Effects of traditional Chinese herbal medicines on blood parameters and antibody level in laying hens

A study was conducted to evaluate the effect of traditional Chinese herbal medicines (TCHM) on Hematological Parameters and immunity in chickens, Astragalus membranaceus (AM), angelicae sinensis extract (ASE) and Danggui buxue san (DBS) were used for the study of Hematological Parameters and immunity in order to provide basis for clinical reference. A total of 400 58-week-old hens were randomized into 10 groups. The added TCHM Period was 42 days. The blood index, ND and AI antibody titer were measured. The results showed that DBS significantly increased the count of White Blood Cell (WBC) (P<0.05) and Red Blood Cell (RBC) (P<0.01), the content of Hemoglobin (Hb) (P<0.01) and Packed Cell Volume (PCV) (P<0.01) in 10 mg/kg group; DBS(15 mg/kg) had significant increase on the count of WBC and RBC and the content of Hb (P<0.05);ASE (15 mg/kg) significantly increased the count of RBC and the content of Hb (P<0.05). At the same time, DBS (10 mg/kg) significantly decreased the dropping rate of blood cell at 30min (P<0.01).In addition, DBS (10 mg/kg) could improve the antibody level of ND and AI than control group (P<0.05).This indicated that DBS (10 mg/kg) had the ability on improving hemopoietic function and immunity in chickens.
