摘要 进行了一项研究，以确定来航雏鸡日粮中阴离子、氯离子、硫酸盐和磷酸一氢盐 (HPO4−2) 的日粮补充剂的相对酸原性。氯化物补充剂的范围为 40 至 240 meq/kg，硫酸盐的范围为 100 至 240 meq/kg，磷酸一氢盐的范围为 120 至 240 meq/kg 饮食。在7至10日龄时，阴离子以电荷当量的形式取代膳食碳酸盐（CO3-2），并在实验第一天和实验数天（通常是8天）后采集血样测量血液氢离子浓度、二氧化碳张力和碳酸氢盐浓度（计算）。阴离子对酸碱平衡的影响在第一天就很明显，并且通常在实验期间持续存在。氯化物持续降低血液 pH 值和血液碳酸氢盐浓度。硫酸盐是产酸的，但比氯化物弱，而磷酸一氢盐不影响酸碱平衡的血液测量。
Abstract A study was conducted to determine the relative acidogenicities of dietary supplements of the anions, chloride, sulfate, and monohydrogen phosphate (HPO4−2) in diets of young Leghorn chicks. Chloride supplements ranged from 40 to 240 meq/kg, sulfate ranged from 100 to 240 meq/kg, and monohydrogen phosphate ranged from 120 to 240 meq/kg of diet. Anions were substituted on a charge-equivalent basis for dietary carbonate (CO3–2) at 7 to 10 days of age, and blood samples were taken for measurement of blood hydrogen ion concentration, carbon dioxide tension, and bicarbonate concentration (calculated) on the 1st day and after several (usually 8) days of experiment. The effects of anions on acid-base balance were evident on the 1st day and generally persisted for the duration of experiments. Chloride consistently depressed blood pH and blood bicarbonate concentration. Sulfate was acidogenic, but less so than chloride, whereas monohydrogen phosphate did not affect blood measures of acid-base balance.
