Mycofix ameliorative effect on Newcastle disease antibody production in broiler chickens during aflatoxicosis

الملخص EN

Three experiments were conducted to elucidate the alleviation effects of Mycosis plus 3.0 on Newcastle antibody formation during aflatoxicosis in broiler chickens.

Three levels of Mycosis (0.05 %, 0.15 %, and 0.25 %) and afflation (2.5ppm, 3.

5 ppm, and 5 ppm) were used.

Chickens were vaccinated at 8 and 18 days of age.

Enzyme-linked immunosorbent assay and Haemagglutination inhibition tests were employed for determination Newcastle antibody titers at 28 days.

The results showed that, Mycosis, and only at its high level of addition (0.25 %) was effective in ameliorating the negative effect of afflation at the rates 2.5ppm and 3.5 ppm levels of inclusion on antibody production but not at the high level of 5ppm on antibody production, comparing with titers in control groups.
