Serum IgY antibody levels against C. perfringens NetB in hens after sub-cutaneous immunization with vaccines. The levels of anti-NetB specific IgY antibodies were measured by ELISA and expressed as the average optical density at 450 nm of the standard dilution used. The error bars represent SEM. (a) Serum anti-NetB IgY levels of vaccinated hens at 30 weeks of age (4 weeks post final vaccination). (b) Serum anti-NetB IgY levels of vaccinated hens at 40 weeks of age (14 weeks post-final vaccination). *p < 0.05, **p < 0.01.
