Long-Term encapsulated nitrate supplementation modulates rumen microbial diversity and rumen fermentation to reduce methane emission in grazing steers. This study investigated the long-term effects (13 months) of encapsulated nitrate supplementation (ENS) on enteric methane emissions, rumen fermentation parameters, ruminal bacteria, and diversity of... ...

Methane emissions and growth performance of young Nellore bulls fed crude glycerine- v. fibre-based energy ingredients in low or high concentrate diets. A total of 70 Nellore bulls (18 ± 3 months of age) were used to determine the effects of crude glycerine (CG) replacing starch- v. fibre-based energy ingredients in low (LC; 0·40 concentrate) or high... ...

Performance and methane emissions of Nellore steers grazing tropical pasture supplemented with lipid sources. Abstract: The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH4 emission of Nellore steers grazing Brachiaria brizantha cv. X... ... Repositório: BDPA Ano de publicação: 2016
Greenhouse gas mitigation and offset options for beef cattle production under contrasting pasture management systems in Brazil. This study estimates the GHG balance (emissions and sinks) related to the beef cattle production in three contrasting production scenarios on Brachiaria pasture in Brazil: 1) Degraded pasture (DP), 2)... ...
