Calf PreRD® is a supplement containing a source of viable microorganisms for use in calves.


Calf PreRD® establishes the microbiome to promote rumen development and gut integrity at a younger age.Packed with DFMs (direct-fed microbials), Calf PreRD uses probiotics to help maintain a more desirable digestive environment, in turn helping to stave off pathogens and aid in nutrient utilization. Calf PreRD is an effective way to help calves to ease the transition to dry feed with less digestive disruption.

When to Use: 

  • When earlier starter intake is desired
  • Following scours challenge
  • Prior to weaning
