What does high ammonia level in the broiler house typically cause?

  1. Enhanced growth

  2. Decreased feed consumption

  3. Improved egg production

  4. Better feather development

The correct answer is: Decreased feed consumption

High ammonia levels in a broiler house typically lead to decreased feed consumption. Ammonia is a gas that can be harmful to poultry health, and elevated levels often cause respiratory irritation in broilers. This discomfort may lead to a reduction in their overall feed intake as the birds may become lethargic or feel unwell. When birds experience respiratory stress, they may prioritize breathing over eating, which can adversely impact their growth performance and overall health. Moreover, excessive ammonia can affect the physiological state of the birds; they may feel stressed or experience reduced appetite, resulting in poorer feed conversion ratios. Thus, the direct impact of high ammonia levels is a decrease in feed consumption, which is essential for optimal growth and development.
