Data are reported on the voluntary intake and digestibility by sheep of five species of Digitaria when grown as swards, cut at five different stages of growth. Digitaria setivalva was superior to the other four species in in vivo digestibility of the dry matter, organic matter and energy, content of metabolizable energy, voluntary intake of dry matter and voluntary intake of metabolizable energy. This superiority was associated with a higher content of digestible neutral-detergent solubles and cellulose. The metabolizable energy contents of the grasses were significantly correlated with dry matter digestibility and organic matter digestibility, content of digestible dry matter and concentrations of crude protein, neutral-detergent fibre, acid-detergent fibre, lignin and combinations of these different fractions.
