Simple Summary Concerns about greenhouse gas (GHG) emissions from livestock and
dairy farms, as well as their connection to global warming and climate change, have grown …

Efforts to reduce the carbon footprint of milk production through selection and management
of low-emitting cows require accurate and large-scale measurements of methane (CH 4) …

A 1000-cow study across four European countries was undertaken to understand to what
extent ruminant microbiomes can be controlled by the host animal and to identify …

Selecting for lower methane (CH 4) emitting animals is one of the best approaches to reduce
CH 4 given that genetic progress is permanent and cumulative over generations. As genetic …

The aim of this review is to summarize the current knowledge of methane (CH4) production
from ruminants. The objectives are to identify the factors affecting CH4 production. Methane …

The objective of this study was to estimate heritability of enteric methane emissions from
dairy cattle. Methane (CH 4) and CO 2 were measured with a portable air-sampler and …

The objective of this study was to investigate whether measurement of methane emissions
by individual dairy cows during milking could provide a useful technique for monitoring on …

Life-cycle assessment (LCA) is the preferred methodology to assess carbon footprint per unit
of milk. The objective of this case study was to apply an LCA method to compare carbon …

Phenotypes have been reviewed to select for lower-emitting animals in order to decrease
the environmental footprint of dairy cattle products. This includes direct selection for breath …

Dairy production systems are often criticized as being major emitters of greenhouse gases
(GHG). In this context, the extension of the length of the productive life of dairy cows is …
