¹Dietary treatments were based on 2 phases: phase 1 from d 0 until animals achieved 11 kg of body weight (4 d for pig weaning weight > 9 kg and 14 d for pig weaning weight <  7.5 kg) and phase 2 until pigs achieved 20 kg of body weight (17 d for both weaning weight groups). Concentrations determined by mycotoxin screen by liquid chromatography-tandem mass spectrometry (Veterinary Diagnostic Laboratory, North Dakota State University, Fargo, USA)
