Methane emitted from the livestock sector contributes to greenhouse gas emissions worldwide. Understanding the variability in enteric methane production related to diet is essential to decreasing uncertainty in greenhouse gas emission inventories and to identifying viable greenhouse gas reduction strategies. Our study focused on measuring methane in growing beef cattle fed corn- or barley-based diets typical of those fed to cattle in North American feedlots. The experiment was designed as a… 

Enteric methane emissions from growing beef cattle as affected by diet and level of intake

A study was conducted to determine whether enteric methane emissions from growing feedlot cattle fed backgrounding diets based on barley silage could be reduced through grain supplementation and the effects of feed intake on CH4 emissions.

The Effect of Manure from Cattle Fed Barley- vs. Corn-Based Diets on Greenhouse Gas Emissions Depends on Soil Type

Efforts to reduce greenhouse gas (GHG) emissions from cattle production have led to modifications of livestock diet composition aimed at reducing CH4 emissions from enteric fermentation. These diet

Effect of dietary fat supplementation on methane emissions from dairy cows fed wheat or corn.

It is concluded that the grain component in the basal diet does not affect the mitigating effects of dietary fat supplements on methane emissions and milk yield from cows fed diets containing either corn or wheat grains.

Methane emissions from beef cattle: effects of fumaric acid, essential oil, and canola oil.

It is demonstrated that canola oil can be used to reduce methane losses from cattle, but animal performance may be compromised due to lower feed intake and decreased fiber digestibility.

concentrate in the fattening phase of a beef production system Enteric methane production and greenhouse gases balance of diets differing in

The effects of three high-concentrate diets on enteric methane production, total tract digestibility, and rumen fermentations of beef cattle and the potential impacts of these feeding systems on the environment were assessed by life cycle assessment.

Adaptation responses in milk fat yield and methane emissions of dairy cows when wheat was included in their diet for 16 weeks.

The data indicate that cows do not all respond in the same way with some "adaptive" cows showing a marked increase in CH4 yield, milk fat concentration, and milk fat yield after wk 4, whereas in other "nonadaptive” cows, these metrics were persistently inhibited to 16 wk.

Comparison of Methane Production in Korean Native Cattle (Hanwoo) Fed Different Grain Sources

This study focused on comparison in methane production from growing Korean native steers fed different grain sources, finding that methane emission factor by maintenance energy requirement for the growing steers feeding barley based concentrate was higher than the steer fed corn based concentrate.

Methane emissions from beef cattle: Effects of monensin, sunflower oil, enzymes, yeast, and fumaric acid.

It is demonstrated that sunflower oil, ionophores, and possibly some yeast products can be used to decrease the GE lost as methane from cattle, but fiber digestibility is impaired with oil supplementation.

Methane emissions from cattle.

Knowing the factors that impact methane production can result in the development of mitigation strategies to reduce methane losses by cattle and implementation of these strategies should result in enhanced animal productivity and decreased contributions by cattle to the atmospheric methane budget.

Comparison of hull-less barley, barley, or corn for lactating cows: effects on extent of digestion and milk production.

Six lactating, cannulated Holstein cows were used in a double 3 x 3 Latin square design to compare the effects of hull-less barley with barley and corn on ruminal fermentation, rate of passage, flow

Barley- versus protein-supplemented corn-based diets for feedlot cattle evaluated using the NRC and CNCPS beef models

The NRC and CNCPS models predicted the substantially lower gain of cattle fed the corn diet with no protein supplementation, which was predicted to be lower than the actual gain.

Methane production by ruminants: its contribution to global warming

The most promising areas for future research for reducing methanogenesis are the development of new products/delivery systems for anti-methanogenic compounds or alternative electron acceptors in theRumen and reduction in protozoal numbers in the rumen.

Methane and carbon dioxide emissions from dairy cows in full lactation monitored over a six-month period.

Methane and CO2 emissions from a herd of 118 lactating cows were measured directly by continuous monitoring with an infrared gas analyzer from 24 gas sampling locations, and values were not corrected for gas emissions from stored manure.

This study showed that mathematical modelling is a valuable tool to evaluate the impact of a given dietary manipulation not only on methanogenesis but also on the metabolism of the whole rumen system.

Fibrolytic enzyme supplements for dairy cows in early lactation.

Investigating effects of exogenous fibrolytic enzyme supplementation on dry matter intake, milk production, and digestibility in multiparous lactating Holstein cows in early lactation found it has the potential to enhance milk yield and nutrient digestibility of cows inEarly lactation without changing feed intake.

It is suggested that the rumen ciliates, by modifying theRumen VFA proportions, are directly responsible for the increased CH4 production in faunated animals.
