Title: Effect of exposure to a short-duration sound on the stress response of chickens. Author: Gross WB. Journal: Avian Dis; 1990; 34(3):759-61. PubMed ID: 2241704. Abstract: Chickens were subjected to the sound produced by banging on a metal pail (104 decibels) for 30 seconds. Heterophil/lymphocyte (H/L) ratios began to rise 18 hours later, reaching their maximum value (0.62) in 20 hours and returning to pre-stress values after 30 hours. Neither resistance to Escherichia coli challenge infection nor antibody response were altered.[Abstract] [Full Text] [Related] [New Search]
