an epidemiological study of listeriosis in dairy cattle

) Use of bedding: Using straw bedding in cubicles was associated with an increased
risk of disease (OR 3.0, CL 1.12-8.76) while its use in other house types (OR 0.0 CL
0.0-0.89) was associated with a decreased risk of disease (Table 3. 15).
c) Dung disposal: Disposing of dung as slurry and not storing manure were associated
with an increased risk of reporting disease, but these relationships were not statistically
significant (Table 3. 15). Storing manure beneath the slats increased the risk of
reporting disease in winter months (OR 17.72, CL 2.26-160.7).
