Use of Cichorium Intybus Leaf Extract as Growth Promoter, Hepatoprotectant and Immune Modulent in Broilers

Abstract

The efficacy of Cichorium intybus (chicory) leaf extract was determined on day-old chicks (n=150) that were distributed in 15 replicates (10 birds/replicate). These replicates were allotted to five treatment groups such that each group received three replicates. Group A (positive control) was offered commercial ration supplemented with antibiotic growth promoter (Enracin) and coccidiostat (Salinomycine) along with water without any supplementation. Group E (negative control) was offered water without supplementation of antibiotic and coccidiostat. Whereas, group B, C and D were offered water containing different concentrations of chicory leaves extract at 5, 10 and 15 ml/L, respectively, extracted in distilled water at pH 7. Supplementation of chicory leaf extract in drinking water of birds exhibited a significantly (P< 0.05) improved weight gain and efficiency of feed utilization. Aspartate Aminotransferase concentration, antibody titer against Newcastle disease, blood glucose, cholesterol level, total leukocyte count (TLC) and hepatoprotective properties were found to be better in treated groups than those of controls. The feed consumption, Alpha Glutamyltransferase, hemoglobin concentration (Hb), Packed Cell Volume (PCV), heterophils count, lymphocytes count and antibody titer against infectious bursal disease remained unaffected. It was concluded that chicory leaf extract can be used an inexpensive, efficient and safe growth promoter in broiler production.
