Roughage quality describes the nutritional and functional value of roughage in animal feed. It not only concerns crude protein or energy, but also fiber structure, digestibility, dry matter content, and preservation quality. High-quality roughage supports rumen function, feed intake, and stable digestion in ruminants.

Factors influencing roughage quality include crop choice, harvest stage, weather conditions during harvest, ensiling technique, and storage. Young harvested roughage is generally richer in energy and protein, while later mowed roughage contains more structural fiber. A good balance contributes to animal health and efficient feed conversion.
