Faecal samples from a continuous digestibility trial with Eragrostis curvula were analyzed for cell‐wall contents, acid‐detergent fibre, lignin, asb and N. DM digestibility was regressed on all these fractions and organic‐matter digestibility was also regressed on faecal organic‐matter N. The best predictions of digestibility were obtained by the use of faecal lignin as a percentage of acid‐detergent fibre, and by cell‐wall contents. N was a comparatively poor predictor and it is shown that its relationship with organic‐matter digestibility varies with the level of N in the diet. It is concluded that both lignin and cell‐wall contents could serve as useful internal indicators since their use is unlikely to be biassed by metabolic and microbial contamination.
