Beef cattle are less prone to metabolic diseases as compared with dairy cattle; however, there are disease entities of concern in feedlot and cow-calf beef cattle operations. In one study, a prevalence of 2% was found for ruminant acidosis in a feedlot; however, there is little prevalence information published with regard to metabolic diseases in beef cattle.1 Metabolic diseases covered in this article are hypomagnesemia, ruminal acidosis, and all of the common sequelae, polioencephalomalacia, manganese deficiency, and protein-energy malnutrition (PEM).
与奶牛相比，肉牛较少患代谢疾病；然而，在育肥场和奶牛-小牛肉牛养殖场中，仍存在一些令人关注的疾病实体。在一项研究中，育肥场反刍动物酸中毒的患病率为 2%；然而，关于肉牛代谢疾病的流行情况信息很少有发表。本文涵盖的代谢疾病有低镁血症、瘤胃酸中毒以及所有常见的后遗症，如脑软化症、锰缺乏症和蛋白质能量营养不良（PEM）。
