¹Diets supplemented with 0, 300, 600, and 1,200 mg/kg levels, respectively.

²BW = body weight.

³ADFI = average daily feed intake.

⁴ADG = average daily gain.

⁵F:G = feed intake to body gain ratio.

⁶Diarrhea rate = number of piglets with diarrhoea during the trial period/(total number of pigs × number of trials days) × 100%.
