Textile bags are used in the laboratory to analyze the indigestible contents (internal markers) of feedstuffs after in situ ruminal incubation. Information is needed on the rate and extent of degradation in the rumen using bags made from different materials. In situ techniques have been used extensively to measure the degradation of feedstuffs in the rumen. However, in situ techniques are prone to variability. This paper reviews the effects of particle size, the material from which bags are made, pore size, tensile strength of the bags, in situ estimation of the levels of indigestible compounds [indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF), and indigestible acid detergent fiber (iADF)], rumen degradation profiles, and the use of bags made from nylon (50 µm), F57 (Ankom®), and non-woven textile (100 g m−2). © 2015, Agricultural Institute of Canada.
