First, let me preface this by saying that my goal with this feed mix is to find something that I can do myself without buying stuff from a feed store. My family is moving overseas and will not have access to all of the special ingredients that go into an optimal feed mix. I know that we can get various grains for calories, my biggest concern is making sure we provide enough good protein. So, what goes into the various protein sources in commercial feed and what is a good substitute? I won't be able to buy fish meal or animal meal, but can I make it? Is there something else, like lentils/split peas that could be used to provide protein?
