There's a lot of ongoing research around cattle and whether they can be sustainable. Distilled down, this research is comprised of three main areas, and here's the short run-down of each:
How They Graze
Cattle grazing practices are vital for environmental sustainability, with a focus on adaptive multi-paddock (AMP) grazing. This technique involves moving cattle frequently between small fenced-off areas, allowing for soil recovery and promoting ecosystem health. AMP grazing mimics the natural movements of wild grazing herds, enhancing soil fertility, carbon sequestration, and biodiversity. Research funded by McDonald’s and led by documenter Peter Byck has shown that AMP grazing can result in higher soil carbon and nitrogen levels, indicating healthier ecosystems and potentially more nutritious grazing for cattle.
Takeaway: Adaptive multi-paddock grazing is a sustainable practice that improves soil health, sequesters carbon, and supports ecosystem biodiversity.
What They Eat
In North America, cattle are often transitioned to feedlots for a high-starch, energy-rich diet to promote rapid weight gain, contrasting with the primarily grass-fed diets seen in countries like Brazil and Argentina. However, this diet contributes to significant methane emissions through enteric fermentation. To combat this, research into feed additives like Mootral’s garlic and citrus bioflavonoids mix, along with alternatives like lab-grown red seaweed, aims to reduce methane emissions significantly. While these innovations show promise in reducing environmental impact, achieving commercial scale remains a challenge.
Takeaway: Diverse feed additives are being developed to reduce methane emissions from cattle, offering environmental benefits while maintaining or improving farm economics.
Which Cattle They're Using
The selection of cattle breeds is increasingly influenced by climate adaptability and environmental impact. Scientists are exploring genome editing and other genetic advancements to develop heat-resistant cows that emit less methane. Innovations include the use of CRISPR technology to modify cows for better heat tolerance and methane reduction. While the application of genetically modified cattle in agriculture raises ethical and practical questions, these advancements could lead to more sustainable and climate-resilient cattle farming practices.
Takeaway: Advances in genetics and breeding are focused on creating cattle that are more resilient to climate change and have a reduced environmental footprint.
