Hepatic lipidosis (ie, fatty liver) occurs primarily during the first weeks of lactation in dairy cows because of excessive lipolysis overwhelming the concomitant capacity for beta-oxidation and hepatic export of triglycerides. Besides economic losses due to reduced lactational and reproductive performance, close associations with concomitantly occurring infectious and metabolic health disorders, in particular ketosis, exist. Hepatic lipidosis is not only a consequence from the postpartal negative energy balance but also acts as a disease component for further health disorders.
肝脂肪病（即脂肪肝）主要发生在奶牛泌乳的最初几周，因为脂肪分解过度，超过了同时进行的β氧化和甘油三酯向肝脏输出的能力。除了因泌乳和繁殖性能下降而导致的经济损失外，还与同时发生的传染性和代谢健康疾病，特别是酮病密切相关。肝脂肪病不仅是产后负能平衡的结果，而且也是进一步发生健康疾病的一个组成部分。
