“Must-do” management recommendations…

  • Good air quality and ventilation are critical.
  • Maintain plentiful, clean, dry bedding at all times.
  • Excellent dry-cow care and vaccination; calving environment; and colostrum delivery are all necessary to get autofed calves off to a good start.
  • Locate feeding stalls within three feet of the machine to keep milk transfer lines cleaner.
  • Follow manufacturer’s recommendations for automatic cleaning and sanitizing.
  • Perform manual cleaning according to manufacturer’s recommendations.
  • Clean and/or replace nipples at least daily.
  • If calibration is not automatic, re-calibrate machines at least once a week.
  • Be sure to account for water volume when calculating solids content of reconstituted milk replacer. (Example: 150 grams added to a liter of water = <13% solids)
  • Do not use soft water to mix milk replacer, as sodium toxicity can result.
  • Feed starter grain with a protein content commensurate to the milk-based diet. Provide free-choice and keep supply fresh and clean.
  • Provide plenty of fresh, clean, free-choice water. Clean waterers daily and separate from starter grain to prevent cross contamination.
  • Don’t dehorn, vaccinate or move calves at the same time they are being weaned.
  • Empty feeding pens and sanitize between groups of calves.
