Vitamin and mineral premix supplied per kg of diets: 3,500 IU vitamin A; 250 IU vitamin D₃; 25 mg vitamin E; 0.052 mg vitamin K; 2.8 mg vitamin B₁(thiamine); 2.6 mg vitamin B₂ (riboflavin); 2 mg vitamin B₆ (pyridoxine); 0.014 mg vitamin B₁₂; 6 mg Cal-d-pantothenate; 30 mg niacin; 0.4 mg folic acid; 0.036 mg biotin; 1,000 mg taurine; 44 mg FeSO₄; 3.8 mg MnSO₄; 50 mg ZnSO₄; 7.5 mg CuSO₄; 0.18 mg Na₂SeO₃; 0.9 mg Ca(IO₃)₂.
Chromium oxide was added into the diet fed 5 d before the end of the experiment.
Metabolizable energy (ME) was calculated follow equation; ME (kcal/kg) − ([CP × 3.5] + [EE × 8.5] + [NFE × 3.5]) × 10.
CON, rice-based diet; TRT, corn-RS-based diet; DM, dry matter; CP, crude protein; NFE, nitrogen-free extract; RS, resistant starch.
