Ovotransferrin concentrations in the faeces from birds derived from a necrotic enteritis in vivo trial. The graph represents the ovotransferrin concentration measured by ELISA (mean ± standard error of the means) in faeces from birds that received all predisposing factors but were not challenged with C. perfringens (neg. ctr; n = 8) or from birds challenged with C. perfringens resulting in varying degrees of necrotic enteritis: no necrotic lesions (score 0; n = 8); mild intestinal necrosis (score 2; n = 8); moderate necrotic enteritis (score 3–4; n = 8) or severe necrosis (score 5–6; n = 8). *p < 0.05.
