What I said was "Maybe she got through the winter OK because she went into winter fat because she did not raise a good calf." That is pretty much saying what you are saying.
If there was a point I was trying to make it was that some thought should be given to wintering cows in two groups, when a cow begins to loose condition move it to the herd that is getting better feed. It will save a lot of feed overall. You can cull based on that or not as you see fit.
A cow that goes into the fall at 1250 and looses 30% of her body weight over winter will weigh 875 come spring. That is not much cow left. Hopefully she is not going to calve for another two months or she is in trouble. A 1800 pound cow that looses 30% will weigh 1260. That is going to be pretty hard on that cow. My opinion but I think a cow that goes into winter in real good shape might stand to loose about 10% but I personally would be uncomfortable with any more than that. A cow that goes into winter in only fair shape will have to pick up weight.
