Alternatives to animal use for teaching

Video presentation

Details of procedure

Consider omitting the use of chemicals for demonstrations, except during the fly season when a preventative chemical should be used according to label directions. Whether chemicals are used or not, correct label directions should be followed as though the appropriate chemical were in the jetting fluid.

For demonstrations, adults with at least 3 months wool should be used. A scourable dye should be used in the jetting fluid to demonstrate the distribution in the wool and on the skin. 

Drugs, chemicals or biological agents

All chemicals must be registered, and the instructions on the label adhered to, including withholding periods and safety precautions for humans.

Impact of procedure on wellbeing of animal(s)

With careful handling, there should be no impact on the animals.

Reuse and repeated use

Animals should only be jetted once if using chemicals in a teaching situation.

Care of animal(s) during/after the procedure

Jetted sheep require shelter from wind and 1-2 hours drying time before sunset to avoid chill. Care must be exercised with yarding of heavily pregnant or lactating ewes and the resultant chill factor after jetting which can deplete the energy reserves. Lambs also need daylight for mothering up before release to the paddock.

Pain relief measures

Nil.

Qualifications, skill or training necessary to perform this procedure
