Effects of two maturation media (TCM-199 and Ham's F-12) with and without the addition of oestrus buffalo serum (OBS) and hormones (FSH, LH, E2) on the maturation rate of buffalo follicular oocytes were evaluated. The results revealed a significant (P < 0.05) increase in the maturation rate when the OBS and hormones were added to TCM-199 than in Ham's F-12 medium. The percentage of maturation rates in TCM-199 + hormones + OBS, TCM-199 + hormones, TCM-199 + OBS and TCM-199 were 77.44, 55.17, 62.28 and 26.62 percent, respectively. While in Ham's F-12 + OBS + hormone, Ham'F-12 + hormone, Ham's F-12 + OBS and Ham's F-12 were 32.85, 27.52, 31.38 and 13.46 percent, respectively. A significantly higher (P < 0.05) fertilization rate was recorded for modified Ca2+ free Tyrode's medium (63.72%) than in TALP (10.9%) and IVF-TL (32.18%). Thus, TCM-199 containing hormones and OBS appeared better for in vitro maturation, whereas modified Ca2+ free tyrode's medium was found to be more suitable for in vitro fertilization of buffalo follicular oocytes.
