Why Did The Chicken Cross the Road? To Cool Off!
It is estimated that around 65 billion broiler chickens are consumed by humans every year. Yet, how much do we really know about them? Today’s guest is doing fascinating and important research in animal behaviour, particularly chickens. Dr. Oluwaseun Sera Iyasere is a specialist in Animal Behaviour and Welfare and a Senior Lecturer in the Department of Animal Physiology, at the Federal University of Agriculture in Abeokuta, Nigeria (FUNAAB). She teaches courses in several subjects including Comparative Animal Behavior, Environmental Physiology, and Animal Welfare. She has more than 45 published journal articles to her credit including several relating to heat stress on chickens. She will share with us several interesting studies regarding chicken behaviour so we can understand these important animals a little better.
