Market Broiler Management Practice Test

In broiler houses with open sided, natural ventilation and stir fans, what is the maximum stocking density?

1. 20 kg/m square

2. 25 kg/m square

3. 30 kg/m square

4. 35 kg/m square

The correct answer is: 30 kg/m square

In broiler houses equipped with open sides for natural ventilation and utilizing stir fans, the appropriate maximum stocking density is crucial for maintaining bird health and performance. The choice of 30 kg/m² reflects the balance needed between maximizing production and ensuring that the birds have adequate space for movement, access to food and water, and suitable environmental conditions. At this stocking density, ventilation is effective due to the open design and the use of stir fans, which help to ensure an even distribution of fresh air and temperature regulation within the house. This density allows for optimal air quality and reduces stress among the birds, which can lead to better growth rates and overall health. Relation to other choices shows that 20 kg/m² and 25 kg/m² would provide even more space for the birds but do not maximize the potential output per area, making them less efficient. A density of 35 kg/m², on the other hand, would likely compromise the environmental conditions and well-being of the birds due to overcrowding, leading to potential health issues and lower overall productivity. Thus, the options above and below the correct one do not balance the needs of the birds with production efficiency as well as the chosen answer does.
