| 摘要 |
The invention provides methods for predicting urine pH for an animal by determining the amount of selected cations, anions, and sulfur-containing amino acids in a food for consumption by the animal and predicting urine pH using a formula that equates the amount of such cations, anions, and sulfur-containing amino acids to urine pH. Generally, the amounts of all or a subset of the cations sodium, potassium, calcium, and magnesium; the anions are chloride, sulfur, and phosphorus; and the sulfur-containing amino acids methionine and cystine in a food are used to predict animal urine pH when the food is consumed by the animal.
