| Popis: | Effect of prolonged and intermittent exposure to increased atmospheric temperature on the immune responses was studiedexperimentally in 154 broilers. It was observed that 40 ± 1 ° C for 29 days, 12 h. a day depressed both humoral and cell-mediated immunity. There was a reduction in the weight of the lymphoid organs (bursa of Fabricius, spleen and thymus) consequent to depletion of medullary lymphocytes of bursa of Fabricius and a decrease in haemagglutination inhibition titres against N.D. Cell-mediated immunity as assessed by skin test with Con A showed considerable depression. |
