Effect of 3-nitrooxypropanol supplementation combined with 6-hour grazing on enteric methane emissions and milk production characteristics Open
Various studies have shown that 3-nitrooxypropanol (3-NOP) reduces methane emissions in dairy cows. Providing 3-NOP in a partial mixed ration or TMR is recommended to continuously expose the rumen to the additive. During grazing, there is …

Screening of and Mechanistic Insights Into the Enteric Methane Mitigation Potential of European Native and Non‐Native Forage Trees, Shrubs, and Herbs Using In Vitro Batch Culture Open
Enteric methane (CH 4 ) emissions from ruminant livestock must be mitigated to reduce their climate impact. Trees, shrubs, and herbs have gained attention for their nutritional value, climate resilience, and CH 4 reduction potential. This …

Feed additives for methane mitigation: Recommendations for testing enteric methane-mitigating feed additives in ruminant studies Open
There is a need for rigorous and scientifically-based testing standards for existing and new enteric methane mitigation technologies, including antimethanogenic feed additives (AMFA). The current review provides guidelines for conducting a…

Predicting CO2 production of lactating dairy cows from animal, dietary, and production traits using an international dataset Open
Automated measurements of the ratio of concentrations of methane and carbon dioxide, [CH4]:[CO2], in breath from individual animals (the so-called "sniffer technique") and estimated CO2 production can be us…

Integrating heterogeneous across-country data for proxy-based random forest prediction of enteric methane in dairy cattle Open
Direct measurements of methane (CH4) from individual animals are difficult and expensive. Predictions based on proxies for CH4 are a viable alternative. Most prediction models are based on multiple linear regressions …

Comparison of Methods to Measure Methane for Use in Genetic Evaluation of Dairy Cattle Open
Partners in Expert Working Group WG2 of the COST Action METHAGENE have used several methods for measuring methane output by individual dairy cattle under various environmental conditions. Methods included respiration chambers, the sulphur …

Evaluation of mathematical models to predict methane emissions from ruminants under different dietary mitigation strategies Open
This study evaluated the ability of published models to predict enteric methane (CH4) emissions from dairy cattle, beef cattle, sheep and dairy goat, using a large database (3183 individual animal data). Models for each animal subcategory …

Reducing enteric methane emissions from dairy cattle: Two ways to supplement 3-nitrooxypropanol Open
The aim of this work was to determine the effect of 3-nitrooxypropanol (3-NOP) on the enteric methane (CH4) emissions and performance of lactating dairy cows when mixed in with roughage or incorporated into a concentrate pellet.…

Symposium review: Uncertainties in enteric methane inventories, measurement techniques, and prediction models Open
Ruminant production systems are important contributors to anthropogenic methane (CH4) emissions, but there are large uncertainties in national and global livestock CH4 inventories. Sources of uncertainty in enteric CH…

Prediction of enteric methane production, yield, and intensity in dairy cattle using an intercontinental database Open
Enteric methane ( CH 4 ) production from cattle contributes to global greenhouse gas emissions. Measurement of enteric CH 4 is complex, expensive, and impractical at large scales; therefore, models are commonly used to predict CH 4 product…

Combining heterogeneous across-country data for prediction of enteric methane from proxies in dairy cattle Open
Large-scale measurement of enteric methane (CH4) from individual animals is a requisite for estimation of genetic parameters and prediction of breeding values. Direct measurement of individual CH4 emissions is logistically demanding and ex…

Predictions of methane emission levels and categories based on milk fatty acid profiles from dairy cows Open
Milk fatty acid (MFA) have already been used to model methane (CH4) emissions from dairy cows. However, the data sets used to develop these models covered limited variation in dietary conditions, reducing the robustness of the predictions.…
