*Only risk factors which had significant positive influence on infection of cattle are displayed. Intercepts represents female for sex, large for herd size,

adult for age and treated for treatment. Binomial was the family used with maximum likelihood. Where Odd Ratio (OR) < 1 indicate negative direction while OR > 1 indicate positive effect.
