Market Broiler Management Practice Test

What is the recommended maximum air speed measurement for broiler chickens at specific developmental ages?

1. 150 ft/min

2. 175 ft/min

3. 200 ft/min

4. 250 ft/min

The correct answer is: 175 ft/min

The recommended maximum air speed measurement for broiler chickens is crucial for their welfare and growth. At various developmental stages, broilers are sensitive to environmental conditions, including air speed, which can impact their behavior, health, and growth performance. The selection of 175 ft/min reflects a balance that ensures adequate ventilation without causing stress to the birds. Excessive air speed can lead to discomfort, as the chickens may face difficulty in thermoregulating themselves. A moderate air speed allows for effective air exchange, helping to maintain a suitable temperature and humidity level in the housing environment, which is essential for optimal growth and feed conversion. For younger birds and during certain ages, air speeds that are too high can lead to chilling effects or respiratory issues. Therefore, the recommended air speed of 175 ft/min helps mitigate these risks while still promoting good air flow necessary for ammonia and humidity control within the poultry house. Understanding these environmental needs is critical in broiler management to promote health, welfare, and productivity throughout their growth period.
