Abstract

Rumen microbial attachment to food particles had a significant negative correlation with cell wall contents, cellulose and acid-detergent fibre (ADF) (P < 0·01) and a non-significant correlation with lignin, total phenolic content, condensed tannins and protein precipitation capacity. Microbial colonization was significantly positively correlated with in sacco dry-matter loss (DML) at 48 h of rumen incubation (P < 0·01). The cell wall contents and ADF were good predictors of DML. The relationship of DML (Y) with cell wall contents (X) and ADF (X') were Y = 1·012 – 0·0011Z, r = –0·89 (P < 0·01, no. = 10) and Y = 0·977 – 0·0014X', r = –0·88 (P < 0·01, no. = 10), respectively.
