If you don't have enough cows for loads of distillers, just get a 3-4,000 gallon tank you can lay in a grain truck or on a trailer and go to an ethanol plant and get some CCDS.  Get a 500 gallon water tank and keep it full with the CCDS.  Free choice the syrup and the garbage hay and you'll be good to go.  You'll essentially be doing the Mix 30 program without the foo-foo additives they put in the syrup to call it Mix 30 and quadruple the price.
