Greenhouse gases (GHGs) are the primary drivers of global warming and climate change, with carbon dioxide (CO2) and methane (CH4) being the two most significant GHGs. In ruminants, enteric fermentation is responsible for 80–90% of GHG emissions from livestock. In this study, we investigated the effects of Polygain™ (PG), a polyphenolic extract from sugarcane, on the enteric CH4 emission from Holstein Friesian weaned calves kept at the University of Melbourne Dookie Dairy Farm. Our findings indicate that PG supplementation reduced their average methane emission per day and did not adversely affect the growth and development of experimental calves.
