Two late gestation Holstein cows about to begin the third lactation developed massive vulvar edema. These were the only affected animals in the herd of 500 milking cows. The vulvar edema spontaneously regressed postpartum for both cows. Massive vulvar swelling is seldom observed in dairy cows in advanced pregnancy and is not described in the literature.
两头即将开始第三次泌乳的妊娠后期荷斯坦奶牛出现了大面积的外阴水肿。在这500头奶牛的牛群中，这是仅有的受影响动物。两头奶牛的外阴水肿在产后均自行消退。在妊娠后期的奶牛中很少观察到大面积的外阴肿胀，文献中也未对此进行描述。
