| dc.description.abstract | Present study was carried out for comparative evaluation of some indigenous and exotic breeds of domestic chicken with regard to the innate immune response, adaptive immune response and resistence to infection following challenge with infectious agent. One exotic (RIR) and two indigenous breeds (Kadaknath, Uttara fowl) were used for study. All the birds were reared in deep litter system with ad-libtum feed and water throughout the experiment. The experiment lasted for 60 days. Significant difference was observed among parameters studied viz; mean total leukocyte count, differential leukocyte count, leukocrit, serum globulin, A/G ratio, phagocytic activity and opsonocytophagic index, among various breeds of chicken at all stages and all the innate and adaptive immune parameter was significantly higher in RIR compared to Kadaknath and Uttara fowl breed of chicken. The RIR showed highest hemagglutination inhibition titre following NDV immunization till the end of the experimental period followed by Kadaknath and Uttara fowl. Cell mediated immune (CMI) response was also observed to be higher for RIR breed compared to Kadaknath and Uttara fowl. The lymphocyte stimulation index was highest in RIR and the lowest in Uttara fowl. Maximum mortality was observed in Uttara fowl up to 15 days post challenge with a virulent virus and antibody titre was maximum in RIR breed at 3 and 7 days post challenge but at 14 days post challenge kadaknath showed highest antibody titre. | en_US |
