Seaweed Might Help Cows Go Green

Science Friday

When it comes to the bodies of humans and animals, there are a few functions that we’re usually discouraged from talking about. Specifically, the ones that involve releasing gas. (Yep, burps and farts.) But if you’re a cow, there’s a lot of scientific work that goes into analyzing what’s coming out in the gas you release. That’s because the cattle industry is one of the largest producers of methane gas, a huge contributor to global warming.

Some scientists are experimenting with feeding cows new things, to try to limit their methane output from the inside. New research shows a very promising result: By feeding beef cattle just a few ounces of dried seaweed per day, methane emissions from the cows went down as much as 82 percent.

Ira Flatow talks to the lead author of that paper, Ermias Kebreab, associate dean and professor of animal science at the University of California, Davis about how seaweed inhibits methane production in cows. They’re also joined by Albert Straus, founder and CEO of Straus Family Creamery in Marshall, California, who will be testing the seaweed diet on his cows this summer.
