The main function of fiber in animal diets is to promote healthy digestion and gut function. Fiber serves as a crucial component of the digestive process, particularly in herbivorous and omnivorous diets where it aids in maintaining proper gut motility and consistency of feces. It helps to bulk up the digestive contents, encouraging regular bowel movements and preventing digestive disorders such as constipation.

Additionally, fiber can act as a prebiotic, fostering a healthy gut microbiome by supporting the growth of beneficial bacteria. This, in turn, facilitates better nutrient absorption and can enhance overall gut health, which is essential for the well-being of the animal. The presence of fiber in the diet also helps to regulate the rate of digestion, which can influence nutrient utilization and overall energy absorption from other dietary components.

While the other options address important aspects of animal health and nutrition, they do not capture the primary role of fiber as effectively. Energy for physical activity is primarily sourced from carbohydrates and fats, reproduction rates are influenced by a variety of factors including hormonal balance and nutrition beyond just fiber, and muscle development relies more on protein intake rather than fiber's contributions.
