Means within a row lacking a common superscript letter are different (P < 0.05).
GE = gross energy; DE = digestible energy; ME = metabolizable energy; DMB = dry matter basis.
Fecal scores were evaluated using a scale of 1 to 5 with: 1 = hard, dry pellets; 2 = dry, well-formed; 3 = soft, moist, formed; 4 = soft, unformed; 5 = watery liquid.
DE = calculated using following equation: kcal/g gross energy × energy digestibility.
ME = Calculated using modified Atwater: 8.5 kcal of ME/g of fat + 3.5 kcal of ME/g of CP + 3.5 kcal of ME/g of N-free extract.
ME = Calculated using unmodified Atwater: 9 kcal of ME/g of fat + 4 kcal of ME/g of CP + 4 kcal of ME/g of N-free extract.
ME = Calculated using NRC equation: DE – (0.77 × g protein of diet).
