Cluster analysis based on unweighted pair group method with arithmetic mean of polymerase chain reaction denaturing gradient gel electrophoresis profiles showing the effect of C, S5 and S9 diets on total bacteria (A) and the Butirivibrio group (B) in rumen liquor collected at 0, 6, 12 and 24 h. C = control feed; S5 = treatment with 50 g/kg of stoned olive pomace; S9 = treatment with 90 g/kg of stoned olive pomace. Scale relates to percent similarity.
