Resumo: 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.

Não foi observada diferença significativa (P>0,05) entre os dois indicadores para os parâmetros volume ruminal (l), taxa de passagem (l/h), tempo de retenção (h), taxa de fluxo (l/h) e taxa de reciclagem (ciclos/d). Entretanto, o Co-EDTA mostrou ser o indicador mais adequado, por apresentar maior estabilidade que o PEG. Em contrapartida, na impossibilidade de realização da espectrofotometria (metodologia de análise do Co-EDTA), o PEG surge como alternativa barata e que fornece resultados satisfatórios, desde que seja respeitado o caráter minucioso da técnica turbidimétrica. PALAVRAS-CHAVES: Co-EDTA, fase líquida, polietilenoglicol, taxa de passagem, volume ruminal.
