Effects of Dietary Supplementation of Plant Extract (Impim) on Growth Performance Immune Status, and Nutrient Digestibility of Broiler Chickens

The effects of dietary supplementation of plant extract (Impim) on growth performance, immune organ indexes, serum biochemical indicators, and nutrients digestibility of broiler chickens. Nine hundred one-day-old Cobb commercial broilers were randomly allocated into 3 treatments with 3 replicates in each treatment with 100 broilers in each replicate. The 3 dietary treatments were 1) control group (CON), basal diet; 2) CON + 0.02% Impim (Impim group); 3) CON + 0.002% Colistin sulfate premix + 0.004% Aureomycin premix. The trial period were 53 days. The results showed that, compared with antibiotic group, the serum total protein, amylase activity and lipase activity of broilers fed with Impim had been significantly improved by 9.91%, 18.25% and 14.73%, respectively (P 0.05) in broilers of Impim group than antibiotic group. It could be concluded that administration of the Impim to broilers’ diet improved chickens’ growth performance, had a potent immunomodulatory effect (potentiated immune response). Eventually, Impim could be used as a partial replacement to the antibiotics.
