Save up to 30% more calves from scours with ScourGuard® 4KC
Alfonso Martinez
Up to 30% of rotavirus scours cases are caused by Rotavirus serotype G10.1,2 and ScourGuard® 4KC is the only scours vaccine labeled to help protect against Rotavirus serotype G10. 

Scour Bos® and Guardian® labels don't compare.

ScourGuard 4KC offers the broad-spectrum protection you need against the four major scours-causing agents:

  • Rotavirus serotypes G6 and G10
  • E. coli
  • Coronavirus
  • Clostridium perfringens Type C

Works Right. Right When You Need It.
One way for calves to gain immunity to scours-causing agents is through the absorption of antibodies in the dam's colostral. Optimizing the level of colostral antibodies available to the calf is a process that begins months prior to calving, and centers on not only nutrition, but the vaccination of the heifer or cow. ScourGuard 4KC has the vaccination window that best coincides with the development of colostral antibodies.
