1
J, Jersey; H, Holstein.
2
Result for each calf at first positive or last negative E, ELISA OD405 nm (≤1.4 considered negative), A, AGID (positive/negative); F, Fecal culture (cfu/2 g).
3
Age at which calf first tested positive for either E, A, F or if E, A, F were negative, age at final test.
4
nd, not tested.
5
Clinical Stage (Whitlock and Buergelt, 1996).
6
One male was tested at five months of age (no evidence at the time for clinical Johne's disease) because of a non-paratuberculosis, presumed eminent, lethal condition.
