A meta-analysis of 3-nitrooxypropanol effects on methane production and yield in beef cattle

This meta-analysis quantifies 3-NOP's effect on reducing methane production and yield in beef cattle, showing average reductions of 36.2% and 33.2%, with efficacy influenced by diet composition.

Red seaweed supplementation suppresses methanogenesis in the rumen, revealing potentially advantageous traits among hydrogenotrophic bacteria

This study investigates how Asparagopsis supplementation affects rumen microbiota, finding reduced methane production and changes in microbial gene expression and function.

A meta-analysis of effects of seaweed and other bromoform containing feed ingredients on methane production, yield, and intensity in cattle

This study evaluates the impact of bromoform-containing feed ingredients on methane emissions in cattle, finding significant reductions in methane production and yield with varying efficacy based on cattle type and diet.

Carbon footprint of South Dakota dairy production system and assessment of mitigation options

This study estimates the carbon footprint of South Dakota dairy production and identifies mitigation strategies to reduce greenhouse gas emissions.

Red seaweed (Asparagopsis taxiformis) supplementation reduces enteric methane by over 80 percent in beef steers

Supplementing beef steer diets with 0.25% or 0.5% Asparagopsis taxiformis for 147 days reduces enteric methane yield by up to 80% and improves feed efficiency without altering meat quality.

Evaluation of the Potential of Two Common Pacific Coast Macroalgae for Mitigating Methane Emissions from Ruminants

This study evaluates two Pacific Coast macroalgae for their ability to reduce methane emissions from ruminants in vitro, finding A. taxiformis significantly more effective than Z. farlowii.

Effect of the macroalgae Asparagopsis taxiformis on methane production and the rumen microbiome assemblage

This study evaluates the effect of Asparagopsis taxiformis on methane production and rumen microbiome in dairy cattle, finding a 95% reduction in methane with no negative impact on fermentation parameters.
