Structure, quality, and skills interact to influence forage intake
Utah State University Extension
In general, the more livestock eat, the more weight they gain or milk they produce. Thus, forage intake is key to animal performance. Agronomists manage for plant density and height to ensure livestock maximize intake. While plant structure is important, intake is not dictated by structure alone. Forage quality, current nutritional state, and experience also affect forage intake by livestock.
