a Quantities sufficient to supply the minimum amounts of available indispensable and dispensable amino acids as specified below. Compounding practical foods from natural ingredients (protein digestibility ± 70%) may require quantities representing an increase of 40% or greater than the sum of the amino acids listed below, depending upon ingredients used and processing procedures. b In commercial foods with natural ingredients resulting in elevated calcium and phytate content, borderline deficiencies were reported from feeding foods with less than 90 mg zinc per kg (Sanecki et al., 1982). c A fivefold increase may be required for foods of high PUFA content. d Dogs have a metabolic requirement, but a dietary requirement was not demonstrated when foods from natural ingredients were fed. e Overages must be considered to cover losses in processing and storage.

a Adapted from Payne (1965). Calculated metabolizable protein equals food nitrogen minus fecal and urine N (retained N) × 6.25. Calculated metabolizable energy estimates were based on 4 kcal/g of dietary carbohydrate and protein and 9 kcal/g of dietary fat. These requirements are presumed to apply in a thermoneutral environment at moderate levels of activity.

a Calculated by assuming that ether extract was all triglyceride (except for alfalfa products). Thus, values were calculated by multiplying percent ether extract by fraction that was saturated or unsaturated. Alfalfa ether extract was presumed to be 40 percent triglyceride equivalent, and the percentage of ether extract was multiplied by 0.04 and then by the fraction that was saturated or unsaturated.
