Novel approach to reduce cold stress in layers

A new study shows that a warmed perch system, as a thermal device, improves hen health and welfare by reducing cold stress-associated adverse effects in laying hens. Providing warm perches for laying hens has beneficial effects in terms of maintaining body temperature and feed intake without compromising body weight, egg production and egg quality under cold conditions. Besides the frequent and intense heatwaves caused by global climate change, extremely low temperatures during the winter mon
