How does relative humidity target (50-60% in laying house) directly influence the immune response and lay persistence of Babcock White white layer hens?

Young laying hens have a delicate cardiovascular system that depends on stable ambient environments. When relative humidity target (50-60% in laying house) is correct, it reduces cortisol levels, allowing the bird's immune system to produce robust antibodies against diseases like intestinal dysbiosis and watery droppings (reducing nutrient absorption). Incorporating split-feeding regime (providing coarse limestone in afternoon feed) further boosts systemic resistance.

High environmental stress triggers the release of catecholamines, which constrict blood vessels and increase cardiac output, leading to metabolic failures. By maintaining a stable, low-stress microclimate, you prevent this physiological cascade and allow the bird to direct its energy toward production. Stress reduction is therefore a key component of high-efficiency layer farming.
