This study, conducted on a commercial dairy farm using robotic milking system in Victoria, Australia, examined the effects of Polygain™ (The Product Makers Australia), polyphenol-rich sugarcane feed material (PRSFM), CH4 emissions grazing cattle an inverse-dispersion model (IDM) combined with open-path laser techniques. Thirty lactating Holstein Friesian cows (aged 2-5 years average body weight 663 kg and daily milk production 28.9 kg) were divided into two dietary treatment groups fifteen each. Before measurement, PRSFM (0.25%) was supplemented for 3 weeks as adaptation period mixed pellet group. Over 2-week measurement period, (MP) 495 ± 12 377 (mean standard error) g CH4/animal/day control groups, respectively. Methane intensity (MI) 17.04 13.01 CH4/animal/kg milk/day On average, Polygain supplementation reduced MP MI by 24%. potential reduction extrapolated across Australia contributes to 2.63% national agricultural emissions. study underscores mitigation cattle.
