Abstract: Acid detergent fibre was determined on 50 grass samples of known in vivo dry matter digestibility with and without a preliminary extraction with neutral detergent. Pretreatment with neutral detergent reduced the mean yield of acid detergent fibre from 41.5 to 36.8%. This decrease in acid detergent fibre was mainly due to a reduction in the level of ash which accounted for 57% of the difference in fibre level. The error in predicting dry matter digestibility of all feeds from acid detergent fibre was ±3.5 digestibility units and was increased to ±3.8 units following neutral detergent pretreatment. When acid detergent fibre was expressed on an ash-free basis the corresponding residual standard deviations were ±4.4 and ±4.5 units, respectively. It was concluded that a pretreatment with neutral detergent or expressing results on an ash-free basis did not improve the accuracy in predicting dry matter digestibility from acid detergent fibre. |
