Research presented at the American Association of Bovine Practitioners annual meeting explains the need for colostrum products with 100 grams IgG or more: Within the first 24 hours of life, it’s important that a calf receives enough colostrum to achieve successful passive transfer of immunity from disease. This can come in the form of maternal colostrum, a combination of maternal colostrum along with a colostrum supplement, or with the use of a newer 100+ IgG colostrum replacement product. Research has shown that calves receiving a minimum of 100 grams IgG if nipple fed, or 150 grams IgG if tube fed, are most likely to achieve successful passive transfer of immunity. Calves that fail to achieve passive transfer are susceptible to death, disease, low weight gain and delayed calving.
Adequate colostrum within the first hours of life sets the foundation for a calf’s ability to survive and thrive. Lori H
