Postoperative evaluation of the surgical treatment of accessory teat and gland cistern complexes in dairy cows.

The purpose of this study was the long-term evaluation of a method of surgically repairing the abnormal condition of accessory teat and gland cistern complexes in dairy cattle. A prospective evaluation of three cows that had undergone the procedure was done. These cows were evaluated from four months to one year, postoperatively. A thorough history, physical examination, contrast radiography, and ultrasonic examination were done on each cow. A retrospective evaluation of an additional 13 cows that had also undergone the procedure was obtained four months to three years following the surgery, via owner communication. The prospective portion of this study demonstrated patency of the communication between main and accessory teat cisterns. Postoperative complications included initial slow milking and mild swelling of the involved teat. These problems resolved in all cows one to two months postoperatively. None of the 16 cows that had undergone the surgery either developed or was treated for mastitis. Likewise, none of these cows was sold or slaughtered as a result of postoperative teat problems or unsatisfactory milk production. Our study demonstrated that this particular method of surgical correction of accessory teat and gland cistern complexes is effective, is esthetically acceptable, produces minimal associated complications, and preserves the milk production capacity of the gland.
