Do bison produce less methane than beef cows?

    I think it depends on what the animals are being fed or are eating on their own. A 1998 Canadian study found that bison turned 6.6% of their food intake (pelleted alfalfa) into methane, which was more than wapiti and deer species. The authors note that the percentage methane produced by these bison is similar to that of beef cows, which turned 5.9% of the pelleted alfalfa into methane. Based on this food source, bison produced slightly more methane than beef cows. However, other Canadian researchers have developed a food formula to reduce beef cow methane emissions by up to 25%. See the second article below for more details.
