The effects of a megalevel of vitamin C on the immune response of the chicken.
Birds fed diets supplemented with 1% vitamin C experienced significant increases in serum levels of vitamin C. Cell-mediated immunity and antibody response to sheep red blood cells, a T-cell dependent antigen, were not influenced by feeding megalevels of vitamin C. However, the antibody response to a T-independent antigen, Brucella abortus, was lower in neonates and higher in adults in the presence of increased levels of vitamin C.
