Variation in carbon footprint of milk due to management differences between Swedish dairy farms [PDF]

, 2011
To identify mitigation options to reduce greenhouse gas (GHG) emissions from milk production (i.e. the carbon footprint (CF) of milk), this study examined the variation in GHG emissions among dairy farms using data from previous CF studies on Swedish ...

Quantitative analysis of ruminal methanogenic microbial populations in beef cattle divergent in phenotypic residual feed intake (RFI) offered contrasting diets [PDF]

, 2014
peer-reviewedBackground Methane (CH4) emissions in cattle are an undesirable end product of rumen methanogenic fermentative activity as they are associated not only with negative environmental impacts but also with reduced host feed ...

Quantifying sources of methane using light alkanes in the Los Angeles basin, California [PDF]

, 2013
Methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and C2-C5 alkanes were measured throughout the Los Angeles (L.A.) basin in May and June 2010. We use these data to show that the emission ratios of CH4/CO and CH4/CO2 in the L.A. basin are larger

Canola Meal versus Soybean Meal as Protein Supplements in the Diets of Lactating Dairy Cows Affects the Greenhouse Gas Intensity of Milk

Animals, 2021
Soybean meal (SBM) and canola meal (CM) are protein supplements used in lactating dairy cow diets and, recently, an enteric methane-mitigating effect (i.e., lower Ym value) was reported for CM.

Emission intensities by Holstein and Holstein x Jersey crossbreed lactating cows in two Brazilian. [PDF]

, 2020
In recent years the concern with methane (CH4) emission by enteric fermentation has become indispensable for dairy production systems. The aim of this study was to evaluate CH4 emissions from pure Holstein (HOL) and 1/2Jersey 1/2HIn recent years the ...

Enteric methane emission of the Dutch dairy herd : Average and variation of enteric methane emission among the Dutch dairy herd

, 2020
The Netherlands aims to reduce greenhouse gas emissions by 49% in 2030 compared to 1990. In order to achieve this goal the dairy sector needs to reduce methane (CH4) emissions by 1.0 megaton CO2-equivalents compared to 2017. Approximately 80% of the CH4 emission of the dairy sector originates from enteric CH4.

A comparison of the economic value for enteric methane emissions with other biological traits associated with dairy cows [PDF]

This is the first study to derive the economic value of enteric methane produced by a ruminant animal. There is considerable interest globally in selecting for low methane-emitting ruminant livestock, as methane is a potent greenhouse gas.

Review: Strategies for enteric methane mitigation in cattle fed tropical forages

Animal, 2020
Methane (CH4) is a greenhouse gas (GHG) produced and released by eructation to the atmosphere in large volumes by ruminants. Enteric CH4 contributes significantly to global GHG emissions arising from animal agriculture.

Effect of dried leaves of Leucaena leucocephala on rumen fermentation, rumen microbial population, and enteric methane production in crossbred heifers [PDF]

, 2020
The effects of dietary inclusion of dried Leucaena leucocephala leaves (DLL) on nutrient digestibility, fermentation parameters, microbial rumen population, and production of enteric methane (CH4) in crossbred heifers were evaluated.

Phenotypic association among performance, feed efficiency and methane emission traits in Nellore cattle.

PLoS ONE, 2021
Enteric methane (CH4) emissions are a natural process in ruminants and can result in up to 12% of energy losses. Hence, decreasing enteric CH4 production constitutes an important step towards improving the feed efficiency of Brazilian cattle herds.
