Research from the University of Minnesota shows that mixing a concentrated colostrum replacer into moderate-quality colostrum can boost antibody uptake in newborn dairy calves, matching the benefits of high-quality colostrum. This approach helps improve passive immunity and calf health on farms where colostrum quality is variable.
Use cases
- When cows produce moderate- or low-quality colostrum on the farm or ranch
- For ensuring adequate passive transfer of immunity in calves when high-quality colostrum is limited
- During times of herd health challenges or when calf scours is a concern
Why it works
- Mixing a concentrated colostrum replacer directly into moderate-quality colostrum increases antibody (IgG) levels safely and effectively
- Calves fed this mixture achieve blood protein benchmarks similar to those fed high-quality colostrum, supporting healthy immune development
- Using USDA-approved, real colostrum-based replacers ensures effective nutrient and antibody delivery, with minimal digestive upset for calves
