Reducing methane emissions in ruminants: is it an achievable goal?
Decreasing methane emissions and, more generally, decreasing the environmental footprint of ruminants is one pressing challenge facing the ruminant production sector. Notwithstanding, because of the intricate relationships existing between the efficiency of feed fermentation in the rumen and methanogenesis, mitigation options have to be evaluated not just in terms of their effect on methane or ...
متن کاملOpportunities and challenges in the use of the Laser Methane Detector to monitor enteric methane emissions from ruminants.
The objective of this review was to examine the application and relative efficiency of the proprietary hand-held Laser Methane Detector (LMD) in livestock production, with a focus on opportunities and challenges in different production systems. The LMD is based on IR absorption spectroscopy, uses a semiconductor laser as a collimated excitation source and uses the second harmonic detection of w...
متن کاملRecent Advances in Measurement and Dietary Mitigation of Enteric Methane Emissions in Ruminants
Methane (CH4) emission, which is mainly produced during normal fermentation of feeds by the rumen microorganisms, represents a major contributor to the greenhouse gas (GHG) emissions. Several enteric CH4 mitigation technologies have been explored recently. A number of new techniques have also been developed and existing techniques have been improved in order to evaluate CH4 mitigation technolog...
متن کاملCan Plant Saponins Lower Methane Emissions Without Hampering The Nutrient Digestibility of Ruminants?
Plant saponins have been used as additives to mitigate methane emissions originated from enteric fermentation of ruminant animals. Most of the studies however were based on in vitro techniques, and only limited studies were directly conducted on the animals. Inconsistencies of saponin effects on methane emissions have been previously observed, which might be related to their levels in rations. ...
متن کاملAnimal board invited review: genetic possibilities to reduce enteric methane emissions from ruminants
Measuring and mitigating methane (CH4) emissions from livestock is of increasing importance for the environment and for policy making. Potentially, the most sustainable way of reducing enteric CH4 emission from ruminants is through the estimation of genomic breeding values to facilitate genetic selection. There is potential for adopting genetic selection and in the future genomic selection, for...
