Effect of Equine Chorionic Gonadotropin on Follicular and Luteal Vascularisation and Progesterone Production in Murrah Buffaloes Subjected to Ovulation Synchronisation.

This study evaluated the effect of equine chorionic gonadotropin (eCG) on ovarian vascularisation and plasma progesterone (P4) levels in Murrah buffaloes during an ovulation synchronisation protocol. Twenty buffaloes were divided into two groups: with eCG (n = 20) and without eCG (control, n = 20) in a crossover design. A 1.
