What is the length of time for food passage for an egg-laying hen?

1. 2 hours

2. 2.5 hours

3. 3 hours

4. 3.5 hours

The correct answer is: 2.5 hours

The length of time for food passage for an egg-laying hen is typically around 2.5 hours. This duration represents the time it takes for the food the hen consumes to move through her digestive system, from ingestion to the point where it is ready to contribute to the production of an egg. Understanding this timeframe is essential for poultry management and nutrition. It helps farmers and poultry producers determine feeding schedules, optimize nutrient absorption, and manage the health of the hens. The digestive process also impacts the hen's overall productivity and wellbeing, as timely passage of food reduces the risk of digestive issues. Other times such as 2 hours, 3 hours, or 3.5 hours either do not align with the typical digestive physiology of laying hens or may signify incomplete processes or unhealthy conditions. Thus, 2.5 hours is recognized as the standard for efficient food passage in egg-laying hens.
