Description Domestic buffaloes exhibit distinctive breeding patterns that are influenced by seasonal variations. The hot and humid summer season influence reproductive performance affecting by modulating corpus luteum (CL) dynamics and functionality. The present study describes the changes in CL dynamics and serum progesterone (P4) profiling during the breeding (October to February) and non-breeding seasons (April to August) in the Murrah buffaloes (n=6/group). The CL morphometry was recorded using trans-rectal B-mode ultrasonography and blood samples were collected every day for serum P4 estimation using commercial ELISA kit. There was no significant difference observed in CL diameter although the growth and regression rates were higher during the breeding season and luteal regression started earlier in the non-breeding season. The peak P4 concentration was notably higher during the breeding season as compared to the non-breeding season. Additionally, a strong positive correlation between CL diameter and P4 concentration was evident during the breeding season in contrast to the non-breeding season. From this study, it can be concluded that sub-optimal luteal development and function during the non-breeding season could be the key contributing factor associated with poor reproductive performance in buffaloes.
