Abstract

Fat cow syndrome (fatty liver disease) is a common metabolic problem in dairy cow production during the transition period, from the dry period to lactation. This syndrome occurs when due to liver uptake of non-esterified fatty acids (NEFAs), they are stored in excess as triacylglycerols (TAGs) in the liver. Currently, diagnosis of this disorder must be confirmed by a liver biopsy to determine the fat content of liver cells, as well as blood tests for increased levels of liver enzymes (GGT, SDH, AST, and bilirubin). Fat cow syndrome is associated with the occurrence of clinical diseases, decreased immunity, and problems with reproduction. It is a major problem in the herd health due to the high cost of veterinary services, a longer calving interval, and reduced longevity of cows, causing enormous economic losses. The best means of prevention is good nutrition and routine blood tests in the herd.

奶牛脂肪肝病的危险因素、症状及预防
肥牛综合征(脂肪性肝病)是奶牛生产从干期到哺乳期过渡时期常见的代谢问题。当肝脏摄取非酯化脂肪酸(NEFAs)时,它们以三酰基甘油(TAGs)的形式过量储存在肝脏中,就会发生这种综合征。目前,这种疾病的诊断必须通过肝活检来确定肝细胞的脂肪含量,以及血液检测肝酶(GGT、SDH、AST和胆红素)水平的升高来证实。肥牛综合征与临床疾病的发生、免疫力下降和生殖问题有关。由于兽医服务费用高,产犊间隔时间长,奶牛寿命缩短,造成巨大的经济损失,这是畜群健康的一个主要问题。最好的预防方法是在牛群中进行良好的营养和常规血液检查。
