From the outside, this may appear as reduced feed intake, smaller egg size, or lower shell quality. However, these visible effects are the outward signs of a silent defence mechanism working at […]

Heat stress (HS) is one of the most significant environmental stressors limiting productivity in poultry. Especially during summer, the combination of high temperature and humidity disrupts the physiological balance of laying hens, negatively affecting production performance, immune health, and overall welfare. Because chickens lack sweat glands and have limited mechanisms for heat dissipation, they are […]
