Shafey, T.M., Al-Mufarej, S., Shalaby, M.I. and Jarelnabi, A.J. 2001. Effects of mannan oligosaccharides on antibody response to infectious bronchitis, infectious bursal disease and Newcastle disease in chickens. J. Appl. Anim. Res., 19: 117-127.
The effects of feeding a mannan oligosaccharide (Bio-Mos) from 0 to 3g/kg diet on 1 to 35 day serum total protein, albumin and globulin and on antibody response to infectious bronchitis (IB), infectious bursal disease (IBD) and Newcastle disease (ND) vaccines of meat (experiment 1) and specific pathogen-free (SPF) (experiment 2) chickens were examined. A general vaccination program was used against IB, IBD and ND with half of the birds per diet receiving a booster dose of IB and ND vaccines at 12 day of age in experiment 1. Whilst, all birds in experiment 2 were vaccinated with the booster dose, Bio-Mos (BM) did not influence antibody titers of IB, IBD and ND and serum albumin of chickens. Serum globulin and total protein were influenced by dietary addition of BM in SPF chickens but not in meat chickens. It was concluded that the addition of BM to the diet of chickens did not significantly influence the immune response to IB, IBD and ND vaccines in meat and SPF chickens.
