Colostrum Neutralizes Oral Scours Vaccine

Farmers have been using a modified-live oral calf scours vaccination program for decades. Their goal: protect calves against bovine rotavirus and coronavirus.

Has it been working? Well, we know that the incidence of scours hasn’t changed in more than 20 years.

Researchers at RTI (Research, Technology, Innovation) LLC., took a closer look. They wanted to know how colostrum can interact with these newborn scour vaccines. In their analysis, the scour vaccine was inactivated, rendering it ineffective, in the presence of colostrum.
