The Meet Your Herdmates Sodcast

The Meet Your Herdmates Sodcast

There are many people who know something about ruminant animal agriculture and the essential role it plays in meeting the needs of today’s world and the world of 2050. Their expertise may be in some aspect of soil, plant, animal or human health. Or it may be in topics related to environmental stewardship, public policy, or sustainable development. The Ruminati is my attempt to assemble them and introduce them to each other. The goal of this sodcast (see what I did there?) is to make their information more widely known. Welcome to the herd!
