Not all milk replacers are the same. Sure, they differ by protein source, level of protein/fat and any medications or additives included. But milk replacers also differ on how well they support gut health and protect overall calf health. While you probably have a favorite milk replacer, new research shows that adding IgY, the avian equivalent of IgG (immunoglobulin G found in colostrum), can make a good milk replacer even better.

When we look at calf health statistics for the U.S. dairy industry, it’s clear we have room for improvement. Data from the USDA’s National Animal Health Monitoring System (NAHMS) has calculated the national morbidity rate for female dairy calves at 34% and mortality at 5%, with digestive disease or scours as the leading cause of both sickness and death.
