Market Broiler Management Practice Test

Evaporative cooling should not be used before the flock reaches what age in days?

1. 14

2. 21

3. 28

4. 35

The correct answer is: 28

Evaporative cooling is a crucial management practice in broiler production, especially in regions with high temperatures. This method helps maintain a comfortable environment for the birds, which is necessary for their optimal growth and well-being. However, before a certain age, broilers are more vulnerable to respiratory issues and stress caused by excessive humidity and temperature changes. The correct age at which to start using evaporative cooling is when the flock reaches 28 days. At this stage, the birds are better equipped to handle the increased humidity that comes with evaporative cooling systems. Younger birds, particularly those under this age, are more susceptible to heat stress and may not effectively regulate their body temperature. Additionally, using such a system too early can create an environment that the developing respiratory system cannot manage, leading to increased mortality and health issues within the flock. Understanding the appropriate timing for introducing evaporative cooling systems is essential for poultry producers to ensure that the flock reaches full potential without the risk of adverse health effects. This timing is particularly significant for young chicks, who require stable and appropriate environmental conditions during their early days.
