abstract
The study was conducted to understand the physical and palpable changes of female genitalia during the reproductive cycle in 30 apparently healthy, non- pregnant female Manipuri Ponies. The physical and palpable changes of vulva, vagina, cervix, uterus and ovary were recorded during the different days of reproductive cycle. The results showed congestion of vulva on day 0 and day 4 as 100% and 96.66%, respectively. Open cervix were detected in 96.66% on day 0 and 100% on day 4 in oestrus female Manipuri ponies. On the other hand, closed cervix was detected on day 8 to day 18 as 100% during the oestrous cycle. Vaginal discharge was observed on day 0 and day 4 as 16.66% and 40.00%, respectively during the oestrous cycle. 66.66 percent of oestrus Manipuri pony mares showed good uterine tone on day 0 and day 4; whereas atonic uterus was found on day 8 (20%), on day 14 (93.33%) and on day 18 (96.66%) of oestrous cycle. On day 0 and day 4 (100%) oestrus female Manipuri ponies were detected with Graafian follicle, corpus haemorrhagicum was detected on day 8 in 83.33% and mature corpus luteum on day 14 in 100% female Manipuri pony during oestrous cycle.
