Abstract
A rare case of non-dominant follicular cyst and its reduction by manual
transvaginal follicular aspiration is reported. A Jersey crossbred cow (2 calvings)
was brought to the Teaching Veterinary Clinical Complex, Veterinary College
and Research Institute, Orathanadu with the history of oestrus signs. Trans-
rectal gynaeco-clinical examination revealed a dominant follicle (DF) in the
left ovary and a large follicular cyst like structure (FC: 22.5 mm) in the right
ovary. Ovsynch protocol was initiated on the same day with GnRH (Day 0).
On Day 7, the DF had responded with formation of CL, but the FC found to
be non-responsive and persisting. Prostaglandin was administered and animal
was inseminated on induced oestrus. Animal returned to oestrus within 20
days. Ultrasonographic examination revealed a DF and persistence of F C with
increased diameter (39.9 mm). It was diagnosed as a non-responsive “Non-
dominant follicular cyst”. Under epidural anaesthesia, right ovary was held
trans-rectally and positioned adjacent to the fornix region focusing the F C with
the aid of ultrasound trans-rectal probe. A sterile 21G hypodermic needle was
concealed in the palm of right hand and guided trans-vaginally to pierce the F C
through the ovarian tissue. The evacuation of sero-sanguineous exudate from
FC could be appreciated by the collapse of the structure. Vaginal douche and
antibiotic coverage was carried out for three days.
