What is difference between forage and roughage?

Answer 1

Forage refers to plants or plant parts consumed by grazing animals, such as grasses, legumes, and forbs. Roughage, on the other hand, is a broader term that includes both forages and other fibrous materials like hay, straw, and silage. While all forages are roughages, not all roughages are forages. Roughages provide bulk in the diet and aid in digestion, while forages specifically refer to plants grazed by animals.

Answer 2

Concentrates are foods that are high in digestibility, but low in fiber. (For example: hay, silage, etc.)
Roughages are foods that are low in digestibility, but high in fiber. (For example: corn, oats, barley, etc.)

Answer 3

forage is part of the vegetation that is available and acceptable for consumption (green, ensiled, cured, weathered) and roughage is the part of a plant that is high in fiber and low in TDN (total digestible nutrition).
