The treatments A and C were challenged at the age of 25 days, with a virus inoculum velogenico Newcastle disease. Clinical signs, mortality and serology compatible with the disease were evaluated pre and post challenge, conjunctivitis (63) depression (67%), hoarseness (30%), greenish diarrhea (66%), paralysis (20%), nervous ticks (17%), stiff neck (7%).
