Description
Tropical pasture species are of well-known lower quality than temperate species and there is evidence that some tropical legumes may contain antiquality factors that reduce further their nutritive value. Nonetheless, the nutritive value of Neonotonia wightii is generally moderate to high (Pizarro et al., 1983 ; Ribeiro et al., 1980), although there is little information on the factors that affect its quality, and none on the rate and sites of digestion within the gastrointestinal tract of ruminants. The aim of the work reported here was to examine the effect of age on the chemical composition, apparent digestibility and sites of N digestion of two Neonotonia wightii cv Tinaroo hays made at different ages of regrowth.
