Treating tropical grass with fibrolytic enzymes from the fungus Trichoderma reesei: Effects on animal performance, digestibility and enteric methane emissions of growing lambs
(2022-04-01)
Food security and climate change concerns are pressing livestock production industry to seek sustainable practices to increase productivity while reducing the intensity of enteric methane (CH4) emissions. In this scenario, ...
Strategies for reducing methane emissions from ruminants
(2011)
There is irrefutable evidence that human activities are affecting the global climate through the production of Green House Gases (GHG) of which methane (CH4) has a high warming potential. Enteric fermentation and manure ...
Tropical tanniniferous legumes used as an option to mitigate sheep enteric methane emission
(Springer, 2013-03-01)
This study presents the first results from Brazil using SF6 tracer technique adapted from cattle to evaluate the capability of condensed tannin (CT) present in three tropical legume forages, Leucaena leucocephala (LEU), ...
Prediction of enteric methane production, yield, and intensity in dairy cattle using an intercontinental database
(2018)
Enteric methane (CH4) production from cattle contributes to global greenhouse gas emissions. Measurement of enteric CH4 is complex, expensive, and impractical at large scales; therefore, models are commonly used to predict ...
Are dairy cows with a more reactive temperament less efficient in energetic metabolism and do they produce more enteric methane?
(2021-06-01)
It remains unknown whether dairy cows with more reactive temperament produce more enteric methane (CH4) and are less bioenergetically efficient than the calmer ones. The objectives of this study were (a) to evaluate the ...
Effects of pregrazing herbage mass in late spring on enteric methane emissions, dry matter intake, and milk production of dairy cows
(CIENCIAS, 2016)
Few studies have examined the effects of fresh forage quality on enteric methane (CH4) emissions of dairy cows under grazing conditions. The aim of the current study was to evaluate the effects of 2 contrasting forage ...
Methane emissions from Nellore bulls on pasture fed two levels of starch-based supplement with or without a source of oil
(2018-06-04)
Methane emissions (CH4) from enteric fermentation represent an energy loss to the animal ranging from 2% to 12% of gross energy (GE) intake therefore, the challenge is to develop diets and handling strategies to mitigate ...
Greenhouse gases inventory and carbon balance of two dairy systems obtained from two methane-estimation methods
(Science of The Total Environment, 2018)
