Poultry biological characteristics determine high requirements for

ventilation and environmental control

1. Biological characteristics

Three highs:

1) High oxygen demand

2) The body temperature of adult chickens is high (the body temperature of chicks is low: they are afraid of cold stress)

3) Hazardous substances in chicken houses: high levels of carbon dioxide, ammonia, and dust.

2. Ventilation purpose:

1) Emit harmful gases

2) Suitable temperature and humidity for the chicken house

3) Reduce microbial residues caused by bacteria and viruses

3.Ventilation mode

1) Positive pressure

2) Negative pressure

3) Comprehensive
