KEYWORDS
ABSTRACT
Particle passage kinetics in dairy cows was assessed using acid detergent fibre (ADF) associated 15N as an internal marker and chromium (Cr) mordanted grass silage, ytterbium (Yb) labelled grass silage and dysprosium (Dy) labelled faecal particles as external markers. Kinetic parameters were estimated using two-compartment models assuming gamma time-dependent (G3) passage rate in the first compartment and age-independent (G1) in the second compartment. Parameter estimates were consistent between ADF-15N and Cr, but for Yb and Dy the total mean retention time and retention time in the age-independent compartment was shorter.
