胃肠道脂多糖对奶牛健康及生产性能的 影响及其防治措施
Effects of Gastrointestinal Endotoxin on Health and Production Performance of Dairy Cows and Prevention Methods
摘要
Abstract
Endotoxin is a composition of cell outer membrane of Gram negative bacteria, feeding high-concen-trate or low-neutral detergent fibre diets can result in a remarkably increased content of gastrointestinal endotox-in. Gastrointestinal environmental factor such as endotoxin and pH can cooperate to damage epithelial cells, then endotoxin will translocate from the gastrointestinal tract into peripheral circulation which will cause a series of immune metabolic changes, and affect the health and production performance of cows. This article reviewed structure and source of endotoxin, effects of gastrointestinal endotoxin on health and production performance of dairy cows and the prevention methods, in purpose to provide references for ensure health and enhance produc-tion performance of cows.关键词
