There is a major hay shortage in my area this summer. I managed to get 60 bales at a decent price, but I calculated that I would need more like 90-100. Can I feed beet pulp or hay cubes to supplement the rest of his forage needs? Or would I be better off coughing up the extra dough and buying the expensive hay. Also I might be getting some bales from a cattle farmer next to my property, but I am not sure the quality of the hay he has, so I don't want to count on it as a primary food source.
