overcrowding heifers in a pen can cause some of them to become overweight, while
others become too thin. These variations in bodyweight can cost you money. “It’s hard to see these dollars, but it is an extra cost,” says Jud Heinrichs, dairy science professor at Penn State University. Chart your heifers’ weight and height regularly. Among those heifers in the same pen, try to keep bodyweight and height within a tight range.
