Effect of corpus luteum: quality and recovery rate of buffalo (Bubalus bubalis) oocytes

Recovery rate and quality of oocytes were investigated from abattoir collected ovaries with and without corpora lutea (CL). The oocytes were categorized into four grades: grade-A, grade-B, grade-C, and grade-D based on the presence of the cumulus cells complex around the oocytes. The number of oocytes per ovary were 1.7 ±0.1 and 1.5 ±0.1, obtained from ovaries without CL and with CL, respectively. Recovery rate of different grades of oocytes from ovaries with CL and without CL were almost identical.
