Daily administration of 48.8 mg/ml/bird of the nutrient mixture at 7 -14 days of age to birds challenged at 7 days of age with H9N2 avian influenza virus resulted in improvement in body weigh and significant reduction in feed conversion ratio at 14 days, associated with a significant increase in liver weight index, significant increase in cecal fermentation and complete absence of toxicity signs, In addition, nutrient supplementation had significant improvements in the following parameters: absence of rales at 3 days post H9N2 challenge, absence of tacheitis and enteritis at 7 days spot challenge and significant reduction in mucus accumulation and counts of inclusion bodies-associated heterophils in the trachea.
