[Jacob-list] worming techniques

[Linda]

Cydectin is recommended in this area, but I'm reluctant to use anything that even hints of birth defects or any problems with my pregnant ewes.  I'm sure that everyone on this list know not to use Valbezen with pregnant ewes.  

A shepherd friend had the parasites in her fecals raised and then tested for resistance.  This was done at the university - doubt you could do this easily at home!  An interesting finding was that her parasites could be killed by Tramisol, which was considered totally ineffective here ten years ago.  Ivormectin works for my sheep, Safeguard doesn't.  Neither was effective on her sheep.  Conditions and situations can really vary from flock to flock even in the same area.  Mary Ellen says "If you have access to a vet, the best advice is to use them and get to know them."  IMHO, it's really important to find out what wormers are effective in YOUR area and especially your flock. 

A couple of other interesting thoughts from vets:
The more often you worm, the more chance of developing resistant strains of parasites.
Diarrhea is not always a sign of parasites.
It's not necessary to worm the whole flock, just because one sheep appears to need it.
