Research Program

Dr. Cheng's primary research interest is brain functioning in regulating stress response in farm animals, especially in poultry. His lab studies the cellular and molecular mechanisms of stress-induced neuronal plasticity and behavioral adaptation; and to develop neuroanatomical and neurophysiological quantitative indicators of animal well-being. His current research emphasis is on 1) pain in farm animals, following various management practices, such as beak trimming in poultry; 2) use of probiotics for improving animal well-being; 3) modification of caging environments to improve hen well-being; and 4) prenatal modification of neurotransmitter system for reducing aggression. Integrated morphological, molecular biological, pharmacological and behavioral approaches to the goal have been designed in my laboratory.
