Abstract
Summary: A method is described for the determination of rumen volume using Cr-EDTA colour measurement in a spectrophotometer at 550 nm. The results of several determinations of rumen volume comparing this method with Cr-determination as chromate and polyethylene glycol as markers gave similar values with differences ranging from 1 to 14% with an average of 6%. Direct measurements through evacuating rumen contents gave values 20·68% higher than those estimated by the colour method. The values were similar when corrected for dry matter.This publication has 6 references indexed in Scilit:
