Summary

Two consecutive trials were conducted to investigate the effects of glucosinolates (GLS) in rapeseed cake (RSC) on nitrogen (N) metabolism and urine nitrous oxide (N<sub>2</sub>O) emissions in steers. In trial 1, 8 steers and 4 levels of RSC, i.e. 0, 2.7%, 5.4% and 8.0% dry matter (DM) (0, 6.0, 12.1, 18.1 μmol GLS/g DM) were allocated in a replicated 4 × 4 Latin square. In trial 2, the static incubation technique was used for measuring the N<sub>2</sub>O emissions of the urine samples collected from trial 1. The results of trial 1 indicated that dietary inclusion of RSC decreased the digested N and increased the fecal N excretion (<i>P</i> < 0.01), whereas it did not affect the urinary N excretion, total N excretion and N retention (<i>P</i> > 0.10). Dietary inclusion of RSC decreased the
