Arguably the most important first step in the life of any calf is successful establishment of passive immunity through colostrum management. This key touchpoint ensures easy newborn calf management for weeks in the future and improved pay price for your bull calves.
Colostrum replacers occasionally need fed, for a variety of reasons. Understanding the key details of absorption, allows colostrum replacer manufacturers to optimize their product and therefore your success.
How does dilution impact the absorption of the colostrum replacer, based on the rate of abomasal emptying? Does this impact the calf’s IgG absorption and ultimately success of passive transfer? Listen in to Dr. Alberto Lopez has he describes the results of his recently released research and observations from the field.
