ABSTRACT
Background: An eight-year-old Ongole cow was brought to the large Gynaecology ward, Department of VGO, NTR College of Veterinary Science, Gannavaram with a history of irregular cloudy vaginal discharge. The local veterinarian did not appreciate the growth of the gravid uterine horn during repeated per-rectal examinations in 30-day intervals. Methods: On rectal examination, the right uterine horn was distended with fluid. On real-time ultrasonography, the ovaries were diagnosed with the presence of large anechoic follicles on both left and right ovaries. The cow was diagnosed as mucometra due to follicular cyst and treated with ovsynch plus CIDR protocol using 20礸 of GnRH and cloprostenol sodium of 500 礸 and CIDR device containing progesterone of 1.9 gms. Results: Re-examination after one month revealed the persistence of cysts on both the ovaries and the distended right uterine horn. Conclusion: The treatment was not successful because of the longstanding follicular cysts and thickening, and unresponsiveness of uterine endometrium. The prognosis of the present case was guarded.
