Overdue Holstein Fetus - 7.5 Months.
This 7.5 month old fetus failed to initiate parturition presumably due to a defective pituitary gland. It was delivered alive after induction with 30 mg dexamethasone 91 days after the projected due date. The cervix was fully dilated 3 days later and delivery was by manual extraction. The calf died after several spontaneous breaths. There was a lack of mammary development at the time of delivery. Normal lactation developed later in the 6 year old dam.
