  milk until 21 days before calving
• Close up dry cows Within 21 days of calving
• Fresh Cows Cows that recently calved
• Lactating Cows Cows that are producing milk in
  the milking string

Calves

• Aloud to get colostrum then removed
• Bull calves fed for veal or castrated and fed for
  beef
• Heifers are grown, bred, and milked for at least
  one lactation
• Calves are put into individual pens and fed milk
  or milk replacer for 4-8 weeks
