Abstract:The objective of this work was to compare nitrous oxide (N2O) emissions from urine and manure of Nellore and crossbred (Nellore x Angus) cattle finished in feedlot. Twenty Nellore and 20 crossbred bulls were fed a diet consisting of 75% concentrate and 25% roughage. Excreta were applied to the pens after 43 days of confinement, when N2O monitoring started through static chambers. The data were subjected to the analysis of variance, and averages were compared by Tukey’s test. The N2O fluxes from urine and manur… Show more
