Review: Enteric Methane Emissions Across Physiological Stages and Dietary NDF/NFC Ratios in Holstein Dairy Cattle—Implications for China’s Carbon Mitigation [PDF]

Animals
Dairy cattle are a substantial contributor to global agricultural greenhouse gas emissions, primarily producing enteric methane through the ruminal anaerobic fermentation of dietary fiber.

Ozone Decreased Enteric Methane Production by 20% in an in vitro Rumen Fermentation System [PDF]

Frontiers in Microbiology, 2020
Ozone (O3) is volatile, highly oxidative, and has theoretical potential to reduce ruminant enteric methanogenesis by interactions between archaea and bacteria, and substrate and oxygen.

Quantifying Greenhouse Gas Emissions and Carbon Footprint of Sheep Production Using the IPCC Tier 2 Approach [PDF]

Animals
Livestock production significantly contributes to greenhouse gas (GHG) emissions, particularly methane (CH4) and nitrous oxide (N2O) originating from enteric fermentation and manure management.

Development of methane emission factors for enteric fermentation in cattle from Benin using IPCC Tier 2 methodology

Animal, 2015
The objective of this study was to develop emission factors (EF) for methane (CH4) emissions from enteric fermentation in cattle native to Benin. Information on livestock characteristics and diet practices specific to the Benin cattle population were ...

Methane mitigation and ruminal fermentation changes in cows fed cottonseed and vitamin E

Scientia Agricola, 2020
: Inherently, ruminant production of methane (CH4), a greenhouse gas (GHG), causes animal energy losses. Cottonseed is a lipid source and is used sometimes to enhance energy density in cattle diets. It also can mitigate enteric CH4.

Short communication: Impact of the intensity of milk production on ammonia and greenhouse gas emissions in Portuguese cattle farms

Spanish Journal of Agricultural Research, 2015
The aim of this study was evaluate the relationship between the intensity of milk production for a wide range of Portuguese commercial cattle farms and NH3 and greenhouse gas (GHG) emissions from manure management and enteric fermentation.
