Efeito do ambiente nas variáveis fisiológicas e na emissão de metano associado à produção e à perda de calor em ovinos
(Universidade Estadual Paulista (Unesp), 2013-08-14)
A agropecuária é uma das fontes que mais contribui com a emissão de metano (CH4) e dióxido de carbono (CO2), os quais participam do processo natural de efeito estufa. A pecuária por meio da fermentação entérica é uma ...
How do animal performance and methane emissions vary with forage management intensification and supplementation?
(2020-06-01)
Context: Yields from Brazilian beef-production systems do not always match the expected potential of a forage-based beef-production system. This efficiency is dependent on adjustments of grazing intensity and supplement ...
Effects of dietary concentrate supplementation on enteric methane emissions and performance of late lactation dairy cows
(INST INVESTIGACIONES AGROPECUARIAS, 2018)
Dietary supplementation with concentrates is regarded as an effective strategy to decrease the intensity of methane (CH4) emissions, although it has rarely been evaluated in late lactation dairy cows. The aim of the present ...
Does a reduction in dietary crude protein content affect performance, nutrient requirements, nitrogen losses, and methane emissions in finishing Nellore bulls?
(Agriculture, Ecosystems & Environment, 2018)
Prediction of enteric methane production, yield and intensity of beef cattle using an intercontinental database
(2019-11-01)
Enteric methane (CH4) production attributable to beef cattle contributes to global greenhouse gas emissions. Reliably estimating this contribution requires extensive CH4 emission data from beef cattle under different ...
