Abstract
The objective of this study was to determine the effect of dietary nitrate (NO3) on methane emission and rumen fermentation parameters in Nelore x Guzera (Bos Indicus) beef cattle fed a sugarcane-based diet. The experiment was conducted at Instituto de Zootecnia, Nova Odessa, São Paulo State, Brazil. The study included sixteen steers weighing 283 ± 49 kg (mean ± SD), six rumen-fistulated and ten intact, in a cross-over design. The animals were blocked according to body weight and fistula, thereafter randomly allocated to either the control (1.2% urea in diet DM) or the nitrate (2.2% NO3 in diet DM) diet. The diets were iso-nitrogenous and consisted of sugarcane and concentrates (60:40 on DM basis), fed as a total mixed ration. Methane emission was measured using the sulphur hexafluoride (SF6) tracer technique. DMI was not affected (P=0.14) by addition of NO3 to the diet. The daily methane production per animal was reduced (P
