Author Topic: No fly strike - why? (Read 2031 times)

Ok, so don't lynch me, but I've had four Jacobs since May, no preventative, and not a hint of fly strike all summer. Why is this? Beginners luck? Is it because they're on pasture that hasn't had sheep before?

They're shearlings, sheared in early June. My neighbour had one die of strike (allegedly, I didn't see it).

How can I replicate these conditions next year, or is it just luck!

Thanks

We live in Aberdeenshire and at the top on a wee hill and generally it's always windy and for 6 years no flystrick but this year the weather has been calmer and we had 3 cases in clean lambs at the same time so It could be lots of reasons from wind, weather, luck, amount of cover/hedging for flies to hover - from what I've learnt this year never rule it out - oh and keep checking

You may just be lucky but some sheep breeds & family lines are definitely more affected than other. Presumably just like us with midges...

I used to keep Jacob and Suffolk sheep and for 3 years on the trot I had fly strike in the Suffolks and never in the Jacobs. I put it down the the fleece, not sure if that is it but I never needed to treat them whereas the Suffolks even had click and still got struck. Could also be your location.

Don't start counting your chickens just yet. We had a case on the last day of October last year. When I went to by the Crovect the agri merchants told me they had sold 3 lots of the stuff that week.

Given the choice flies tend to choose only the very best quality wool! Even so, a couple of our Badger Face were struck in the very calm, humid weather in July this year, despite having been recently shorn. The rule with sheep is NEVER take anything for granted.
