Risk of Exposure Questions:

Use these questions to determine your herd's risk of exposure to Trich.

1.  Do you buy/lease/borrow non-virgin bulls?

2.  Do you buy open cows?

3.  Does your herd have high risk contact with outside herds?

 

Use the chart below to determine if you have high risk contact with outside herds.

1Some grazing communities have Trich management plans in place to aid in the prevention of Trich. 

2High risk neighbors include breeding age cattle with an unknown owner, a herd with no defined calving season, an unstable herd population (i.e. trader cows), or a herd with a history of Trich infection.  All other herds would be considered low risk.
