SUSTAINABILITY 88 FEED & ADDITIVE MAGAZINE February 2026 consistent efficacy, stability, palatability and ease of integration into existing farm operations. We have formulated our product Methane Tamer to stabilize the key components in Asparagopsis – especially bromoform - and to ensure cattle will eat the product as part of their daily rations. We started with cattle in feedlots, as humans control everything that cattle eat. Our product is designed so it can be easily mixed into daily rations. It can also be easy to control when fed to dairy cattle as part of their daily TMR. Our research has shown that Asparagopsis is palatable when dried and mixed with natural additives, such as molasses. We know that consumers do not want to buy food products – whether they be dairy or beef – if the cow has been fed chemicals or extracts. Farmers are also leaning towards feeding their cattle natural products that are chemical-free.” COMPANY-SPECIFIC SOLUTIONS AND TARGETED MECHANISMS Today, many companies have developed unique nutritional solutions targeting different biological processes for methane reduction. These solutions exert their effects through mechanisms such as rumen fermentation, hydrogen sink, microbial populations, and feed efficiency. Jason Jeong-Hoon Kim summarizes the approach of Cargill ANH, which integrates methane reduction within a framework of animal performance, health, and safety: “Cargill Animal Nutrition & Health (ANH) addresses methane from ruminants through a combination of direct nutritional solutions and indirect productivity-driven strategies, under our ruminant sustainability platform called ReaCH4ReductionTM. The platform aims to reduce both absolute emissions and methane intensity while safeguarding animal health, performance and farmer profitability. The primary direct methane-mitigation solution ANH developed with years of research is SilvAir™, a patented feed material solution designed to function as an alternative hydrogen sink in ruminants. In a recent meta-analysis published in the Journal of Dairy Science, SilvAir has been shown to reduce methane emissions by up to 20% without adverse impacts on animal performance. In addition, SilvAir™ provides nitrogen and available calcium to a cow’s diet. ANH also supports indirect methane-intensity reduction through advanced nutrition optimization. Solutions such as Dairy MAX™ and Beef MAX™ balance dietary protein fractions and energy supply to reduce waste losses, thereby lowering methane emissions per unit of milk and meat produced. Across all approaches, ANH applies a holistic framework that integrates methane reduction with animal performance, health and safety.
