Resumen
The effects of age and dietary vitamin E concentration in the immune response of broiler were studied. A total of 336 Ross 308 chicks with an initial BW of 41.4 ± 2.6 g were randomly assigned to 3 experimental diets, a control diet with no added vitamin E and the same basal diet supplemented with 40 or 160 ppm of vitamin. The experimental unit was the cage with 16 birds and there were seven cages per treatment. At 7 and 21 d of age, 3 birds per cage were slaughtered and their spleen removed for cytokine gene expression analysis by real time RT-PCR. Interleukin 2 (IL2), myelomonocytic growth factor (MGF), and Interferon-gamma (IFNγ) gene expression were selected as indicators of immune system functionality. The expression of IL2, MGF and IFNγ increased (P < 0.05) by 2, 3.6, and 2.3 folds, respectively in birds fed the 160 ppm supplemented diet at 7 d of age when compared to those fed the control diet. No dietary effects were observed in cytokine gene expression in birds at 21 d of age. Under our experimental conditions the inclusion of 160 ppm of vitamin E in the diet enhances immune function during the first week of age of the chicks.
