Market Broiler Management Practice Test

After 7 days of age, light intensities should be reduced gradually to what level?

1. 0.5-1 lux

2. 5-10 lux

3. 10-15 lux

4. 20-25 lux

The correct answer is: 5-10 lux

After 7 days of age, gradually reducing light intensities to levels of 5-10 lux is important for the wellbeing of broilers. This level of light intensity helps in encouraging natural behavior while minimizing stress for the birds. Proper lighting can influence growth rate, feed consumption, and overall health. As broilers mature, excessive brightness can lead to increased stress, which may negatively affect their growth and development. By maintaining light at 5-10 lux, it allows for sufficient visibility for the birds to engage in normal activities without causing undue stress or discomfort. This range also supports the establishment of a calm environment conducive for the birds as they grow. In contrast, higher light levels could cause overcrowding and increased aggression among the flock, while too low of light might jeopardize their ability to feed properly. Therefore, the 5-10 lux range strikes an ideal balance, promoting both wellbeing and optimal growth in broilers.
