“…Let us take Peru as an example. The share of livestock in the countries' GHG emissions is reported to be 14.5%, of which 64% stem from enteric fermentation and manure emissions from ruminants [100]. Peru is home to 27% of the world's llama population, 0.75 million animals, and a study using tannins in the diet of these animals found that methane production could be reduced by 30% in llamas [100].…”

Strategies to Mitigate Enteric Methane Emissions in Ruminants: A Review

et al. 2022

Methane is the main greenhouse gas (GHG) emitted by ruminants. Mitigation strategies are required to alleviate this negative environmental impact while maintaining productivity and ruminants’ health. To date, numerous methane mitigation strategies have been investigated, reported and suggested by scientists to the livestock industry. In this review, the authors will focus on the commonly practiced and available techniques expanding the knowledge of the reader on the advances of methane mitigation strategies with a focus on the recent literature. Furthermore, the authors will attempt to discuss the drawbacks of the strategies in terms of animal health and performance reduction as well as the concept of feed and energy loss, adding an economic perspective to methane emission mitigation which is in the farmers’ direct interest. As a whole, many factors are effective in reducing undesired methane production, but this is definitely a complex challenge. Conclusively, further research is required to offer effective and efficient methane production mitigation solutions in ruminants worldwide, thus positively contributing to climate change.

“…Moreover, this implementation serves as a preventive measure against boar taint by minimizing intestinal skatole production . The supplementation of HT in the diet of pigs, chickens, and bulls has been shown to accelerate their growth rate and improve gastrointestinal well-being, as evidenced by several studies. − Additionally, it contributes to a reduction in enteric methane emissions in llamas and bulls …”

Castanea sativa wood is a rich source of hydrolyzable tannins, known for their diverse bioactivities. To investigate these bioactive properties further, it is crucial to isolate and characterize hydrophilic compounds effectively. To address this issue, we developed a centrifugal partition chromatography (CPC) method and applied it to an aqueous C. sativa wood extract. We determined the partition coefficients (K D ) of the six major compounds using four butanol-/ water-based biphasic solvent systems. Initially, we utilized the nbutanol/propanol/water (3:1:4, v/v/v) systems for the first fractionation step. Subsequently, we employed the water/methyl tert-butyl ether/butanol/acetone (8:5:3:4, v/v/v/v) system to fractionate moderately and highly hydrophilic fractions. We calculated the K D values for major compounds of the most hydrophilic fractions using the butanol/ethanol/water (4:1:5, v/v/v) and butanol/isopropanol/water (2:1:3, v/v/v) systems. In total, we isolated 23 compounds through a combination of CPC, size exclusion chromatography, and preparative HPLC. Among these compounds, six have never been previously described. We characterized them by 1D and 2D NMR experiments and high-resolution mass spectroscopy acquisitions.
