1. Digestion: The crop acts as a temporary storage organ for food that has been ingested by poultry. It allows for the initial breakdown and softening of feed before it enters the rest of the digestive tract.
2. Fermentation: The crop also serves as a site for fermentation of feed, where beneficial bacteria can break down complex plant materials and produce nutrients that are easier for the bird to digest and absorb.
3. Water absorption: The crop helps in the absorption of water from the feed, ensuring proper hydration for the bird. It also aids in the regulation of feed passage and nutrient absorption in the digestive tract.
