Transmission pathways were dependent upon seasonal temperature and Rest/Graze behavior.

Proportion of total average counts of incident cases accounted for by each pathway for each factorial combination of Rest/Graze and Drinking condition. Cool condition = cattle always rest in the field and spend more time grazing; Warm condition = cattle always rest under trees as a group and spend less time grazing; Dep condition = cattle rest/graze depending on temperature. Drink condition = Dep if drinking condition was dependent on temperature; Drink condition = Indep if drinking rate was assumed static (at 20°C rate).
