Johne'S Beef Assurance Score

Johne’s Beef Assurance Score

The Johne’s Beef Assurance Score (J-BAS) is a risk-profiling tool developed for use in the new

approach to Johne’s disease (JD) in beef cattle. It is to be used as a guide and, when introducing

cattle, producers should ask further questions about JD in the herd and other species on the

property from which the cattle are sourced, rather than rely on the score alone.

Johne’s Beef Assurance Score (J-BAS) [numbers equate to Dairy Score]

Two successive negative Sample tests 2 years apart,

and ongoing triennial Check Test

High assurance

One negative Sample test a minimum of 5 years

after the last confirmed clinical case (or if no history

Assurance

of disease) and ongoing triennial Check Test

No history of JD on property or minimum 5 years since last

Managed disease

clinical case confirmed on property

risk

If previously infected, minimum of 2 years of biosecurity plan

implemented and since last clinical case of JD confirmed on property,

plus all high-risk animals identified and removed

Progressing

If no previous infection, biosecurity plan in place for 2 years

Biosecurity plan in place

Clinical case(s) removed

First steps

Suspect, infected and unknown

Unmanaged risk

*All plans must be documented. The National Farm Biosecurity Reference Manual - Grazing Livestock

Production provides a guide to use for the property biosecurity plan. All plans should include the JD

in Cattle Biosecurity Checklist.

Having other JD-susceptible species (sheep, goats, alpacas) on the property does not affect the score

for the cattle herd, but cases of JD in these species must be considered when deciding the score for

the cattle herd.

A clinical case is an infected animal with weight loss +/- chronic diarrhoea, that does not respond to

treatment.
