Effects of vaccination with profilin plus QCDC on body weight gain. Eighteen day-old embryos were immunized with PBS (control), QCDC alone (QCDC), profilin alone (Profilin), or profilin plus QCDC (Profilin/QCDC). Chickens were uninfected or orally infected with 1.0 × 10⁴ sporulated oocysts of E. maxima at 7 days post-hatch, and body weight gains between 0 and 9 days post-infection were calculated. Each bar represents the mean ± SEM (n = 12). Bars not sharing the same letters are significantly different according to the Tukey's HSD test (P < 0.05).
