The Ecklonia cava Kjellman by-product (ECBP) as a feed additive was evaluated in improvement of productivity and immune enhancement against Salmonella Gallinarum (SG). Lohmann Brown chickens proved SG-free were randomly divided into 3 groups of 8 chickens each. Chickens were fed with the experimental diet treatment: T0, Non treatment-commercial feed; T1, commercial feed with 0.5% ECBP; T2, commercial feed with 0.1% Lactobacillus plantarum. In this study, we evaluated the effect of T1 and T2 groups on the body weight and protective efficacy against SG in chickens. The results demonstrated that treatment of T1 group as a feed additive affected significantly body weight gaining in chickens. In addition, T1 group showed a significant different colonization of SG when compared to T2 and T0 groups. We also studied that serum IgG and $interferon-{\gamma}$ levels were significantly different compared with other treatment groups. Therefore, we suggest that ECBP can be used as a good candidate of feed additives in chicken industry.
