Winter grazing to me is one of the most glaring reasons why we should calve in th SPRING. That does not mean late February....it means after March 21st. Dry cows that are gestating take less feed than lactating cows and their calves. Another huge plus is not having to worry about freezing calves, moving cows into a barn, or muddy, scour ridden lots. Those cows can calve out on grass all by themselves. They do not need us to hold their hand. I'm not saying there won't be the ocassional wreck that could have been avoided if you were watching your cows 24 hours a day, but compared to the cost of feeding all winter, it would be a minimal setback at best. Remeber, everytime you start the tractor to cut the hay, bale the hay, move the hay off the field, haul the hay home, stack the hay, unstack the hay, feed the hay, and finally, to haul the manure out of the lots, it cuts into your bottom dollar. I don't believe that slightly, if any bigger calves in the fall are worth the extra cost. I think this would hold true for nearly every area of the country, but I do not know that for sure. Around here we graze milo stalks, corn stalks, alfalfa ground, volunteer wheat and dry grass. With a little protein or some protein tubs on the side, that will provide PLENTY of nutrition for a dry cow. God made them nearly the ultimate foraging machine!
