INTRODUCTION: This study compared the efficacy of a Panax ginseng polysaccharide (GPS) and Houttuynia cordata essential oil (HCEO) complex with antibiotics in Arbor Acres broilers.
METHODS: Three hundred 1-day-old broilers were randomly assigned to five groups: a blank control group (C), an antibiotic group (A), and three groups administered the GPS-HCEO complex via drinking water at 0.1 (M1), 0.3 (M2), or 0.6 mL/L (M3).
RESULTS: Compared with Group C, FCR was significantly decreased in Groups M1, M2, and M3 during the early phase (P < 0.05). During the late phase and the overall experimental period, FCR was significantly lower in Groups A, M1, and M3 than in Group C (P < 0.05). For slaughter performance, the four treatment groups showed no significant differences in slaughter rate, semi-eviscerated rate, eviscerated rate, breast muscle rate, leg muscle rate, lean meat rate, or wing rate compared with Group C (P > 0.05), whereas Group A had a significantly lower abdominal fat rate than Group C and the three GPS-HCEO groups (P < 0.05). Serum analysis showed that IgG, IgM, IgA, IL-1, and IL-10 levels remained unchanged compared with Group C (P > 0.05), whereas serum triglyceride levels were increased in all treatment groups (P < 0.05). Antibiotic supplementation impaired duodenal morphology and reduced cecal microbial diversity, as reflected by the Simpson index, as well as the relative abundance of Firmicutes and Tenericutes. Supplementation with 0.6 mL/L GPS-HCEO complex achieved a feed conversion efficiency comparable to that of antibiotics. Unlike antibiotics, the GPS-HCEO complex improved jejunal and ileal morphology, as indicated by increased VH and V/C ratio, without disrupting the core microbial structure. It also promoted the enrichment of the beneficial genera Aerococcus and Jeotgalicoccus in the cecum.
CONCLUSIONS: These findings suggest that the GPS-HCEO complex has potential as a feed additive for reducing antibiotic use in broiler production.
