虽然亚急性瘤胃酸中毒（SARA）的确切定义仍有争议，但可以肯定的是，SARA存在于大量奶牛群中，影响有限比例的动物。然而，对兽群中单个动物的确切影响是不确定的。根据目前的知识，我们似乎可以公平地假设，SARA本身并没有对个体和群体产生负面影响，而是与其他病理改变同时发生。未来的挑战是描述SARA对畜群水平的影响。对饲料效率的不利影响似乎是最重要的经济后果。此外，研究可能会集中在SARA是否必须被理解为区分奶牛群中最佳管理和次优管理的信号。(C) 2011 Elsevier B.V.版权所有
Whilst the exact definition of subacute ruminal acidosis (SARA) remains debatable, it is certain that SARA is present in a large number of dairy herds, affecting a limited proportion of animals. It is uncertain, however, what the exact consequences in the individual animal within a herd are. Based on the current knowledge, it appears fair to assume that not SARA in itself has negative consequences in the individual as well as in the herd, but that these are arising simultaneously with other pathologic alterations.The challenge for the future is to describe the impact of SARA on herd level. Detrimental effect on feed efficiency described seems to be the most important economic consequence. Furthermore, research may focus on the question whether SARA has to be understood as a signal differentiating optimal from suboptimal management in dairy herds. (C) 2011 Elsevier B.V.
