KDSC, as you can tell just by the few responses that you have gotten on this question here that there are sooo many different ideas about what to feed your cattle and what works best, but I will add my 2 cents worth. First of all, to answer your question about frame. Frame score will be decided IMO by genetics primarily, so forget about balancing your ration for anything to do with frame. Different sizes and ages require different protein levels. Rule of thumb, the younger & smaller the calf, the higher the protein level. Generalization 18% starter rations down to 12% for finisher rations. The bigger the calf, the more that they can eat which causes lower percentages of protein eaten per lb, but more total lbs eaten per day. Follow?
Another reason that you don't get a lot of responses to this question is that no one knows where you live and what kind of economical feasible feedstuffs that you have to work with in your area. That makes it almost impossible to help you, until you give us the products to work with, thus this is why most people go to town and buy what they have or tell you to buy. If you want to get good @ making your own rations, you need to buy a book which includes most of the feed stuffs and their digestable nutrients for beef listed. Now if you stop a second to think about that it can be a bit mind boggling. I am from Iowa State area, and am old, so the book I recommend is Feeds & Feeding by Dr. Jurgens. I don't know what the latest edition will be, but you will be amazed at what you can feed cattle. So, for us to help you, you will first need to decide what products that you have in your area to use and what % protein that you want the ration to end up @. I will need to go start trying to find my old feeds & feeding book so that I may be able to solve for X. The formula that we used to use was called the Pearson square, and was really simple to use assuming that you aced algebra in high school. Just kidding about acing the class, but see you can use it in the real world. Hey, if one of you younger pups out in the syber world wants to jump in about now, feel free then I won't bother to go try to find my old book. It's been between 2 & 3 decades buried somewhere. I will go look KDSC, if no one else can help us here. I honestly think that the simpler that you keep the ration the better off you'll be. There are some great rations out there, and some people have very strong ideas about what you should feed, but really there are no big secrets. Feed your calf cattle feedstuffs. You can deffinantly fine tune feeds as you go, but don't make it anymore complicated than it has to be. I'm sure that Dan's ration works very well and if the ingredients to make his ration are available to you, that may be the best place to start. Here in Iowa right now for our calf projects all weighing in the 600s, we are feeding a mix of cracked corn, dry gluten,( most we have ever fed b/c of corn prices),soybean hulls, cottonseed hulls, and shredded dried beet pulp, no hay to speak of. We have 10 head in the pen and they are eating approx. 16lb/hd/day. We will slowly increase this or keep it to what they will clean up in about 20 minutes twice/day. Again, IF YOU WANT TO GET GOOD AT BALANCING RATIONS, YOU'LL NEED TO GO BUY A BOOK TO READ, or you'll keep getting vague answers and more frustration b/c there are so many different answers. The ball is in your court. I will go try to find my old book if you want me to, but I will wait for your reply, or hope that one of our smarter members chirps up. I hope this hasn't confused you and maybe you have some more insight as to why members haven't jumped right in, but hope that we can have an ongoing project for everyone here.LOL.
