1DM = dry matter; OM = organic matter; NDF = neutral detergent fiber; CP = crude protein; EE = ether extract; ME = metabolizable energy.
2Provided (per kg of DM): 100 g of sodium chloride, 12.5 g of zinc, 12.5 g of iron, 12.5 g of manganese, 1,750 ppm of copper, 450 ppm of iodine, and 240 ppm of cobalt.
3Metabolizable energy was calculated according to the beef NRC [18].
