The key to cow management in winter is to ensure that moderate body condition is achieved before the onset of cold weather. Studies have shown it is very difficult to put body condition on a thin cow during cold conditions. Cows can make substantial recovery in body condition during the post-weaning period if temperatures are moderate and forage is readily available. These conditions can be accomplished by weaning calves by early to mid-October. Weaning calves later than this may not be conducive to a "year-round" grazing program.
