If you just wan'ting to get them fat get some FAST FAT from Moorman's or some Sweet80 form HighPro. But if your just starting out, I would go with a good show feed, till you really learn what you can do and can't do. Feedng to much corn we BURN one up, if you burn one up you just wasted money and time. Started them out on a Grower then when it time change them to a finisher. If they ARE NOT getting finished you my add some corn. Or you could cook corn, but the probelms I find with cooking corn is that the calves LOVE it and do not wan't to eat the feed, they just wan't cooked corn. GOOD LUCK
