Abstract:
:Alkaline phosphatase (APase) was present in the bovine rumen in both cell-free and cell-associated states and levels of the enzyme varied with dietary regime. Reaction product deposition showed that the enzyme was associated with the mixed bacterial population. No enzyme was observed to be associated with protozoa. Trace activity of APase was also detected in the saliva. The presence of large amounts of APase in cell-free rumen fluid of cattle fed fine concentrate feed is believed to be due, in part, to the breakage of bacterial cells that occurs in the rumen.
