title: [Studies on the determination of the part of bacterial nitrogen in relation to total nitrogen content in the duodenum of cows].
abstract: A method for estimation of content of bacterial nitrogen in duodenal intestine was described. The method of HUTTON et al. (1971) in modificated form for the own research was the best method. In two trials roughage (chopped dried forage) and ground corn were given to cows with duodenal bridge fistula in different order (90 min-intervall). Portion of bacterial nitrogen to total nitrogen was 72.5% (corn leads to roughage) and 64.7% (roughage leads to corn).
