High fibre and low energy feeds are classified as

High fibre and low energy feeds are classified as roughages. Roughages are feed materials that are high in fibre and low in energy, such as hay, straw, and silage. These feeds are often bulky and take longer to digest, providing sustained energy over a longer period of time. Roughages are an important component of the diet for ruminants like cows and sheep, as their digestive systems are adapted to break down fibrous plant material. In contrast, concentrates are feed materials that are high in energy and low in fibre, such as grains and oilseed meals. They provide a quick source of energy and are often used to supplement roughages in an animal's diet.
