Which of the following is not considered grass hay?

Alfalfa is classified as a legume hay rather than a grass hay. This distinction is important because legumes, like alfalfa, typically have a higher protein content and different nutrient profiles compared to grasses. Grass hays, such as Timothy, Bermudagrass, and Orchardgrass, are derived from various species of grass and are generally lower in protein and higher in fiber. Recognizing this difference is key in understanding livestock nutrition and the appropriate feeding practices for different types of forages.
