Market Broiler Management Practice Test

For optimal growth conditions, how many hours of light should be provided to broilers during their initial rearing period?

1. 12 hours

2. 18 hours

3. 24 hours

4. 30 hours

The correct answer is: 24 hours

Providing 24 hours of light during the initial rearing period of broilers is optimal for their growth. Continuous lighting helps in stimulating feed intake, which is crucial for growth during the early stages. When broilers are exposed to constant light, they are more likely to eat consistently, which supports their metabolic processes and overall development. Moreover, the initial rearing period is critical for establishing proper body weight and muscle development, and continuous light aligns with enhancing these factors. However, while continuous light may be beneficial initially, management practices often adjust lighting conditions as the birds mature to promote health and well-being. Balancing light and dark periods later in their rearing helps regulate behavior and can improve welfare. It's important to consider these adjustments as broilers grow, but for the initial period, continuous lighting is recognized for its supportive role in promoting optimal growth conditions.
