Putting the Brakes on Bacteria Growth in Colostrum

  • In the United States we estimate that at least 45 percent of all colostrum fed to calves contains enough environmental bacteria to make calves sick.
  • About 77 percent of refrigerated colostrum has bacteria counts high enough to make calves sick (>100,000cfu/ml)
  • Warm colostrum is an ideal growth medium for bacteria.
  • Lowering colostrum temperature slows the rate of bacteria growth.
  • Adding a food-grade preservative slows the rate of bacteria growth.
These are the main points in the July issue of the monthly calf care newsletter, "Calving Ease."  This issue is available at our vet clinic web site, or just click July Newsletter.
