A recent interview by Caroline Stocks, a UK journalist who writes about food, agriculture and the environment, of air quality expert Frank Mitloehner, a professor of animal science at the University of California at Davis, calls into question how responsible cows are for climate change.
By mixing compounds from garlic, citrus and other additives into a pellet that’s mixed with a cow’s regular diet, the start-up [Mootral] has surprised scientists by significantly and consistently cutting the toxic output [methane] of animals.
The addition of 3-Nitrooxypropanol to the feed of dairy cows reduced their enteric methane emissions by about 25% in a recently published study—one in a series of Penn State studies of the investigational substance in the United States—which might be an early step toward it being approved for use in this country.
A new scientific article from the Feed the Future Innovation Lab for Livestock Systems has four big messages: (1) Meat, offal, milk, eggs and fish are vital to—and missing from—the diets of nearly 800 million people. (2) ‘Animal-sourced foods’ are the best sources of high-quality nutrient-rich food for toddlers 6–23-months old. (3) The harms caused by livestock and animal-sourced foods to human and planetary health are overstated. (4) Sustainable development must address the needs of the poorest and most vulnerable people in the world.
Key partners come together to develop robust systems for measurement, reporting and verification of emissions from Ethiopia’s livestock sector.
