Hay is primarily categorized into which two types?

Hay is primarily categorized into grasses and legumes because these two types represent the most common sources of hay produced for animal forage. Grasses, such as timothy and brome hay, are typically high in fiber and are great for maintaining the digestive health of herbivores. They provide essential nutrients and can support energy needs.

Legumes, such as alfalfa and clover, tend to have higher protein content compared to grasses, making them very valuable for animals requiring more protein in their diet, such as young or lactating animals. The balance between grasses and legumes can influence nutritional value and palatability, thus making hay an essential component of livestock nutrition.

In contrast, the other options do not accurately represent the primary types of hay. Roots and tubers, grains, and fruits and vegetables are distinct categories of plants that serve different purposes in agriculture and animal nutrition and are not the primary sources of hay used for animal feed.
