Bovine Colostrum Increased Performance & Recovery Times with a Reduction of URTIs

Aim: To assess oral supplementation of bovine colostrum to evaluate earnings, performance recovery and incidence of URTI in racing horses

Protocol: The study design was a randomized cross-over racing performance study. 21 horses in race training were randomly assigned to train and compete with (100g/d) or without BC supplementation. After each horse competed in three races, it was crossed over to the other group, allowed a three week washout period, and then competed in three additional races.


  • Horses on BC supplementation earned $ 2,088 more purse money per race, than when unsupplemented (P=0.016), and ran an average of 5 BRIS speed points higher (P=0.03).
  • Horses returned to racing on average 7.5 days faster (16.9 days vs 24.4 days, P=0.048).
  • There were no URTI among the horses on BC supplementation and two infections while not on BC supplementation (z-test, P=0.11).
  • Statistical analysis showed that horses recovered more quickly, earned three times more money and raced better as judged by BRIS scores while competing with BC supplementation.
  • BC supplemented horses also experienced fewer URTI, although positive trending, the effect did not reach significance.
