Biosecurity research reports

Bovine Johne’s disease (BJD) is an infectious disease of cattle caused by Mycobacterium avium subsp. paratuberculosis (Mptb) that can also affect other ruminants such as goats, alpaca, sheep and deer. It causes chronic wasting and incurable diarrhoea leading to deaths in mature cattle. Subclinically affected animals may have reduced growth and milk production levels.

The WA cattle industry needs to determine what level of protection from BJD incursion and spread is required for WA, including at the border, and how this is best achieved. The primary decision to be made is whether BJD is best managed on a statewide basis …

Infection with Mycobacterium avium subspecies paratuberculosis (MAP) has been associated with reductions in milk production in dairy cows and sub optimal fertility. The aim of this study was to highlight the production losses associated with testing MAP ELISA positive in Irish dairy cows. Secondary objectives included investigation of risk factors associated with testing MAP ELISA positive. A survey of management practices on study farms was also conducted, with examination of associations between management practices and herd MAP status.

Blood samples were collected from 4188 breeding animals on 22 farms. Samples were ELISA tested using the ID Screen Paratuberculosis Indirect Screening …
