Nearly what percentage of total feed used for sheep in the United States is roughage?

Roughage plays a crucial role in the diet of sheep, primarily due to their digestive system, which is designed to process high-fiber forage. In the United States, sheep diets consist predominantly of roughage, as this type of feed provides essential fiber that supports healthy rumen function and overall digestive health. Roughage is not only important for maintaining appropriate gut motility but also helps in nutrient absorption and in preventing digestive disorders.

The significance of roughage in the sheep's diet can be attributed to their natural grazing behavior, where they consume a variety of forages such as grass, hay, and other fibrous plant materials. This high proportion of roughage is necessary to meet their nutritional needs, ensuring they receive adequate energy and protein while promoting optimal weight gain and reproductive performance. Given these factors, nearly 90% of the total feed used for sheep in the United States being classified as roughage accurately reflects the essential role it plays in maintaining the health and productivity of sheep.
