A wide range of different forages were either fed as the sole feed or supplemented with a fixed amount of concentrate and fed to dairy cows in four separate experiments. Rumen microbial AAN synthesis was calculated based on content of RNA in isolated rumen liquid associated bacteria and in duodenal chyme. Efficiency was calculated based on apparent total tract digested carbohydrates, apparent and true rumen digested OM and true rumen digested fermentable OM.
