), IOs, the inferior bovine oocytes ; MT, melatonin; COCs, cumulus–oocyte complexes.
