在荷兰弗里斯兰省18个牛群的197头奶牛中测定了亚急性瘤胃酸中毒（SARA）的患病率。通过瘤胃穿刺术从每个农场的5 - 19头动物中采集瘤胃液样品，并测定每份样品的pH值。对139头奶牛的身体状况在产犊前约3周和产犊后3周进行评分。SARA的总体患病率为13.8%，个别农场的患病率在0%（7个农场）和38%（1个农场）之间。泌乳阶段不影响SARA的患病率，但患有SARA的奶牛在产犊期间失去了更多的身体状况。
The prevalence of subacute ruminal acidosis (SARA) was determined in 197 dairy cows in 18 herds in the Dutch province of Friesland. Samples of rumen fluid were taken by rumenocentesis from between five and 19 animals on each farm and the pH of each sample was determined. The body condition of 139 of the cows was scored approximately three weeks before they calved and three weeks after they calved. The overall prevalence of SARA was 13.8 per cent, and the prevalence on individual farms ranged between 0 per cent (on seven of the farms) and 38 per cent (on one farm). The stage of lactation did not influence the prevalence of SARA but the cows with the condition lost more body condition over the calving period.
