Market Broiler Management Practice Test

What is the maximum air speed across broilers over 28 days of age?

1. 1.0-2.0 ft/second

2. 1.75-3.0 ft/second

3. 2.5-4.0 ft/second

4. 3.5-5.0 ft/second

The correct answer is: 1.75-3.0 ft/second

The maximum air speed across broilers over 28 days of age is ideally maintained at a range of 1.75-3.0 feet per second. This airflow range is crucial for several reasons in the overall management of broiler chickens. First, appropriate air speed helps in maintaining a comfortable environment for the birds. High air speeds can induce stress and discomfort, potentially impacting their growth and feed conversion rates. The specified range ensures that while there is adequate ventilation to manage heat and humidity, the air movements are not so strong as to disturb the birds excessively. Secondly, managing air speed within this range helps optimize the distribution of temperature and humidity within the poultry house. Ventilation systems are designed to provide this balance; exceeding these air speed parameters can create areas of draft that can lead to uneven thermal conditions, affecting the overall health and productivity of the flock. In sum, maintaining the air speed within the range of 1.75-3.0 feet per second promotes a conducive environment for broilers, ensuring their welfare and supporting optimal growth rates.
