Comparison of paratuberculosis antibodies (IDVet, MAP, ELISA) in colostrum samples. (a). Samples from six commercial dairy goat farms (A, B, D, E Gudair® vaccinating, C non vaccinating, and F partially vaccinating. Total n = 120). (b). Samples from four Gudiar® vaccinating commercial dairy goat farms. One year, between one and two years, and more than two years post vaccination. (c). Samples from four Gudiar® vaccinating commercial dairy goat farms. Vaccinated as kids younger than six months of age, and older than six months of age. The population mean ± 1×SD is indicated per farm. The horizontal line at %SP 30 indicates positive cut-off; the horizontal line at %SP 20 indicates negative cut-off. Samples with values between %SP 20 and 30 are considered dubious. Kruskal–Wallis p < 0.0001; * Dunn’s multiple comparisons test p < 0.05.
