AVOCADOS ARE POISONOUS TO HORSES! So is the tree, the bark, the leaves… every part!






I had no idea that avocados were poisonous to horses.

Just this weekend, a horse nearby passed after ingesting avocado leaves.

Very sad.

Avocados – all parts… leaves, bark, branches, roots, shoots, pits and fruit are poisonous to most livestock and dogs.

I live in California, so this is good to know…

But, even if you don’t live in an avocado area, most of us (sometimes) feed our horses what we might be eating that they are sniffing.

I mean, c’mon… some of us (me) have been known to give-in to those huge, pleading eyes by breaking off a bit of whatever yummy thing we were eating … happily allowing our horses to snorffel  up whatever we give them.

Well, I could just see myself eating chips and guac and not thinking a thing about handing over a loaded chip to my horse.  It never would have occurred to me not to – except for the fact that I wouldn’t give my horses chips.

Avocados are good for humans… but NOT for animals.

So, just remember, avocados are NOT OK.  Not anything about avocados are good for most any livestock.

Don’t pasture your horses where they have access to avocado trees, either.  The bark, branches, leaves, buds and fruit are all very bad.

Yummy avocados are POISON to livestock.

Every part of the plant is bad - leaves, bark, branches, roots, fruit and seeds.

Whorled Milkweed. (Asclepias verticillata): VERY TOXIC – this is what killed the 19 mustangs!






Take a really good look…

Whorled Milkweed.  Look familiar?

Whorled Milkweed. Look familiar?

I’m not sure if any of you read about he 19 mustangs in the BLM Prison facility in Canon City, Colorado who fell ill and died…

Well, it turns out that their round bales included Whorled Milkweed (Asclepias verticillata).  This weed is what killed them.

So sad and so fast!

These horses were down almost immediately.

Take another look – and then tell me that you recognize it.

I do.

If you see it in your hay, DO NOT FEED IT.

I don't know why the horses ate it... maybe it masks its poison to smell and taste.  dunno

milkweed

VERY COMMON

This weed pops up on the edges of fields and along roads.  It is very hearty and thrives…

Asclepias verticillata L.

Whorled milkweed, Eastern whorled milkweed

Asclepiadaceae (Milkweed Family)

USDA Symbol: ASVE

USDA Native Status: Native to U.S.

Whorled milkweed is a single-stemmed, unbranched perennial, 1-3 ft. tall. The narrow, linear leaves are whorled along the stem. Small, greenish-white flowers occur in flat-topped clusters on the upper part of the stem.

Because of its toxicity to livestock, this plant is considered a weed in range areas.

I’m sure this kind of thing is why hay farmers spray…  Clearly, whomever was buying the hay for these BLM horses wasn’t using a reputable hay distributor.

So sad.

I guess for the locals, this was bittersweet news.  Their water wasn’t contaminated, but their wild horses died.

Another angle...

NEWS ARTICLE

I found this article…

CANON CITY — Authorities have determined a noxious weed likely caused 19 wild horses to become ill and die at the East Canon Prison Complex where they are cared for by inmates until they find new homes.
According to BLM spokeswoman Lauren Gapinski, the ingestion of whorled milkweed, a highly-toxic plant, is suspected to have caused the deaths based on preliminary lab results issued from the Veterinary Diagnostic Lab at Colorado State University. The weed was in the hay fed to the horses.

The BLM has been working to probe the cause of the illness that killed 11 horses Dec. 3 and another 8 on Dec. 4. Some of the horses died on their own while others had to be euthanized due to their conditions.
This week, nine of the horses also in the same pen that exhibited similar symptoms have recovered or are recovering quickly.

ANOTHER VIEW

FROM A VET WHO IS A READER

I must admit that when I first saw this report, I had to look up whorled milkweed (Asclepias verticillata) in my copy of A Field Guide to Common Animal Poisons. Milkweed contains cardiac glycosides, the natural substances from which heart medications like digoxin are derived. When ingested in toxic doses, the cardiac glycosides in milkweed stop the heart from beating normally. Very often, poisoned animals are simply found dead, but symptoms like diarrhea, loss of appetite, depression, weakness, unsteadiness when walking, collapse, and seizures may be noted in more mildly affected horses (or other species, for that matter).

MONARCH BUTTERFLY CATERPILLAR eats this weed to protect itself from being eaten.  Smart.  Ol' Mother Nature at work.

THIS JUST IN FROM A READER WHO IS A BIOLOGIST!

As a biologist, I am actively involved in protecting species at risk. Here in Arizona, we have recently become aware that the Monarch Butterfly uses our rivers and streams as over-wintering and way-station habitat. Many are trying to help them survive and thrive, and the use of various milkweed species in landscaping and revegetation settings is encouraged. Obviously, it should be eradicated near forage crops, however! Readers of Horse and Man should be encouraged to appreciate milkweed in appropriate settings because of its benefit to Monarchs (as well as several other butterfly and moth species that are at risk), but as noted in the article, be diligent in keeping it out of forage crops and the hay we feed our horses and livestock.

All the best,
