The effect of low dose oral human interferon alpha therapy on diarrhea in veal calves.

Low doses of recombinant human interferon alfa 2a (rHuIFN-alpha 2a), were given orally in milk replacer formula to veal calves to determine the efficacy of rHuIFN-alpha 2a for protection against diarrhea, ear and/or respiratory tract infections common in vealing operations. Calves given rHuIFN-alpha 2a had fewer days and a lower incidence of diarrhea, compared to placebo-treated calves. Calves treated with rHuIFN-alpha 2a had significantly (P < 0.
