Description
Summary:	The objectives were to evaluate effects of phenolic acid content and composition on the digestibility of six meadow hays from Northern Portugal. Digestibility was assessed by gas production, in vitro and in situ degradation methods. Four cows fed diets at energy maintenance were used for in situ incubations and to provide rumen fluid for in vitro incubations. There were no relationships between phenolic acid concentrations and other cell wall components. The dry matter (DM) potential degradation (a + b) was positively related to the etherified fractions of ferulic acid (FAeth, P=0.012) and p-coumaric acid (PCAeth, P
