The treatment of congenitally developed fused vulva labia in a Brown-Swiss heifer

A case of congenitally developed fused labia in a 13-month-old Brown-Swiss heifer, an uncommon entity, is described. On gross appearance of vulva, it was observed that there were only 2 small openings in the dorsal and ventral vulvar commissures. Ultrasonography of the genital tract revealed the presence of left and right ovaries, uterine horns, and cervix uteri. The abnormality of the vulva was surgically corrected. The heifer was synchronized and artificially inseminated postsurgically. During delivery, no complication was observed and a healthy male calf was born. To the authors' knowledge, this is the first report describing both the surgical treatment of and delivery of a heifer with congenitally developed fused labia in Brown-Swiss cattle.
