Practical Methane Cuts Gain Ground On Dairy Farms

Australian dairy farmers are increasingly adopting practical methane reduction tools as pressure grows to lower livestock emissions while maintaining profitability. Rather than waiting for future technologies, the industry is focusing on feed additives and farm management systems that can be integrated into existing dairy operations with minimal disruption. Feed additives have emerged as the leading solution. Products based on red seaweed, essential oils and synthetic compounds such as 3-NOP are being used to reduce methane produced during digestion. Research in Australia has shown these technologies can cut methane emissions by anywhere from 25% to more than 90%, depending on the additive, feeding system and ration used. The challenge for dairy producers is turning promising science into a workable on-farm strategy. Grazing systems dominate Australian milk production, making it harder to deliver feed additives consistently than in feedlot systems. For that reason, companies and ...
