Effect of Ascorbic Acid Supplementation on HSP70 and Plasma Corticosterone Profile During Heat Stress in Broiler Chickens

摘要

Changes in plasma corticosterone and HSP70 profile in tissue lysates of broiler birds under heat stress along with or without vit-C supplementation have been studied in this investigation. The levels of corticosterone and HSP70 were significantly higher in heat stressed (40°C) broiler birds in comparison to control group (26°C). Supplementation of vit-C reduced the level of plasma corticosterone and HSP70 in tissue lysate indicating better capability to sustain under heat stress conditions.
