Abstract
The effect of including Aflatoxin (AF) and mycofix in broiler diets on antibody titers against infectious bursal disease virus (IBDV) was evaluated. A total of 480 broilers were distributed into a completely randomized three experiments (160 birds/each) with four levels of AF (0, 2.5, 3.5 and 5 parts/10⁶, and four levels of mycofix (0, 0.05, 0.15 and 0.25%), totaling eight treatments with two replicates for each experiment. Chicks were vaccinated at 7 and 14 days of age with infectious bursal disease live vaccine (CEVA, winter field 2521 G-16)). For antibody analyses, Enzyme-linked immunosorbent assay (ELISA), was used, and blood samples were collected at 28 days of age by jugular vein puncture. The inclusion of mycofix, was effective in stimulating the humoral immune responses against IBDV with each increase of its level of inclusion. Only the highest high level (0.25%) of mycofix inclusion, resulted in significantly (P<0.05) returning ELISA antibody titers against IBDV in chicks fed all levels of AF to those of the control values.
