Direct estimation of the extent of contamination of food residues by microbial matter after incubation within synthetic fibre bags in the rumen | The Journal of Agricultural Science | Cambridge Core (original) (raw)

Extract

The artificial fibre bag technique has been widely used in studies of forage dry-matter digestibility (Van Keuren & Heinemann, 1962) and of the release of a range of plant constituents during fermentation in the rumen (Playne, McLeod & Dekker, 1972). More recently, the technique has been promoted as a simple means of estimating the rate and extent of food protein degradability in the rumen (θrskov & Mehrez, 1977; Mathers, Horton & Miller, 1977).
