The thing that bugs me about Kit, is he is always shooting down the other seedstock breeders in the country. He always says that everyone is overfeeding their bulls and everyone has to big of cattle. That is a huge generalization. Some are fed to hard and some are to big. If you need to shoot down other people tomake yourself look better or to become successful, then something is wrong.
I think that a 2 to 4 frame cow is to small. Those cattle will finish out with to small of a carcass, an most cattle at that size will give you alot of yield grade 4's because they will beome little butterballs. Now not all, but most of them.
Now saying that, Kit does have some good ideas. We winter graze all winter long, it is alot cheaper than putting it in a bale, hauling that bale home, then hauling it out to feed. Iron and fuel are too expensive for this ranch. But it may not work for everyone. We calve in May and June and have more live calves, no frozen ears, and they don't need good feed, because they calve out on green grass.
I think that a 1300 to 1400 lbs cow is ideal. You will get heavy weaning weights, they will kill at the right weight, and yet they won't eat you out of house and home. This is what works in our enviroment. Ya, some of the cows get bigger than that, but some are also smaller.
As far as feeding corn to cows. I have no problem with that, if corn is cheaper than other feed. I do have a problem with it if you are feeding corn to them to get them into or keep them in condition. Then you probably need to change genetics some.
