Minerva Foods and Rumin8 announced the results of a study demonstrating significant reductions in methane emissions from cattle alongside improved feed efficiency. The research was conducted in partnership with the University of São Paulo through the Luiz de Queiroz College of Agriculture (ESALQ/USP), one of Brazil's leading agricultural research institutions.
The 120-day study evaluated the impact of Rumin8's feed additive on enteric methane emissions and productive performance in Nellore cattle under conditions simulating commercial Brazilian feedlot operations. Animals receiving the additive in a total mixed ration (TMR) showed a 50.4% reduction in methane emissions and a statistically significant 5% improvement in feed conversion efficiency compared with cattle fed the same diet without the additive.
David Messina, CEO, Rumin8, said, "We were pleased to partner with Minerva and ESALQ/USP to assess Rumin8's ability to mitigate methane and its impact on animal performance in an environment that simulates a commercial Brazilian feedlot setting. Minerva and Rumin8 are both committed to reducing methane emissions from the agriculture and food sector, and it was excellent to have this work validated by one of Brazil's most respected academic institutions. The results of this study were significant and will form part of our data package as we move toward commercialisation in Brazil, home to the world's largest commercial cattle herd."
The study also found that methane intensity per kilogram of liveweight gain decreased from 77.2 g/kg to 39.6 g/kg when comparing cattle fed only a TMR with those receiving the additive.
In total, the trial achieved an estimated reduction of 29.8 tonnes of CO2 equivalent in greenhouse gas emissions, while also delivering productivity gains and lower feed consumption. Independent verification of these results is currently underway by companies specialising in agricultural carbon certification, including Athian and FoodChain ID.
"This study highlights the potential of innovation and collaboration between industry, science and technology to address one of the most pressing challenges on the livestock sector's climate agenda. Reducing methane emissions is a strategic priority for advancing more sustainable cattle production, and initiatives like this help accelerate solutions that combine productivity and environmental responsibility," said Minerva Foods spokesperson.
