Enteric Methane Emissions from Dairy–Beef Steers Supplemented with the Essential Oil Blend Agolin Ruminant

Animals, 2023
Agriculture is the largest source of methane globally, and enteric methane accounts for 32% of methane emissions globally. Dairy–beef is an increasingly important contributor to the beef industry.

Strategies to Mitigate Enteric Methane Emissions from Ruminant Animals

Journal of Microbiology and Biotechnology, 2022
Human activities account for approximately two-thirds of global methane emissions, wherein the livestock sector is the single massive methane emitter. Methane is a potent greenhouse gas of over 21 times the warming effect of carbon dioxide. In the rumen, methanogens produce methane as a by-product of anaerobic fermentation.

Relationship between residual feed intake and enteric methane emission in Nellore cattle

Revista Brasileira de Zootecnia, 2015
Feed intake and average daily gain (ADG) in Nellore cattle were determined to calculate residual feed intake in two performance tests: first during the growth phase (RFIgrowth) and then during a measurement of the methane emission phase (RFImet).

Screening macroalgae for mitigation of enteric methane in vitro

Scientific Reports, 2023
AbstractThis study investigated the effects of 67 species of macroalgae on methanogenesis and rumen fermentation in vitro. Specimens were analyzed for their effect on ruminal fermentation and microbial community profiles. Incubations were carried out in an automated gas production system for 24-h and macroalgae were tested at 2% (feed dry matter basis)

Factors influencing dietary tannin inclusion in dairy diets: A review [PDF]

Journal of Applied Veterinary Sciences
T The objective of this paper was to evaluate factors affecting tannin dietary inclusion on enteric methane emission (CH4) and performance in dairy cows. Dairy production contributes to the greenhouse effect as it naturally emits enteric CH4.

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 ...

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 ...

Feeding Strategies to Mitigate Enteric Methane Emission from Ruminants in Grassland Systems

Animals, 2022
Ruminants produce approximately 30% of total anthropogenic methane emissions globally. The objective of this manuscript was to review nutritional enteric methane abatement practices for ruminants that are applicable under grazing conditions.

Enteric methane mitigation by using seaweed Eucheuma cottonii

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Methane is one of greenhouse gasses cause global climate change. Sources of methane emitted by livestock are from enteric fermentation during feed digestion in the rumen of ruminant animals and from manure of ruminant and non ruminant. Methane enteric contributes the largest portion of total gas emitted by livestock.
