What is the primary role of fiber in livestock nutrition?

The primary role of fiber in livestock nutrition is to aid in digestion and regulate nutrient absorption. Fiber enhances the digestive health of livestock, particularly ruminants, by promoting the growth of beneficial microbes in the digestive tract. This microbial fermentation process is essential for breaking down complex carbohydrates, which in turn leads to the production of volatile fatty acids that serve as an energy source for the animal.

Additionally, fiber plays a crucial role in maintaining gut motility, helping to prevent digestive disorders such as acidosis and bloat. By regulating the speed at which feed passes through the digestive system, fiber also impacts the efficiency of nutrient absorption, ensuring that animals can adequately utilize the nutrients provided in their diet. Thus, a diet high in fiber is necessary for optimal digestive function and overall health in livestock.
