Liver abscess has been identified in multiple classes of cattle, but cattle consuming higher energy diets may have greater prevalence of abscessation. The presence and severity of liver abscess has been associated with reduced dry matter intake, daily gain, and gain efficiency of individually fed animals, and as the prevalence of abscesses within pens of animals increases, growth performance worsens. Because of the importance of the liver to metabolism, damage due to abscess could negatively affect energy utilization. A preliminary analysis indicates severe liver abscess incidence increases the requirement of metabolizable energy for maintenance.
肝脓肿已在多种牛群中被发现，但食用高能量日粮的牛可能有更高的肝脓肿发生率。肝脓肿的存在和严重程度与个体饲养动物的干物质采食量、日增重和增重效率降低有关，而且随着动物围栏内脓肿的发生率增加，生长性能会恶化。由于肝脏对代谢很重要，脓肿造成的损伤可能会对能量利用产生负面影响。初步分析表明，严重肝脓肿的发病率增加了维持所需代谢能的需求。
