Effect of Corticosterone on Growth and Welfare of Broiler Chickens Showing Long or Short Tonic Immobility

摘要：

　　Tonic immobility (TI)test is commonly used to assess the fear.Animals showing different TI duration demonstrate distinct behavior and biochemical responses to stress.However,less is known how TI phenotype affects growth and welfare of domestic fowls.In this study,broiler chickens were classified into short and long TI duration (STI and LTI)phenotypes and treated chronically with vehicle (CON)or corticosterone (CORT).STI broilers demonstrated significantly higher growth rate with higher breast muscle yield (P<0.05)and lower liver weight (P = 0.053)relative to body weight,which was accompanied by higher serum concentration of CORT (P<0.05)and uric acid (P < 0.01),but lower serum level of T4 (P =0.01).
