Successful management of mid cycle estrus in Murrah buffaloes- A prelimnary case study

Two pleuriparous Murrah buffaloes were presented with the history of artificial insemination 9 days back and since early morning animal exhibiting signs of estrus. Per rectal and ultrasonographical examination revealed presence of dominant follicle and CL on different or same ovary at the same time, uterus was toned and oedematous with scanty thick cervico vaginal discharge on back retching. To study the hormonal milieu serum progesterone estimation was done in both mid cycle estrus buffaloes and in other two animals with normal estrous cycle in same stage (Day 9 from the last date of A.I.). The diameter of CL was larger in buffaloes exhibiting midcycle estrus than that of true estrus. In this case study, during mid-cycle estrus secretion of estrogen was higher from dominant follicle of first follicular wave and due lower progesterone concentration from insufficient CL animal exhibit signs of estrum in mid lutel phase.
