Can nutritional grouping lower feed costs and enteric methane when diets are optimized with modest ingredient changes?

JDS Communications
Nutritional grouping (NG), where cows are fed in groups based on similar nutrient requirements, has been used as a strategy to improve the precision of nutrition delivery and thus economic returns.

Estimating methane emissions from manure: a suitable case for treatment?

Environmental Research: Food Systems
Methane from livestock is a significant source of greenhouse gas emissions. Under the UN Framework Convention on Climate Change (UNFCCC), Annex I countries’ National Inventories report emissions from cattle as enteric or from manure management at ratios ...

Scaling up Seaweed Production for Enteric Methane Reduction: A Systematic Literature Review on Environmental and Ozone Impacts in the Case of Asparagopsis Macroalgae

Methane
Methane, a potent greenhouse gas, has a global warming potential over 84 times greater than carbon dioxide over its relevant lifespan. Current atmospheric methane concentrations are at a record high, significantly contributing to near-term climate ...

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.

Evaluation of models of enteric methane emissions in finishing steers

animal
Accurate estimation of enteric CH4 emissions (i.e., MJ or g of CH4/ day) in the ruminant sector is necessary for properly determining greenhouse gas emissions and developing measuring, reporting, and verification programs. However, measuring enteric CH4 emissions under commercial conditions presents challenges due to technical and economic constraints.

Variability in Enteric Methane Emissions among Dairy Cows during Lactation

Animals, 2022
The aim of this study was to investigate variability in enteric CH4 emission rate and emissions per unit of milk across lactations among dairy cows on commercial farms in the UK. A total of 105,701 CH4 spot measurements were obtained from 2206 mostly Holstein-Friesian cows on 18 dairy farms using robotic milking stations.

Reduced‐Graphene Oxide Nanofiltration Membranes Intercalated by Conjugated Polyaromatics: Towards High Monovalent Salt Rejections

Advanced Science, EarlyView.
We demonstrate the fabrication of a series of reduced‐GO nanofiltration membranes containing intercalated polyaromatic conjugated molecules of different structural classes. These tuned‐nanochannel membranes perform “deep nanofiltration” with remarkably high monovalent salt rejections and near‐total divalent salt rejections in a large concentration ...
