Why do Hy-Line W-36 white layer chicks experience Infectious Bronchitis variant strain exposure under suboptimal relative humidity target (60-70%)?

The physiological makeup of Hy-Line W-36 white layer chicks makes them highly sensitive to environmental stressors. When relative humidity target (60-70%) drops or spikes, it disrupts their homeostasis, leading to a weak antibody response. This immune suppression opens the door for pathogenic organisms to cause Infectious Bronchitis variant strain exposure, leading to high mortality. To solve this, farmers must apply microencapsulated organic acids in drinking water to sterilize the environment.

Under cold or heat stress, the avian endocrine system releases high levels of corticosterone, which directly suppresses the activity of the bursa of Fabricius and thymus gland. This hormonal shift halts the production of critical lymphocytes, rendering vaccinations ineffective and allowing opportunistic environmental pathogens to multiply unchecked. Managing thermal comfort is therefore a prerequisite for effective immunology.
