In Brazil ruminant production is based mainly on extensive systems in which forages are the most important, if not the only, source of nutrients. The quality of tropical forages declines seriously with advancing maturity and in extensive systems large amounts of forage commonly remain unused after grazing during the wet season (spring/summer). This unused forage could be harvested and sun-dried. During the dry season, there is a lack of feed on pastures and the hay produced from unused forages could provide a cheap alternative to concentrate supplements. The objective of this experiment was to evaluate three commercially available tropical forages as sheep feed in the Piracicaba river region of Sao Paulo State in Brazil.
