Table 1

Treatment 1: 4L 1st-milking pooled colostrum, treatment 2: 2L 1st-milking pooled colostrum followed by 2L colostrum-derived replacer, and treatment 3: 2L 1st-milking pooled colostrum followed by 2L 2nd-milking pooled colostrum. †Pearson chi-square or Fischer’s exact test with 5% level of significance. SE: standard error. One-way ANOVA using the Tukey multiple comparison procedure with 5% level of significance. Means without a common superscript are significantly different. Total IgG fed for treatment 2 estimated assuming 100 g IgG in colostrum-derived replacer. |
