"This method paves the way to make a seaweed supplement easily available to grazing animals," said Professor Ermias Kebreab, senior author of the study. This innovation could simplify the incorporation of eco-friendly practices for ranchers while maintaining cattle health and wellbeing.
"Previous studies have shown that livestock account for 14.5 per cent of global greenhouse gas emissions. And the largest portion comes from methane that cattle release when they fart and burp." This emphasizes the significant environmental impact that cattle have and justifies the need for effective interventions like seaweed.
"For the 10-week experiment...an analysis of the cows' flatulence revealed that the cows who consumed the seaweed supplement produced 40 per cent less methane than those who did not." This demonstrates a tangible, measurable benefit of the seaweed supplement.
"Grazing cattle...produce more methane than feedlot cattle or dairy cows. That's because they eat more fibre from grass." This insight highlights the challenge presented by grazing practices and the unique potential of targeting them with a seaweed solution.
