Durvet DuraFense Paste is a colostrum supplement with functional proteins and live direct-fed microorganisms, designed to support newborn beef and dairy calves. It provides host-specific DFMs to help establish normal gut microflora and includes high-quality bovine colostrum for optimal immunity. The egg-based functional proteins aid in digestive balance, supporting calves when E. coli, Salmonella, Rotavirus, Coronavirus, or Clostridia are present. Ideal for use whenever colostrum deficiency is suspected, it promotes healthy growth and overall calf health.
