Abstract
Potentially digestible fibre leaves the rumen either by enzymatic breakdown or by passage to the lower tract. The digestibility of potentially digestible fibre is a function of the rate at which fibre is digested and its retention time in the rumen. The procedures used for estimating the rate of fibre digestion (kd) and the rate of passage of feed particles (kp) are extremely variable. The estimates for kdand kpderived by using different procedures can have a large effect on the fibre digestibility calculated from kinetic parameters of fibre. The objective of the present study was to evaluate the different methods in estimating the kinetic parameters of mathematical models that will describe cell wall digestion in the rumen.
