Cows between the ages of three and seven tend to produce higher-quality colostrum than first-lactation heifers. However, you can feed high-quality heifer colostrum at the calf’s first feeding, says Bob Holland, veterinarian at Iowa State University. Holland offers these recommendations when feeding colostrum from heifers:
1. Feed colostrum from heifers that were vaccinated appropriately.
2. Use a colostrometer to evaluate the quality of the heifer’s colostrum. Feed colostrum which falls within the “green zone” on a colostrometer.
3. If the quality of the colostrum is questionable, use it for the calf’s second feeding.
