This study examined how different types of dietary fiber affect the health and growth of meat geese. Researchers compared three fiber sources with different levels of solubility: wheat bran (highly soluble), alfalfa meal (moderately soluble), and bamboo meal (low solubility). They found that the highly soluble fiber source improved growth, enhanced immune and antioxidant functions in the intestines, and promoted beneficial bacteria, making it the best choice for geese farming.
