Enteric methane emissions and mitigation strategies within pasture-based dairy systems
Abstract
Baseline methane emissions from lactating cows grazing high-quality pasture may be lower than currently predicted by on-farm calculators and national inventories. Several mitigation strategies are being explored, including technological interventions, genetic selection, and nutritional approaches. However, the methane response to these strategies will depend on both the baseline emissions of the animals and the mode of action of the mitigation. Improving our understanding of baseline methane emissions, the factors that drive seasonal variation, and the responses to different mitigation strategies will support a more targeted approach to reducing methane emissions across the grazing season. Highlights• Baseline methane from pasture-based systems may be lower than inventory estimates.
• Baseline methane depends on cow intake levels and the nutritive value of the diet.
• Mitigation responses depend on the baseline methane and mode of action.
• Currently, there are no scalable or viable mitigations for pasture-based systems.
