• Resumen

  • This study investigated the effectiveness of clove and cardamom alcoholic extracts as growth promoters on performance, carcass traits, some blood serum components, immunity parameters, intestinal microbial population and intestinal morphology of broiler chicks. To this purpose, a total of 240 one-day-old broiler chicks (Ross 308 strain) were distributed randomly into three groups in a form of completely randomized design. The experimental groups were subdivided into four replicates with 20 chicks each. The experiment was continued 6 weeks. Chicks were fed by basal diet as control, basal diet contain 300(ml.ton) clove and basal diet contain 300(ml.ton) cardamom alcoholic extract. The result showed that significant increase in FI and BW in clove and cardamom groups while FCR decreased significantly. Using these herbal extracts already reduced abdominal fat and bursa of fabricius percentage while liver and spleen weight percentage increased significantly. Triglyceride and cholesterol levels decreased in treatments and high-density lipoprotein HDL increased. Also, low density lipoprotein LDL level decreased significantly in clove and cardamom groups. As result reveled antibody titers (ND and SRBC) increased significantly in treated groups compared to the control. It was showed that clove and cardamom extracts had significant effects on intestinal microbial population compared to control group. Data showed that Escherichia coli population decreased while Lactobacillus increased significantly compared to the control. We could demonstrate that inclusion of clove and cardamom extracts may useful and have beneficial effects on performance, blood serum components, values of immunity parameters and intestinal morphology in experimental Ross 308 broiler chicks.
