I have a chance to buy some small holstein heifers. I know that good milking holsteins are bringing pretty good money at the sales.I now know why most dairymen keep all there heifers. Anything in particular that I should look for? Any suggestions on raising these to breeding age? I seen in a local market report that some were listed as supreme and approved. What does this mean? I don't know much about holsteins. Any suggestions would be appreciated. I'm always wanting to try something new. Thanks!!!!
