Abstract :

Heat stress is one of the most important issues affecting poultry production in tropical countries like India. The production performances and biochemical parameters of chicken were severely affected by elevated temperature. The objective of present study was to assess the effect of high environmental temperature on histology of some of the internal organs of four chicken varieties. The experimental birds were subjected to increased heat treatment i.e., 450 C daily, 2 hours for two weeks period (fifth and sixth week) using artificial heating systems. After the heat treatment, organs were collected and histology of these organs was studied. The results of the study demonstrated that high temperature caused pathological lesions in the liver and bursa of Faicius of oiler, crossed and assel except the crossed birds. However, there was no significant changes were observed in other experimental organs.
