The efficiency of polyethylenoglicol (PEG) and Co-EDTA was evaluated on the estimate of the main parameters that characterize the liquid phase’s kinetics of Holstein x Zebu cows’ rumen. Significant differences were not observed (P>0,05) among the markers for estimates of ruminal volume (l), passage rate (l/h), retention time (h), outflow rate (l/h) and recycling rate (cycles/d). However, Co-EDTA was the most suitable marker and presented more stability than PEG did. When the spectrophotometry (Co-EDTA methodology of analysis) became impossible, the marker PEG can be a cheap alternative and it supplies satisfactory results, since, the meticulousness of the turbidimetric technique is respected.KEYWORDS: Co-EDTA, liquid phase, outflow rate, polyethylenoglicol, ruminal volume.
