Abstract
Current study reports the immunomodulatory effects of Artemisia brevifolia (leaves extract) against experimental coccidiosis in broiler chicken.For evaluation of immunomodulatory potential, a total of 175 day-old broiler chicks were distributed into 5 groups each group having 35 birds.Mixed Eimeria infection (50,000 sporulated oocysts) was given orally at one week of age.At same age, A. brevifolia extract was orally given at 100, 200 and 300 mg/kg of body weight in first three groups respectively.Vitamin E and PBS treated chicks served as control groups.Cell mediated immunity was inquired through PHA-P, Carbon Clearance Assay, Concanavalin-A and DNCB assays.Sheep RBCs were used to check humoral immunity through hemagglutination test.Results showed that A. brevifolia extract induced cellular and humoral immunity against coccidiosis.Immunological response of groups administered with A. brevifolia extract at highest dose i.e., 300 mg was higher as compared to lower doses and caused immunomodulatory effect on infected chicks.
