将HCl注入绵羊瘤胃导致尿液pH值下降，并导致尿液中重碳酸盐的重吸收。尿液中酸的排泄量上升，直到大约等于进入瘤胃的酸量。尿液中可滴定的酸很少，90%以上的排泄酸以铵离子的形式存在。可滴定酸排泄的限制似乎与观察到绵羊通常在尿液中排泄很少的磷（磷酸盐）有关。
绵羊对酸中毒的肾脏反应不受饮食中钾含量的影响。
Infusion of HCl into the rumen of sheep led to a fall in the pH of the urine and to the reabsorption of bicarbonate from the urine. Excretion of acid in the urine rose until it was about equal to the amount of acid given into the rumen. There was very little titratable acid present in the urine and over 90 per cent of the acid excreted was in the form of ammonium ions. The limitation in the excretion of titratable acid seems to be related to the observation that sheep normally excrete very little phosphorus (as phosphate) in the urine.
The renal response to acidosis in sheep was not influenced by the amount of potassium in the diet.
