Methods: Broilers: 1.Using 3 different Chinese herbs (Astragalus membranacevs, Codonopsia pilosula, Acanthopanax senticosus) with 5 different concentrations (1-5%) in feed additives to identity Minimum Effective Concentration for each herb. 2.With Minimum Effective Concentration of each herb as groups and control group, antibiotic added group to conduct comparison experiments for production performance and immunity effects. Hens: 1.Newly hatched chicken are raised through brooding, growth and finishing periods, experimens are conducted after 18 weeks of age. 2.Three Chinese herbs (Astragalus membranacevs, Codonopsia pilosula, Epimedium brevicornum etc.) with 3 different concentrations (1, 3, 5%) each are used plus control group too feed hens. 3.During experimental period, record food intake, egg production rate each week. In the beginning of test and the end of each month analyze egg weight and Hought’s unit of egg. Blood samples are also collected to analyze blood chemistry, and immunity effects.中草藥雞免疫生產性能Chinese herbs medicinechickenimmunityproduction performance
