Mortality from digestive diseases in feedlot cattle is second only to that from respiratory diseases. Acidosis is a major digestive disorder and is likely to continue because of ongoing attempts to improve the efficiency of beef production by feeding more grain and less roughage. Subacute acidosis is the most prevalent form of acidosis in feedlots but is difficult to diagnose because of the absence of overt clinical signs. Control of acidosis is achieved largely by sound nutritional management. No single strategy or solution exists; however, an effective management strategy should factor in dietary formulation, a consistent feeding program, prudent bunk management, use of nonstarch by-products, and feed additives to minimize pen-to-pen and animal-to-animal variations in feed intake.
饲养场肉牛消化系统疾病导致的死亡率仅次于呼吸系统疾病。酸中毒是一种主要的消化系统紊乱疾病,由于目前仍在尝试通过增加谷物喂食量和减少粗饲料量来提高牛肉生产效率,酸中毒很可能会持续存在。亚急性酸中毒是饲养场中最普遍的酸中毒形式,但由于缺乏明显的临床症状,很难诊断。酸中毒的控制主要通过合理的营养管理来实现。不存在单一的策略或解决方案;然而,有效的管理策略应考虑日粮配方、一致的饲喂计划、谨慎的饲槽管理、使用非淀粉类副产品以及饲料添加剂,以尽量减少栏间和动物间采食量的差异。
