Bottle Jaw/Sericea lespedeza?

I have four Barb/Kat lambs that are 3 mo. old. A few days ago I noticed they had the throat-latch swelling that is possibly bottle jaw/Barber pole worms. They hadn't been wormed yet, so I drenched them with Ivomec. I have two year old wethers that had the swelling about 6 weeks ago, and it went away after worming. It has always seemed to effect spring lambs in the past, and before I knew what it was, the sheep seemed to deal with it without treatment. I guess that's the Barb/Kat natural resistance at work? I've never had losses to this.

I read that it can take up to 72 hours for the worms to be expelled. Question: for those of you who have had this parasite in their sheep, did you see adult worms in the poop after worming? Was it easy to see them?

In my research I came across articles about the invasive plant Sericea lespedeza, a legume, being useful for decreasing parasite loads when used as feed for sheep and goats. It seems it is produced primarily in the south. I'm in California, never heard of it or seen anything like it in feed stores, baled or bagged. I'm wondering if any of you have used it, have access to it, etc. Apparently it is most effective in pelleted form.

You won't see the worms
They are too small.

Sericea lespedeza is high in tannins, which helps control worms, but can also be harmful to your animals if they eat too much

Keep an eye on them- do you know how to check their lower eyelids for color? If it IS Haemonchus (barber pole) then their eyelids may be light pink or white. And if you are in an area where Haemonchus is resistant to avermectins, you may need to use Safeguard (fenbendazole).

Good luck!

Ivomec doesn't work on barber pole - well, at least here it doesn't and I learned that the bad way. Wish I saw this http://attra.ncat.org/downloads/goat_barber_pole.pdf sooner.

Ours are Katahdins too. In my experience, by the time when you actually see the bottle jaw you only have a few hours or not even that and I've never seen one recovering on their own from that stage.

My young lambs tend to get those too. It is a fat deposit from drinking lots of rich milk!

Google "milk goiter".

wIt must be the milk thing, though I've seen it go away fairly quickly (as far as fat goes at least), AND the yearlings who had it weren't nursing :-) I've never lost a sheep that has had this, though, so Barber pole doesn't seem likely if it is that acute when the bottle jaw shows up. These lambs are white and their skin around their eyes seems very pink, didn't get a good hard look at the inner eye lids, but not white when I did try to check. They hadn't had a first worming yet so it wasn't a bad thing they got wormed.

I did my own fecal check of fresh clumps taken from inside the shed these babies and their moms are in at night; don't know whose clumps they were, but there were very few parasite eggs of any type. I've got access to a microscope at work, and I made my own saturated salt flotation solution. I had been giving DE for about a week prior to this, and this was before the "bottle jaw" showed up. Could be a ewe's clump (poops are clumpy right now), could be they were worm free before the DE and it just isn't parasites.

I'll google milk goiter :-)

Good to hear! If it IS haemonchus, the lower eyelids are very pale or white-almost grayish. You "know" when they have it- and in lambs it can be fatal by the time you see it. If it's "just" milk goiter, that eventually goes away.

If you are in an area where Haemonchus is resistant to Ivermectin, check with your extension agents to see if they've heard about treatments that do/don't work.
