Market Broiler Management Practice Test

When should ventilation systems be adjusted to assist broiler welfare?

1. Only in the summer

2. During extreme weather changes

3. At the start of each feeding cycle

4. Only when birds are sick

The correct answer is: During extreme weather changes

The correct choice emphasizes that ventilation systems should be adjusted during extreme weather changes because these fluctuations can significantly impact the welfare of broilers. Proper ventilation is essential for maintaining optimal temperature and humidity levels within poultry housing. During extreme heat or cold, birds can experience heat stress or hypothermia, respectively, which can lead to decreased productivity and increased mortality rates. By monitoring and adjusting ventilation in response to weather changes, farmers ensure that the environment remains within a comfortable range for the birds, facilitating better growth, feed conversion, and overall health. This approach helps in reducing stress on the birds, thus improving their welfare and productivity. The other choices do not sufficiently address the broader aspects of broiler welfare. For instance, adjusting ventilation only in the summer neglects the needs for adequate airflow during colder months and doesn't take into account temperature fluctuations. Similarly, only adjusting during feeding cycles or when birds are sick is too reactive rather than proactive; it prevents the optimization of conditions that can avert stress or disease before they occur.
