With the recent warm spell it’s time to think about preventing blowfly strike.
Female fly are becoming active and laying eggs. Strike can develop very quickly, with the first maggots appearing within 12 hours of eggs being laid!! Strike leads to reduced growth rates, skim/carcass damage and can even cause death.
Carcasses, dirty backends, foot rot lesions and open wounds are all attractive egg laying sites.
Prevention involves:
* Shearing or dagging to reduce faecal contamination of the fleece
* Thorough worm control to reduce scour in lambs…discuss worming plans with us
* Prompt treatment of lameness including footrot and wounds
* Prompt removal of fallen stock
* Avoid grazing sheltered or shaded pasture where possible as these areas are likely to harbour more flies than exposed pasture
* Use of fly traps to reduce the overall fly population on farm
Correct application of a suitable product is essential to ensure maximum protection for the flock. Check the datasheet or ask us for advice before treatment. Not all fly products are preventative - some offer only treatment so it’s essential to make sure you are using the right product for the job!
