Abstract

This study was carried out during the period from 2014 to 2015 in the Poultry Research Farm, Department of Poultry Production, Faculty of Agriculture, Menufia University, Shibin El- Kom, Egypt. The aim of this research was to study the relation between immune response and Hsp70 under different (cold (10 ˚C / 76% humidity) and heat (37 ˚C / 57% humidity)) stresses in order to predict the ability of chicks to tolerate these stresses in older ages. Total number of 322 males and females of Norfa chicken were used in 12 wks of age. Birds were divided into three groups according its immunity level (high, low and Control), the previous groups were subdivided into 6 subgroups (3 under heat stress and 3 under cold stress)by using a climatic chamber. These subgroups were subjected to different periods of exposure to stress (acute and chronic). Results indicated that, in acute heat stress experiment,  birds with high immunity levels  which exposed to cold stress for 6 hours had the highest values of Hsp70 (0.056±0.0045) with no significant differences with the other levels except for the birds with high immunity levels  which exposed to high temperature stress for 3 hours. There were no significant differences among all exposure periods for the birds of low immunity level. In chronic heat stress experiment, birds with high immunity levels, which exposed to high temperature for 6 days, had the highest values of Hsp70 (0.086±0.0031) with significant differences (P≤0.05) compared with the other groups. Regarding the birds of the low immunity levels which exposed to cold temperature stress for 6 days had high value of Hsp70 more than the birds which exposed to 3 days. As a conclusion, immunity level can be used as an indicator for heat tolerance for the birds exposed to cold or heat stress.
