Roughages are an essential component of most herbivore diets, providing the necessary fiber for proper digestion, with some sources containing over 90% dry matter while others remain high in moisture. Understanding the distinct types is crucial for optimizing animal nutrition, as each form offers different nutritional and physical characteristics depending on how it is harvested and preserved. The three main forms are dry roughages, silages, and pastures.

In 2018, a study published in the Journal of Dairy Science detailed the numerous microbial, chemical, and plant toxin hazards present in silage, highlighting why it is unsuitable and potentially dangerous for humans to eat. Silage is a fermented forage crop, but while it is a nutritional staple for livestock, the human digestive system is neither designed to process it nor equipped to handle the associated health risks.

Over 70% of the feed energy available for livestock worldwide comes from forages and roughages. Understanding the dietary role of these high-fiber feeds is essential for proper livestock management. This guide explains what are the four types of roughage and their nutritional impact.
