Abstract

The objective of this study was to evaluate the effects of Pediococcus acidilactici (P. acidilactici) and Saccharomyces cerevisiae (S. cerevisiae) on the growth performance, intestinal lesions and ileal Clostridium perfringens (C. perfringens) count of broiler chickens challenged with C. perfringens induced sub-clinical necrotic enteritis (NE). A total of 150 broiler chicks, allocated into five treatment groups (6 replicates of 5 chicks/cage), were reared in cages for 29 days: T0 (control group, not infected, not supplemented); T1 (infected with C. perfringens, not supplemented); T2 (infected with C. perfringens and coccidia, not supplemented); T3 (infected with C. perfringens and coccidia, supplemented with P. acidilactici); T4 (infected with C. perfringens and coccidia, supplemented with S. cerevisiae). The parameters analyzed were: body weight gain, feed intake, feed conversion ratio, mortality, intestinal lesion score and ileal C. perfringens enumeration by quantitative real-time PCR. The challenge resulted in impairment of growth performance, increased lesion score (≤ 2) and overgrowth of the C. perfringens population. However, the dietary inclusion of P. acidilactici or S. cerevisiae caused a significant improvement in feed conversion, net reduction of gut lesions, as well as a decrease in the intestinal C. perfringens population. In conclusion, these results suggest that dietary supplementation with probiotics (P. acidilactici or S. cerevisiae) could be beneficial to alleviate the negative effects of subclinical NE in broiler chickens.
