Great Southern Agriculture Research Institute (GSARI)

Prevention of Flystrike in Non Mulesed Sheep homepage

GSARI is located east of Katanning and receives approximately 400mm of rain annually.

Currently all sheep on the property are involved in trials or supplying trials. There are 3 different times of lambing on GSARI; May, early July, early September with marking completed in mid-June, mid-July & mid-October respectively. Every sheep on GSARI is shorn in the first 2 weeks of October. A pre shearing crutch may be required and if so, is conducted in late August on a selective basis.

The main time of fly risk is confined to September as temperatures increase in October. Adults are at the greatest risk in September leading up to shearing with greatest risk to lambs being in November and December. Scouring occurs from mid July to October. Worm egg count monitoring (WEC) is conducted in April only with all weaners being drenched in Oct. Adults aren't drenched unless the WEC indicates its necessary.

There is no routine jetting and individual animals are treated for fly strike by removing soiled wool around the wound and applying Vetrazin as a hand dressing.
