How did you expect to get real help with such a lack of information? If you told a vet only what you wrote here, I can't imagine what they may have figured out.

This was your first post and no one knows you - we can be very helpful if we have the information. Unfortuately too many people join just to make up things and have fantasies about horse ownership. How did you expect people who don't know you try to figure out if you are for real or another person in make believe with nothing more then your first post? This is just some advice for anyone new to a forum, give as much information as possible.

Sorry to hear that you lost two horses.

Your last post is not visible, so I am guessing it was deleted. But really there isn't much that people can do to help if you don't have access to a vet. It sounds like you lost your second horse even with a vet there, so there was nothing a bunch of people on the internet could have done to help you.

Sorry for the loss of your horses. Thank you for coming back to post what happened & warn others of a lesson learned the hard way.

I'm so sorry that you lost your horses. It's hard enough to lose them but to lose them in such a tragic way. I definitely second the previous posts that say you should contact the manufacturer. They should be held liable for having directions to feed a toxic ingredient to horses. It's horrible!

I'm also sorry it is so difficult to get a vet. I had emergency a couple weeks ago and was frustrated by the 45 minute wait (and the $110 fee). I will appreciate my proximity to help more in the future.

I hope you give us another chance on the forum. Some people can be quick to judge and even quicker to offer snarky "advice"

Any feed mill is liable for any feed that contains a medication or chemical that is not clearly labeled. They carry product liability insurance for that purpose. The Purina Mill in Kansas City had a mixing error put Rumensin in horse feed about 25 years ago. That was the first time I heard of it. It killed some $100,000.00 + horses and they paid for them and the Vet bills.

If you still have a sample of the feed and can have it confirmed what happened, you can file a claim with the feed retailer and the manufacturer and they will stand behind it.

It is against all rules and regulations to have mis-labeled feed and to have feed that contains any ionofores (what Rumensin and Bovatec are), non-protein Nitrogen (urea) and any other chemical or medication that is added to the natural feed ingredients in any feed.

OP I am so sorry about your losses :(

I too would be contacting a lawyer regarding the feed and taking it to court. there is no excuse why the company/Mill should advise that it be fed to horses.

I would also be contacting the feed store to tell them what happened so they don't recommend it to anybody else for their horses ! (if not already done)

Are there other horses in your area that have been affected? I'd think that the feed store sells to more than just you.
