The impacts of C. perfringens infection on bird performance. The chicks were fed a high-protein diet. On day 20, the chickens were orally infected with C. perfringens culture (2.0~4.0 × 109 colony-forming units per chicken), twice a day for five consecutive days. In addition, uninfected sham control birds were orally given an equivalent volume of BYC culture medium. All the birds were weighed and sacrificed on day 5 post-first infection. (A): The relative body weight gain (RBWG%) between sham control (NV, n = 12) and C. perfringens-infected groups (CP, n = 12). All birds were weighed before C. perfringens infection (CP0) and on day 5 post-infection (CP5). The following equation: (BWCP5–BWCP0)/BWCP0 × 100% was used to calculate the RBWG%. RBWG% values are represented as minimum to maximum (all points). (B): Lesion scores in sham control and C. perfringens-infected groups. Gross pathological lesions were evaluated using the jejunum sections. Gut lesion scores are shown as minimum to maximum (all points). Asterisks indicate significant differences between groups (* p < 0.05 and **** p < 0.0001).
