During all of 1974, we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle maintained at 1,600 m altitude. Of 1,988 cattle necropsied, 116 (5.8%) had brisket disease. The malady occurred during all seasons but was most common throughout fall and winter. The gross changes were hypertrophy and dilatation of the right ventricle and generalizaed passive congestion. The postulated causative factors were high genetic susceptibility, rapid growth rate, previous mountain grazing, and hypoventilation with airway hypoxia.
在1974年全年，我们对海拔1600米处饲养的约40.7万头一岁育肥牛的疾病和死亡情况进行了调查。在1988头接受尸检的牛中，116头（5.8%）患有胸病。这种疾病在所有季节都有发生，但在秋冬季节最为常见。大体变化为右心室肥大和扩张以及全身性被动性充血。推测的致病因素包括高遗传易感性、快速生长率、先前的山地放牧以及伴有气道缺氧的通气不足。
