We wean our fall calves born in Sept/Oct the middle to the end of February, we just weaned a week ago. We have creep feed out for the calves from November on. After weaning, the requirements for the cows goes way down, that is why we wean early, put the feed resources into the calves instead of feeding the cows enough to provide enough milk for the calves. The cows can go back out and graze old grass instead of being fed hay every day. We use the same amount of hay now as we did when we calved in Feb/March. Our calves then go out on grass until late August, early September when they go into a feedlot. They then come out of the feedlot towards the end of February when there is a shortage of ready cattle so they usually bring a premium there. The advantages of fall calves are mostly options, if it does not rain I can sell them in April/May on the highest market of the year, or if it rains I keep them and grass them. We do not vaccinate for scours and we have not had a sick calf since we went to fall calving. Our weaning percentage is usually over 100% with twins. We run just as many cows as we did when we spring calved, and we do it with no hired help, just us so we are growing more pounds of beef with way less inputs and way less stress on us, we do not check even heifers at night or work even half as hard as we used to.
