"Slaframine poisoning (Slobbers) (Figure 1) should be considered, especially in a cooler and wetter spring or fall. Spring and fall provide ideal environmental conditions for the proliferation of clovers in pastures. The cooler wet conditions are also ideal for the growth of the fungus Rhizoctonia leguminicola, commonly known as black patch. The fungus infects red clover (Trifolium pratense), white clover (Trifolium repens), alsike clover (Trifolium hybridum) and alfalfa. The name ‘black patch' is derived from the bronze to black spots or rings observed on the leaves and stems (2). Rhizoctonia leguminicola produces the mycotoxin slaframine or slobber factor. It can be present on both pasture and in stored dry hay. The fungus persists on infected fields from year to year. Slaframine can be active in stored hay for 10 months or more; however, its biological activity does decrease. Fresh hay can contain the equivalent of 50-100 ppm slaframine, which can decrease after 10 months by 10-fold to 7 ppm. Concentrations above 10 ppm may be associated with clinical signs (3). The analysis for slaframine (1-acetoxy-6-amino- octahydroindolizine) is not readily available.
The most common clinical signs observed in horses include: excess salivation, lacrimation, colic and diarrhea. One case reports abortion in a mare (4). Clinical signs often develop 1-3 hours after consumption of the contaminated forage and subside 48-72 hours after withdrawal from the offending forage. Atropine may provide symptomatic relief of salivation and diarrhea (3).

Slaframine poisoning is non life threatening.
No treatment is necessary, except changing the feed.
Clovers can be an excellent source of nutrients but are occasionally associated with excessive salivation, oral ulcers, laminitis, colic, photosensitization and liver failure."

OMG! Praying that they have a speedy recovery.
Keep us posted!
Thinking about ya girl!
Thanks, KDW, the drool has stopped and I gave Kola some more pro-bio and a dose of banamine before I leave for work and she's prancing around now asking Steve to feed some more! They are doing well.
Sounds like you caught them in time, thank goodness!
I'd never heard of slobbers before so thank you for including the info so I didn't have to ask lol
Glad to her they're doing better! I know that clover could cause slobbers, but I didn't realize the other side effects, I just thought it was unsightly! I'm glad you didn't have to deal with colic or worse...and that you caught it early on!
Hope they are feeling better soon, that's awful.
CDNCowgirl, I actually found the info through a Canadian Vet site.
JJ, Funny, though, what I have is white clover rather than red. I had always thought that white clover was not the issue that red is.
Thanks, Arlene......Will be busy next week clearing the pasture entirely and they'll be pissed at me...LOL
Wow, lots I didn't know about slobbers! Glad they'll be ok.
As for the coyotes, we've got the same problem. Bold lil devils, sit right outside my fence howling in their unGodly manner. I shoot at them too if they won't leave when I yell at them.
They make me nervous, not to mention they try to eat my dogs.
mikey, They're aweful creatures! Here you can shoot to kill them year around with no limit as they are such a nuisance.
Thanks for the info, I had never heard of slobbers. Glad they didn't get laminitis out of it!!!! I'm still dealing with that after a year and a half. As far as the pets question of your last post, our horses and ponies are definitly pets. Now our town zoning disagrees and calls them livestock so we had to get a special permit to have them here as we are on the fringe of a housing development even though we have 400 acres.
I'm lucky here as we have only 2 acres but in the middle of farm and zoned Ag.
Goodness Callie, I am glad they are okay! This was educational for me though, thanks for sharing the information. We have some clover around here, I will have to look at it and make sure it doesn't have those spots.
Hope you get a handle on the coyotes....I'm sure your girls will feel safer.
I'm glad to know that Kola goes well now. I did not know this desease. It's true that here, the weather is very dry.
Glad your girls are going to be allright.I didn't know about slobbers, so thanks for posting that information. I try to avoid having clover in the pasture as I had a horse founder on all 4 feet from it; we ended up putting him down. Around here we have a lot of clover and it's really hard to buy hay that doesn't have any in it. I find that it tends to get mouldy because it cures slower than the rest of the hay crop.
Thanks gals, I'm glad I was able to put the info out there, unfortunately at the expense of my girls, but it's a lesson learned and a completely mowed and weed killed pasture!
