C-Lock Inc. Research Spotlight: GreenFeed is Critical for Measuring Emissions in Grazing Cattle. The recent study from Ireland by Starsmore et al. (2024) investigated factors affecting enteric methane (CH?) emissions in grazing dairy cows using the GreenFeed monitoring system. Results indicated that enteric methane production is influenced by energy-corrected milk yield, metabolic liveweight, milk urea concentration, and body condition score, with these factors explaining 47% of the variation in emissions. The findings suggest that selecting for lower-emitting cows may impact milk production and profitability, highlighting the need for balanced breeding strategies.

C-Lock Inc. Research Spotlight: Synthetic Bromoform Drastically Reduces Methane Emissions The recent study by Kelly et al. (2025) evaluates the effectiveness of a synthetic bromoform-based feed additive (CHBr?) delivered using either Rumin8 powder or Rumin8 oil. The findings revealed that Rumin8 oil reduced methane emissions by approximately 95%, while the powder formulation showed no significant effect. Importantly, neither treatment negatively impacted dry matter intake (DMI), average daily gain (ADG), or feed conversion rate (FCR). This research is the first in vivo study to evaluate synthetic CHBr? for methane reduction in cattle, demonstrating its potential for commercial use. Future research should explore long-term effects, optimal dosing, and microbiome adaptations to ensure its effectiveness and safety over time. Read the full article here https://bit.ly/3R6469F.

A recent study explores the innovative use of exhalomics as a noninvasive method to assess rumen fermentation in dairy cows, proposing that exhaled-breath metabolomics could potentially replace traditional rumen sampling methods. Islam et al. (2024) used GreenFeed to collect exhalome samples 8 times over three consecutive days, representing every 3 h of a 24-h period. Results showed strong correlations between exhaled and ruminal volatile fatty acid profiles (r > 0.74). This research is particularly significant for those in the dairy and beef industries looking to enhance animal welfare and streamline management practices. By leveraging GreenFeed, researchers can gather critical data on methane emissions and fermentation processes without the stress associated with traditional rumen sampling.
