Market Broiler Management Practice Test

What common bedding material, high in moisture, can cause Aspergillosis in broiler chicks?

1. Sawdust

2. Straw

3. Shavings

4. Hay

The correct answer is: Sawdust

Sawdust is recognized as the correct answer because it is a common bedding material used in poultry rearing, but it can retain moisture more than other options. When sawdust becomes wet, it creates a favorable environment for molds and fungi to grow, including Aspergillus species, which are responsible for Aspergillosis. This respiratory disease can significantly affect the health of broiler chicks, leading to increased mortality and decreased growth performance. Using bedding that maintains excess moisture can compromise air quality and hygiene within the broiler housing. Therefore, while all bedding materials can potentially harbor pathogens if not managed properly, sawdust is particularly problematic due to its moisture retention properties and the risks associated with it in terms of Aspergillus growth. Proper management practices, like ensuring adequate ventilation and monitoring moisture levels, are essential to mitigate these risks in broiler production systems.
