MODULE 11: Healthy and Contented Sheep

Background
information

Strict biosecurity measures are required to maintain freedom from economically significant diseases and parasites. Assessing the risk of disease outbreaks and adopting appropriate strategies can reduce the chances of introducing diseases that affect productivity and profit. If a disease is introduced, action must be taken to control or eradicate it.

 

 

At a Glance
Avoiding disease introduction is more cost effective than treatment

Keep footrot, lice and OJD out of your sheep flock

pt When disease is detected, take action to minimise its impact

Key decisions, critical actions and benchmarks

Assess the current disease status of your flock

Some important pests and diseases to be avoided include:

  • Footrot
  • Lice
  • Ovine Johnes Disease (OJD)
  • Drench resistance (discussed in procedure 11.2).

Be able to recognise important diseases (see tool 11.13) and avoid their introduction.

Potential sources of disease

Ask for a signed National Sheep Health Statement concerning disease history, to assess the risk of disease when introducing new sheep into a flock. Visit http://www.farmbiosecurity.com.au/toolkit/declarations-and-statements/ to download a copy of a National Sheep Health Statement template.

Sheep producers should provide a signed National Vendor Declaration (NVD) for all sheep or lambs they offer for sale or slaughter, and insist on a correctly completed copy when buying sheep or lambs. A signed NVD declares that the owner of the sheep has met the basic on-farm food safety requirements of the Livestock Production Assurance (LPA) program (see procedure 3.2 in Market Focused Lamb and Sheepmeat Production).

Complete a risk assessment of your boundary fences and policy for new stock introductions, transport and people (see tool 11.14) to identify potential disease risks for your farm.

Quarantine new sheep on arrival

Purchasing stock is a normal part of management on some farms. To minimise the risk of introducing disease, observe quarantine and induction periods during which existing sheep are not exposed to new sheep (see tool 11.15).

Control and eradicate existing diseases

Control and eradicate introduced diseases such as footrot and lice (see tool 11.16).
