The effect of medicinal plant (Sangrovit), probiotic (PrimaLac), and organic acid (Selko-pH) as feed additives, on fecal excretion of Campylobacter (cfu/g) on broilers were evaluated. Other measurements such as performance, immune response and serum lipids were determined. A total of 300 broilers (Cobb 500) were fed unsupplemented diet (negative and positive controls), feed containing probiotic (1g/kg) or medicinal plant (5g/kg) and/or drinking water containing organic acid (1mL/L). All birds except negative control were orally challenged with (109 cfu/mL) C. jejuni at d 21. Fecal samples were collected at d 35 and 42 for Campylobacter count. BW, FI and FCR were determined weekly. The immune response to SRBCs was determined twice during the experiment. Serum lipids were estimated on d 49. Fecal samples in negative control and organic acid groups had the lowest count of Campylobacter (P < 0.05). Moreover, probiotic and Sangrovit groups showed a significant reduction of this bacteria compared with control positive group (P < 0.05). FI of organic acid group was significantly lower than control negative (P < 0.05). Other groups did not have significant differences with these 2 treatments. Highest and lowest weight gain was achieved in control negative and positive groups, respectively (P < 0.05). Lowest and highest FCR observed in control negative and control positive groups, respectively (P < 0.05). On d 49 probiotic, Sangrovit and negative control group had a significant higher immune response compared with control positive and organic acid groups (P < 0.05). The Chol, TG, HDL and LDL levels were not affected by treatments (P > 0.05). This study indicates that the use of probiotic and Sangrovit could be potential treatment for decreasing Campylobacter excretion and improve broilers performance.
