The investigations were carried out in completely randomized experimental design. Chicks were divided into 8 treatment groups, with 4 replicates per treatment and 10 chicks per replicate. Treatments were: 1) negative control group, neither vaccinated against Newcastle disease virus nor given additives; 2) positive control or broilers were vaccinated against Newcastle disease virus + 0 additives; 3,4 and 5) positive control plus diet supplemented with 0.1, 0.2 and 0.3% humate, respectively; 6, 7 and 8) positive control plus diet supplemented with 0.1, 0.2 and 0.3% mannan oligosaccharides, respectively. Broiler was fed corn-soybean meal based diets. For antibody analyses, blood samples were collected by wing veins and the titers of antibody against Newcastle disease virus were determined using haemagglutination-inhibition test. Compared to the positive control, the antibody titers against NDv were determined significantly lower in negative control group from 35 to 42 days of age. This study demonstrated an increase in the antibody titers in broilers fed diets containing HU and also indicate that inclusion of MOS resulted in increased antibody titers against NDv in the third, fifth and sixth weeks of age. Thus immune function could be modified with dietary mannan oligosaccharides and humate supplementation.Read More
