Selecting for fly strike resistance? Is it a selectable trait or not?

[Ysgythan]

0 Extra time checking untreated - theyre moved at intervals varying from 1 to 7 days and usually through a gate with a 10 yard race, or one set up quickly for that purpose, so I observe and pull out any I wish to look at, total time 5 to 10 mins per move without problems, + 10 mins per intervention.

Treating a Struck sheep - Generally My Approach is shear the whole thing with 12v shears any time of yaer if its struck, then treat with molecto, Remove from flock into quarantine/ death row paddock and if she has lambs, with those two.
General time, depending on where she is in relation to quarantine paddock, anything from from 5 mins to 45 mins If she needs driving their.

If I get more than 1 or 2 a month i would consider treating the whole flock.

If I have an outbreak of mucky bums (rare now since I started culling for it) I would treat the whole flock, with click, but those times appear past on the whole now thanks to culling.

I see, you don't cost your time moving the blydi things every whip stitch then? What about the electric fencing costs?

Get enough sheep, and that approach becomes impractical, as does spotting struck sheep in time.

Lots of wooly sheep - get a spray race, put them through it twice a season, and don't worry about the blydi things!

I Agree totally their - That Said Im down at 120 ewes at the moment after abig cull / needing cash quick, but was running at 230.
a) My big cull helped,
b) Running 3 mobs one of which sheds -
c) Smal fields makes spotting them easy - and useing electric alot too on anything more than 5ac.

Id imagine my system would fall apart at 400+ sheep, and yes I'd go down the route of treating, that said by the time im at 400+ id like to think my selecting and work was paying off and I was looking at flys as a negligible problem!

If I had 500 wooly sheep tomorrow, I'd probably recommission the dip!
