Effects of MOS and heat activated sodium bentonite as aflatoxin absorbents on antibody titers against Newcastle disease and infectious bursal disease viruses in broiler chickens.

摘要: In a completely randomized design, preventive effects of mannan-oligosaccharide (MOS, 0.05 and 0.1% dry matter of diet) and heat activated sodium bentonite (1.5 and 3% dry matter of diet) on aflatoxin detoxification were evaluated and compared. Chicks were fed on different dietary treatments at four replicates from 1 to 42 d of age. Birds were vaccinated against Newcastle disease and infectious bursal disease viruses and sera antibody contents of three birds per replicates measured at different ages. Results of this study clearly indicated that MOS and sodium bentonite addition to diet of broilers effectively diminished the adverse effects of aflatoxin on the investigated titers (P<0.05). The lower dietary concentration of heat activated sodium bentonite and the higher concentration of MOS were found more effective than the other concentrations against the adverse effects of aflatoxin on the antibody titers of …
