Sažetak
Three groups of 362 broilers were fed a corn/soy based feed, of which in two groups 30% corn was replaced with 30% contaminated corn (final level of DON=2.03 ppm). One of these two groups received Mycosorb (Alltech Inc., USA) at 2 kg/T. Body weight and feed consumption was measured at 42 days of age by sampling at random 50-75 animals per group. At 14 days of age, animals were vaccinated against IBD and blood titers were taken from 20 animals per treatment at 14, 21, 28, 35 and 42 d of age and analysed for titers. Statistical analysis on the blood titers was performed by Anova, followed by Duncan post hoc test. The results demonstrate that feeding DON contaminated corn reduced the end weight at 42 d from 2166 g for the control to 2090 g for the DON fed group, but adding Mycosorb restored the end weight to 2198 g. The IBD antibody titer was significantly reduced (P<0.05) at 21 d in serum of animals fed DON contaminated feed. Adding Mycosorb resulted in titers which were comparable with the titers of the control group. The coefficient of variation (CV, =STD/Average*100) of the titers of the DON fed group at 21 and 28 days was about twice the CV of the titers of the control or the Mycosorb fed group. It can be concluded that feeding 2.03 ppm DON reduce immunity response to vaccination and end weight and this effect could be counteracted by feeding Mycosorb.
