Ken Elliott runs a hemp oilseed and fiber processing facility in Fort Benton, Montana. His company, IND Hemp, grinds up the stalky plant so that it can be used for a variety of purposes, such as snacks, grain, insulation and paper. Some 20 truckloads of spent biomass lie in heaps on his property.

Elliott estimates he could make a couple million dollars if he sold this leftover stuff as livestock feed. Hemp seedcake would make a great substitute for alfalfa – rich in fatty acids, proteins and fiber. His cattle rancher buddies are hit hard by the soaring costs of hay and would love to get their hands on this alternative. One buffalo herder wanted to buy the whole lot.

But Elliot can’t sell to them. He can’t even give it away for free. That’s because when the 2018 Farm Bill took hemp off the list of controlled substances, hemp as commercial livestock feed was not approved.

The Food and Drug Administration (FDA) has approved hempseed and its meal and oil for human consumption. A variety of hemp snacks for pets are allowed on the market, because they don’t constitute the main part of the diet. But you can’t give hemp as feed to farm animals that produce eggs, meat and milk for sale, until tests prove it is safe and nutritious to pass along the food chain.
