State 5 function of gizzards in poultry animals
1. Grinding food: The gizzard helps poultry animals grind and digest their food by using small stones and grit to break down tough food particles.
2. Mechanical digestion: The gizzard acts as a mechanical organ that churns and mixes food with digestive juices to aid in the breakdown and absorption of nutrients.
3. Regulating food passage: The gizzard helps regulate the passage of food through the digestive system by controlling the rate at which food moves from the crop to the intestines.
4. Absorbing nutrients: The gizzard plays a role in absorbing water and nutrients from the digested food as it passes through the digestive system.
5. Immune function: The gizzard also plays a role in the immune system of poultry animals by filtering out harmful bacteria and pathogens from the digestive tract.
