96 Cotswold pigs initial body weight (BW) of 5.96 ± 0.12 kg were blocked based on BW and sex. After 1-week adaptation pigs were randomly assigned to 4-dietary treatments: corn diet (control) and 3-diets of pearled DON-contaminated barleys: 1.2, 4.4 and 7.6ppm, respectively. Each dietary treatment has 6 replicate pens of 4 pigs each in a two-phase feeding program: 5 – 10 kg and 10 – 20 kg BW range. Each phase lasted for 2 weeks. Animals were monitored weekly for average daily feed intake (ADFI), average daily gain (ADG) and feed efficiency (FE). There were significant (P = 0.0356) reductions in ADFI for barley diets compared to control; no differences (P > 0.05) in ADG; FE of barley diets were higher (P = 0.0201) compared with control in phase 1. No differences (P > 0.05) in the ADFI and ADG amongst diets. However, there was highly significant (P = 0.0004) difference in the FE as barley diets demonstrated better FE compared with control in phase 2. Overall, there were no differences (P > 0.05) in ADFI and ADG, but with a tendency (P = 0.0626) for a reduction in ADFI of the barley diets compared to control. Barley diets had superior (P = 0.0026) FE compared to control. It was concluded that commercial pearling was effective in reducing DON and fibre contents of DON-contaminated barley to acceptable levels for use in the rations of early-weaned pigs.
