2. Grinding food

3. Absorbing nutrients

4. Producing enzymes

The correct answer is: Grinding food

The primary purpose of the gizzard in poultry is grinding food. The gizzard is a specialized muscular organ that plays a crucial role in the digestive process of birds, particularly those that do not have teeth. Since poultry do not chew their food, the gizzard serves as a mechanical processing chamber where food is broken down into smaller particles. This grinding action is often aided by the presence of grit, which is small, hard particles that birds ingest to help with the breakdown of fibrous food materials. This process is essential because it allows for better digestion and nutrient absorption in the intestines. By thoroughly grinding food, the gizzard ensures that the food particles are small enough for enzymes and digestive juices to act effectively in further digestion. Therefore, the gizzard is vital for the efficient processing of food, contributing to the overall health and nutrition of the poultry.
