Part of the decision would depend on how old the cows are and what you paid for them. If they are short solid or younger and if you paid under 1,000, then I would feed them real good and sell them as pairs in March. If you paid more and have to have more, then you may need to keep them until mid summer, sell the calves, then sell the bred cows. If they are old cows, leave the calves on until late June, then pound the cows and the calves. If they are old, you probably paid around 800, so as pairs they would not bring enough in March to make much profit. The one with the big teat will get sucked down to normal pretty quick. Her teat will not get too big for a few more calves, but she may be an old cow, so you may need to feed her pretty well until spring. In years when there is pasture, I have made very good money buying old springers in December when no one wanted them, freshening them out and running them until July and pounding them out. Some years, you can buy the old pairs in March for what the springers cost in December, and those years you can make real good buying them and pounding them out in July.
