Colostrum management ( Table 2, Table S3 ). There was no evidence of an association between case/control status and the following variables: suckled dam within 12 hours of birth, time to first colostrum administration, number of times colostrum received in first 24 hours, artificial colostrum used. There were increased odds of exposure of cases compared with controls for total colostrum received, colostrum obtained from cow(s) different from dam, pooled colostrum, pooled colostrum includes colostrum of dam, and frozen colostrum. These variables were associated with each other so colostrum obtained from cow(s) different from dam was included first in the multivariable model from this group because it had the highest number of observations, and pooled colostrum, pooled colostrum includes colostrum of dam and frozen colostrum were nested within it.
