              Abstract
              
              
              The 
              study was conducted on Vencobb broiler 
              chicks to ascertain the antistress affects of Zist, Zeetress and a 
              combination of Amla and Turmeric during summer, rainy and winter 
              seasons and thereby the haematological changes of birds revealed 
              that during all the three seasons a marked improvement in 
              Haemoglobin was encountered in all the three groups where herbal 
              preparations were supplemented. A marked increase in the 
              lymphocyte count occurred during summer and winter seasons in all 
              the experimental groups of bird as compared to the control group. 
              The heterophil count was decreased with the supplementation of 
              herbal formulations in the feed irrespective of the seasons 
              encountered in the season. This decrease in heterophil count was 
              highly significant in seasons like summer, winter and rainy. This 
              observation proves the hepato-stimulatory, hepato protective and 
              immuno modulating effects of herbal preparations.
