Market Broiler Management Practice Test

What is the optimum dwarf wall height in a broiler house?

1. 0.30 m

2. 0.50 m

3. 0.70 m

4. 0.90 m

The correct answer is: 0.50 m

The optimum dwarf wall height in a broiler house is considered to be 0.50 m. This height strikes a balance between providing adequate ventilation and maintaining biosecurity while also ensuring that the broilers are protected from drafts and environmental extremes. A dwarf wall of this height allows for sufficient air exchange while minimizing the risk of disease and stress in the birds. It supports proper air circulation, which is crucial for maintaining the health of the flock, reducing the buildup of harmful gases like ammonia, and ensuring that the temperature is regulated within the house. Additionally, a height of 0.50 m helps in preventing too much heat loss during colder months. Other heights, such as 0.30 m, are typically insufficient for adequate ventilation and may allow for more exposure to environmental stressors. Conversely, a height of 0.70 m or 0.90 m may be excessively tall, leading to potential ventilation challenges and making it harder to maintain a biosecure environment due to increased risks of pests and predators entering the space. Therefore, 0.50 m is optimized for the overall welfare and performance of the broilers.
