Final model estimates for preweaning morbidity and mortality events in a randomized trial of the effect of feeding a lacteal-derived colostrum replacer (CR) compared to pooled maternal colostrum (MC) in calves
Outcome Type of colostrum Number of calves β coefficient (SE) P value OR* (95% CI)
At risk Events
Diarrhea Lacteal-derived CR 295 47 -0.540 (0.212) 0.011 0.58 (0.38 to 0.88)

Respiratory disease Lacteal-derived CR 295 63 0.007 (0.205) 0.974 1.01 (0.67 to 1.51)

* OR is the ratio of the odds of outcome in calves fed lacteal-derived CR to the odds of outcome in calves fed pooled maternal colostrum.

** Calves raised from birth to weaning without morbidity or treatment with antibiotics.
