Siberian elm could potentially be used for tree
hay, but there's not a lot of specific info out there about it. Since you’re already making tree hay from willows, you’d probably follow a similar process. The leaves are eaten by goats, so they might be okay for your cows and
chickens too. Just make sure you dry and store the elm properly to keep it from going bad.It might be a good idea to test it out with a small batch first and see how your animals like it. Keep an eye on them for any issues. If you’re unsure, it could be helpful to chat with a
local expert or nutritionist to get some advice. If possible, consult with a local agricultural extension office or a livestock nutritionist to get more tailored advice and ensure that the feed meets the dietary needs of your animals.
