Effect of Qishaozengmiansan on the Immunological Enhancement of IBD Vaccine in Chickens
Abstract：520 7-day-old Hy gray eggs chickens were randomly divided into four groups inculding three experiment groups (0.5% groups, 1.0% groups, 1.5%groups) and a control group. The chickens were immunized with Fabitux (IBD moderate virulence live vaccine) by the method of intranasal immunization and eye-drop vaccination at 14-day-old and were vaccinated through water again at 28-day-old. The effect of Qishaozengrniansan on the immunological enhancement of IBD vaccine were determined by detection of the antibody levels against IBD, spleen index, acidic - naphthyl acetate esterase (ANAE) in peripheral blood lymphocytes and the leukocyte in peripheral blood. The results showed that Qishaozengmiansan could significantly prolong the bursal antibody persistence time, increase the spleen index, bursal index, ANAE's value and the leukocyte.count. So1% Qishaozengmiansan was recommended for clinical application.
