in both experiments the rates of bacterial crude protein ( n x 6.25 ) synthesis in the rumen , estimated using alpha , epsilon-diaminopimelic acid as a marker , were low , 142 and 161 g crude protein/kg organic matter apparently digested in the rumen for the spring silage and the spring silage and barley diets respectively , and 68 and 103 g crude protein/kg organic matter apparently digested in the rumen for the early-cut autumn silage and the late-cut autumn silage respectively .
