Great video. Great to see Targeted Selective Treatment, FAMACHA, and Bioworma being promoted.

Thank you very much. Do the lambs contaminate or get parasites from their mums by milking?

[@susanschoenian4021]

No worms are passed in placenta or milk. Dewormer is, though (some, e.g. moxidectin).

[@MokanAkbas]

I appreciate. I learn many things from your videos.

If Zero grazing is used How long does the doe and kids need to stay off pasture?

[@susanschoenian4021]

It depends on what your goal is. Eventually all of the worms will die off and egg counts will be reduced to zero. But it takes several months for this to happen. Sheep/goats raised in confinement don't usually have worm problems.

@@susanschoenian4021 I meant immediately after kidding we Jug them for about 3 to 7 days before putting out during the day with the herd. Is that long enough?

@@dori1oakes Sorry for not answering in a timely fashion. The PPER peaks anywhere from 2 weeks before to 8 weeks after lambing/kidding. 30 day son average. So really, you'd need them in the whole periparturient period to get the full benefit. On the other hand, any days spent off pasture are days that aren't being contaminated with worm eggs. BioWorma is a good alternative to keeping animals off pasture.
