Ultrasonographic investigation of a repeat breeding cow revealed large anaechoic cyst like structure (22.5 mm) in right ovary and dominant follicle (DF: 12.0 mm) in left ovary. A modified Ovsynch protocol was followed by initiating the treatment with administration of human chorionic gonadotrophin. Persistence and drastic increase in size of cystic structure (38.4mm) was observed, eventhough the DF found to be responded with formation of corpus luteum. Since the cyst didn't respond for hormonal treatments, it was classified as non-responsive and non-dominant follicular cyst (NDFC). A novel trans-vaginal approach of ultrasound guided follicular evacuation of cyst was performed under epidural anaesthesia. The animal returned to cycle normally and there was no recurrence of cystic follicle. The procedure ensures safe collapsing of the cysts without development of adhesions ensured.
