Abstract

Feeding dry foods supplemented with urine acidifier (D,L-methionine (Met) or ammonium chloride) decreased urinary pH and struvite activity product in clinically normal cats. As a result, the number of struvite crystals in urine was greatly reduced. Supplementation with 3% Met but not 1% Met caused decrease in the urinary concentration of sediment, which resulted from a reduction in the HCl-soluble fraction. The concentration of HCl-insoluble sediment was not affected by supplementation with the urine acidifier.

摘要

给临床正常的猫喂食添加了尿酸化剂（D，L-蛋氨酸（Met）或氯化铵）的干粮，会降低尿液pH值和鸟粪石活性产物。结果，尿液中鸟粪石晶体的数量大大减少。补充3%的蛋氨酸而非1%的蛋氨酸会导致尿液中沉淀物浓度降低，这是由于盐酸可溶部分减少所致。补充尿酸化剂对盐酸不溶性沉淀物的浓度没有影响。
