What is the duration it takes for a layer to pass food through her system from entry to exit?

  1. 1 hour

  2. 2.5 hours

  3. 4 hours

  4. 6 hours

The correct answer is: 2.5 hours

The correct duration for a layer to pass food through her system from entry to exit is approximately 2.5 hours. This timeframe is a reflection of the efficient digestive system that chickens possess, which allows them to convert feed into energy and essential nutrients quickly. Chickens, being primarily monogastric, have a relatively streamlined digestive process that facilitates rapid nutrient absorption, making this duration plausible. Understanding this time frame is critical for those involved in poultry management, as it affects feeding schedules, nutrient availability, and the overall health of the birds. Efficient digestion aids in maximizing production, particularly in laying hens, where consistent feed intake is crucial for egg production. Proper timing also helps in managing flock health, as it allows for adequate space between feeding and other activities, reducing stress and potential digestive issues.
