Effect of commercial pearling on digestible energy (DE) value, crude protein (N) and amino acid (AA) digestibility of DON-contaminated barley fed to pigs was evaluated. Six barrows with an initial body weight (BW) of 52.5 ± 2.7 kg and fitted with a simple T-cannula at the distal ileum were assigned to three dietary treatments according to a replicated 3 x 3 Latin square design. The experimental diets contained pearled DON-contaminated barley: 1.2, 4.4 and 7.6ppm DON as the only source of energy and N in the diet. Chromic oxide (0.4%) was added as the digestibility marker. Daily feed allowance for the pigs were fixed at 2.6 x maintenance energy requirements based on the BW of the pigs at the beginning of each experimental period. Feed was offered at 8:00 and 16:00 h. Experimental periods lasted 8-day with 4-day of adaptation to experimental diets followed by 2-day each of fecal and digesta collections for energy, N and AA digestibility. DE values for 1.2 and 7.6ppm DON barley diets were significantly (P < 0.05) higher than their predicted values. DE of the 4.4ppm DON diet was similar (P > 0.05) to the predicted value. Apparent ileal N and AA digestibility (AID) values were mostly similar (P > 0.05) amongst diets except for arginine and methionine for the indispensable AAs and glutamic acid, glycine and proline for the dispensable AAs. It was concluded that commercial pearling enhances the nutritive value of DON-contaminated barley for swine.
