In healthy sheep the reaction of the urine has generally been accepted to be on the alkaline side ( 1963). Thus (1928) only found 2 of 40 healthy sheep with an acid urine. reported that nursing animals in contrast to adults will produce an acid urine. However, the influence of feeding on urine pH and plasma bicarbonate levels in sheep does not seem to have been systematically investigated. During recent years it has often been observed in this laboratory that healthy animals, examined as a matter of routine, may produce an acid urine. Based on these observations healthy sheep under different feeding conditions were examined in order to elucidate the influence of the diet on the pH of the urine and the plasma bicarbonate content. Since an excessive lactic acid production and increased fat metabolism may also influence the acid-base balance, the lactic acid concentration of rumen fluid was determined, and the urine was tested for ketone bodies.
在健康绵羊中，尿液反应一般被认为呈碱性（1963年）。因此，（1928年）在40只健康绵羊中仅发现2只尿液呈酸性。报道称，与成年动物相比，哺乳期动物会产生酸性尿液。然而，饲料对绵羊尿液pH值和血浆碳酸氢盐水平的影响似乎尚未得到系统研究。近年来，本实验室经常观察到，作为常规检查对象的健康动物可能会产生酸性尿液。基于这些观察结果，对不同饲养条件下的健康绵羊进行了检查，以阐明日粮对尿液pH值和血浆碳酸氢盐含量的影响。由于乳酸产生过多和脂肪代谢增加也可能影响酸碱平衡，因此测定了瘤胃液中的乳酸浓度，并对尿液进行了酮体检测。
