Market Broiler Management Practice Test

The recommended duration of darkness for broilers at a weight exceeding 3 kg is how long?

1. 6 hours

2. 10 hours

3. 12 hours

4. 14 hours

The correct answer is: 12 hours

For broilers that have reached a weight exceeding 3 kg, providing an appropriate duration of darkness is essential for their well-being and optimal growth. The recommended duration is 12 hours of darkness. This period allows them to rest adequately, which is crucial for their recovery and overall health. In the context of broiler management, light exposure influences growth rates, feed consumption, and overall behavior. A balanced lighting program that includes extended hours of darkness helps prevent stress, supports natural circadian rhythms, and enhances the birds' ability to utilize feed effectively. The other durations, while they might seem appropriate, do not align with the established best practices for broiler management at this weight. For instance, durations shorter than 12 hours might not provide sufficient rest, while extending beyond 12 hours could hinder their growth and lead to decreased feed efficiency. Therefore, the 12-hour darkness period strikes an optimal balance for promoting growth while allowing the birds the necessary time to sleep and recover.
