Table 2: Other herd-level risks identified in some studies.

Other herd-level risk factors identified in some studies*

Contact with contiguous cattle
Indicators of badger density/activity
Sourcing cattle from herds with TB history
Providing cattle feed inside housing
Use of multiple premises
Housing type
Herd type
Farmland habitat
Fertiliser usage
Mineral deficiencies (selenium)
Use of silage clamps
Rotational grazing

*It is important to note that epidemiological studies may differ in the variables examined, the exact measures used (in relation to the association with badgers etc.), and the study size and power. Therefore, not all risk factors would be expected to be identified equally across all studies.
