Market Broiler Management Practice Test

What is the recommended relative humidity for chicks aged 28-42 days?

1. 20-30 percent

2. 40-50 percent

3. 50-70 percent

4. 70-80 percent

The correct answer is: 50-70 percent

In broiler management, maintaining appropriate environmental conditions is vital for the health and growth of the birds. For chicks aged 28-42 days, the recommended relative humidity is indeed between 50-70 percent. This range is beneficial for several reasons. Firstly, at this life stage, broilers are developing rapidly and require an environment that supports their growth while minimizing stress. Relative humidity within this range helps to prevent respiratory issues, as excessively low humidity can lead to respiratory irritation, while too high humidity can promote the growth of bacteria and fungi. Additionally, the 50-70 percent humidity level aids in maintaining proper water vapor in the air, which is crucial for the chicks' overall hydration status. Adequate humidity also plays a role in ensuring the litter remains dry and minimizes ammonia build-up, which can harm the birds' health. Moreover, this humidity range facilitates better feed intake and digestion, crucial for optimal weight gain and overall performance in market broilers. Therefore, maintaining relative humidity within 50-70 percent contributes significantly to achieving the best outcomes for the flock during this critical growth phase.
