Figure 3

Serum IgY responses of broiler chickens immunized with clostridial proteins. Chickens were immunized subcutaneously with the indicated vaccines on days 7 and 17, challenged with C. perfringens, and the levels of serum IgY antibodies against NetB were measured by ELISA at day 28. Adjuvant only and no treatment groups were used as controls. (a) Birds were immunized and challenged orally with EHE-NE18 (days 24 and 25). (b) Birds were immunized and challenged in-feed with EHE-NE18 (days 26 and 27). (c) Birds were immunized and challenge in-feed with WER-NE36 (days 26 and 27). The error bars represent SEM.
