Abstract

Cr-mordanted fiber, Cr-impregnated cellulose, 169ytterbium, 51Cr-EDT and PEG were compared as digesta passage rate markers in the stomachs and the whole tract in sheep fed hay (80%) and concentrates (20%). Mean retention times of the particulate markers are in the order Cr-mord. > Cr-cell > 169Yb. Cr-EDTA gives more consistent results than PEG. Key words: Particulate markers, fluid markers, mean retention time, rumen, whole tract, feeding frequency, hay, sheep
