Wheat gluten is one of the most important proteins in wheat. Lately, it has been used in piglet diets with promising results.
Wheat gluten is a well-known compound in wheat flour that gives common bread its elastic structure. Isolated wheat gluten has been used in piglet diets as a source of protein, as a functional ingredient (it is rich in glutamine), and even as a partial replacement to animal plasma. The last function has drawn the most attention due to the expensive nature of animal plasma, whereas wheat gluten costs considerably less.
