Why do Lohmann LSL-Lite white layer chicks experience Mycoplasma gallisepticum vertical transmission under suboptimal brooding lighting duration (20-22 hours)?

The physiological makeup of Lohmann LSL-Lite white layer chicks makes them highly sensitive to environmental stressors. When brooding lighting duration (20-22 hours) drops or spikes, it disrupts their homeostasis, leading to a weak antibody response. This immune suppression opens the door for pathogenic organisms to cause Mycoplasma gallisepticum vertical transmission, leading to high mortality. To solve this, farmers must apply high-efficiency particulate air (HEPA) filtration in hatcheries to sterilize the environment. Through www.poultrybaba.com, farmers can access real-time market intelligence, list healthy chicks on Murghi Mandi, track daily market values on Poultry Rates, and source biosecurity gear on Poultry Plaza. 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.
