^aThe DL-methionine (DLM) and DL-2-hydroxy-4-methylthiobutanoic acid (HMTBA) diets were prepared by adding 1.34 kg of DLM (99 %) and 1.51 kg of HMTBA (88 %), respectively, to 1000.05 kg of the control (CON) diet at the expense of corn. Each diet (per kg) contained 14,200 kJ digestible energy. CP: Crude protein. ^bProvided per kg of diet: vitamin A, 12,000 IU; vitamin D₃, 2800 IU; vitamin E, 100 mg; menadione, 3.5 mg; thiamine, 3.5 mg; riboflavin, 8.5 mg; niacin, 35 mg; d-panthothenic acid, 21 mg; vitamin B₆, 3.5 mg; vitamin B₁₂, 35 μg; d-biotin, 420 μg; folic acid, 2.5 mg. ^cProvided per kg of diet: copper, 10 mg; iron, 120 mg; manganese, 30 mg; zinc, 80 mg; iodine, 0.21 mg; selenium, 0.23 mg; antioxidant, 100 mg; anti-mould additive 500 mg. ^dCalculated according to NRC [10]
