Supplementing OligoPKE at 05 and 1% level had no effect on plasma IgM of chickens at 21 and 35 DOA. However, chickens
fed OligoPKE supplemented diets had higher IgA concentrations than the control at both 21 and 35
DOA, with birds fed 1% OligoPKE diet recorded approximately one fold increased in IgA compared
to control group.
