¹The basal diet was used throughout the trial period (from day 80 gestation until the piglets were weaned on day 21 of lactation).

²CP was an analyzed value, whereas the other nutrient levels were calculated.

³The vitamin and mineral premix supplied per kilogram of complete diet: 100 mg Zn (ZnSO₄·H₂O), 80 mg Fe (FeSO₄·H₂O), 22 mg Mn (MnSO₄·H₂O), 25 mg Cu (CuSO₄·5H₂O), 0.4 mg I (CaI₂O₆), 0.3 mg Se (Na₂SeO₃), 14,000 IU vitamin A, 4000 IU vitamin D₃, 50 IU vitamin E, 124 mg vitamin K₃, 4 mg vitamin B₁, 10 mg vitamin B₂, 0.04 mg vitamin B₁₂, 4.8 mg vitamin B₆, 40 mg niacin, 20 mg d-pantothenate, 2 mg folic acid, and 0.16 mg d-biotin.
