Running a profitable stocker operation can be a real balancing act. Not all pastures on any one operation will be of the same quality. And not all calves on that operation will be all of the same class either. You must match the best combination of available grass to the cattle you have.

For example, 600-pound calves have a lower protein requirement in relationship to intake than 400-pound calves. Meanwhile, the young, growing forage in properly burned range will be higher in quality than unburned pasture.

Consider putting the 6-weight cattle on lesser pastures and put the lighter cattle on better quality pastures. Because heavier calves have more capacity for intake and can eat more, they can still get the nutritional requirement they need. The lower quality forage will not impede performance to the extent that it would on lighter weight calves.
