This is my winter "natural feeding" project. I want to figure out an optimal recipe for a rabbit feed that can be fed as a concentrate along with lots of hay and fresh greens. At the moment I am feeding a decent scratch grain with oats, barley and a bit of cracked corn, but the proportions change with the prices and I think I could do better buying whole grains and other ingredients and mixing my own. I also want to increase the protein content. At best the current mix would have about 9 - 10% protein and although some of the shortfall is made up by alfalfa and willow, I know it is likely still too low. I'd rather not use soy products, which are reputed to be hard for rabbits to digest, and am thinking that field peas may provide an alternative, along with black oil sunflower seeds and ground flax seed. I'm looking for information and opinion on the subject and hope some of you are interested enough that we can get a good discussion going.
