Ann, here's a link to the info sheet on the sheep product, which I think has also been used with alpacas down under.

http://tiny.cc/ic9li

I believe Chuck Rademacher is familiar with it. Personally, I don't know why any fecal occult blood test wouldn't work - vets test for that all the time with cats and dogs. I'll have to ask my vet about it - the cynical side of me says that having a special new dipstick is really a special new way of making money. I know that this is "calibrated" to show levels of infestation, but honestly, it seems like all you would need to know is if there's blood in the feces or not...

Hi,

I guess the question would be if there was some low level would you not treat? In sheep with famacha you don't treat when they are little pale. That means they have some parasites really it means they have some level of barber pole but you don't treat. In the interest of not developing resistance you would not want to over worm. So if they had a little blood would you not treat if they were otherwise healthy?? Is a little blood okay? Sounds scary but that is the Famacha principle in sheep basically you are not treating animals that have low levels. Sheep can tolerate to a certain extent and fight off low levels but I'm not sure alpaca can.

Hi,

The info I kind find on the haemonchus dipstick test developed in Australia seems to indicate its a pooled test of 10-20 animals? I just have no idea what use a pooled test is at all.

Since it was developed for sheep, I think they're just interested in how groups of animals in particular pastures are doing.

In alpacas, I would think that if you suspect Haemonchus in an individual animal, any blood in the feces would be cause to treat - so any fecal occult blood test should work unless it's species-specific (there are some proprietary to horses that I know of).

OSU will do fecal occult blood testing:

And I would really think that your local vet should be able to do it, too, given how common a diagnostic tool it is in companion animals...

Hi,

I wonder if it would be possible to do the test yourself, how hard could that be? I've found human test kits online but they are pricey.

I'll keep investigating.

Thanks for the info

Hi,

I asked my vet about the fecal accult blood test and she said she had heard at a conference from Chris Cebra that fecal accult blood testing was not reliable in alpacas. Rats! I'm hoping she is going to the Oregon conference and can find out some more details.

I bought one of those faecal occult blood kits. Have used them in the past when I suspect gut bleeding either from ulcer or worms. Have only had one positive with an animal that had Black Scour Worm.

Going to do some more of my own research. Sometimes I get high test results when people send me samples. Will see if these show positive. Trouble is I don't get the opportunity to test many. Had my sheep show positive at 250 epg but their faecal occult blood was negative. Its a shame someone like the Government testing labs arent doing some sort of comparison.
