How Enteric Methane is Produced by Cattle
About 3 to 12% of the energy consumed by ruminants (cattle and sheep) is converted to methane in the rumen (referred to as enteric methane) and released into the atmosphere. Adopting feeding strategies that will minimize the amount of energy, lost as methane, can improve feed conversion efficiency, improve animal productivity, and is good for the environment. Producers can reduce their herd's m...
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...
متن کاملClimate Clever Clovers: New Paradigm to Reduce the Environmental Footprint of Ruminants by Breeding Low Methanogenic Forages Utilizing Haplotype Variation
Mitigating methane production by ruminants is a significant challenge to global livestock production. This research offers a new paradigm to reduce methane emissions from ruminants by breeding climate-clever clovers. We demonstrate wide genetic diversity for the trait methanogenic potential in Australia's key pasture legume, subterranean clover (Trifolium subterraneum L.). In a bi-parental popu...
متن کاملNutritional strategies to mitigate greenhouse gases emission from livestock agriculture: a review
Received: 11/11/2013 Revised: 13/12/2013 Accepted: 15/12/2013 Abstract Methane is the second key greenhouse gas (GHG) and enteric fermentation in livestock is one of the largest sources of methane emission, producing 15-20 % of the total anthropogenic methane. Methane production by enteric fermentation in the rumen accounts for the 2-12% loss of gross energy and consequently influence performan...
متن کاملNitrate but not tea saponin feed additives decreased enteric methane emissions in nonlactating cows.
Tea saponin is considered a promising natural compound for reducing enteric methane emissions in ruminants. A trial was conducted to study the effect of this plant extract fed alone or in combination with nitrate on methane emissions, total tract digestive processes, and ruminal characteristics in cattle. The experiment was conducted as a 2 × 2 factorial design with 4 ruminally cannulated nonla...
