^apHw: manure pH determined with H₂O; C_tot: Total C, (%); N_tot: Total N, (%); N_H2O: Water-extractable N (%); ADF: Acid detergent fiber (%); ADF-N: the concentration of nitrogen in ADF (%); N_adf: the product of ADF and ADF-N (%); P₂O₅: Phosphorus, (% P₂O₅); K₂O: Potassium, (% K₂O); S: Sulfur, (%); Ca: Calcium, (%); Mg: Magnesium, (%); Na: Sodium, (%); Zn: Zinc (ppm); Fe: Iron, (ppm); Mn: Manganese, (ppm); Cu: Copper, (ppm); B: Boron, (ppm). Values are corrected to a dry weight basis for manure dried at 55 °C for 72 h (9% moisture content). Mean and standard errors (SEM) are arithmetic
^bAnimals (n = 10), fed collectively, were supplied with a mixed daily ration composed of 9.53 kg oat hay, 907 g of corn, and 907 g of peas, animal ⁻¹ day⁻¹
