I've seen more cattle die from heavy worm burdens (6 within the last two years, no, they weren't mine) than from worming (zero to date). Under normal circumstances, I disagree with your hypothesis that the cure is worse than the disease.

Never lost any calves or cows to de-worming and I always de-wormed my herd every spring before I turn them out in their summer pasture. How often you de-worming your own herd?

I am in total disagreement. Not on the problem you stated with the vet and University, but on the convention of using a parasiticide. I know something or two about parasites. They can be some of the most disgusting creatures nature has invented. I have seen cattle in poor condition treated with a parasiticide turn into beautiful well conditioned animals that live a much more content and healthy life. I would not want to be in this business if I had animals suffering from parasites and could not do anything about it. Thanks to drug companies, I can fullfill my responsibilities to the animals in my care. If you don't have any parasites be thankful, but they are here, all manner of round worms, flatworms, ticks, flukes, mites, lice, etc. Many have life cycles that devastate the animals lungs, livers, digestive system and other organs. They may have a place in nature but I hate them in my animals including my blue healer which I also use ivermectin on.

I have given ivomec to calves year round. Bought alot of rough cattle that had never even seen a human until they got to the sale barn and never lost a calf to the wormer. I'm guessing the vet gave the wormer to your cattle because it is a good management practice and he may have felt sorry for the cattle. Nothing more pitiful to me than a calf with a full worm load.

I decided to inform anyone who has not noticed that the package insert for Ivomec now has a black box warning about heel fly infestation and that it can cause death if administered at the wrong time. I believe that this post had a major impact in Merial labs disclosure of a major adverse effect.

Anytime you have an extremely heavy infestation and kill a parasite off, the dead parasites can out out certain chemicals, cause swelling, or leave holes where they were attached causing a chain reaction that could lead to death.

I understand the OPs anger. But as many have already stated, if you are worming them on a routine schedule the parasite load should never get to a level to harm the animal during "die off." Your cattle were most likely over loaded with larvae.........Did any show up post mortem?
(The migrating warbles are also not common here, according to my vet.)

There were 9 calves posted , 6 by the vet and 3 by the MU pathology dept but they did not look for parasites in those areas according to their reports even though I told them Ivomec was probable cause. An oversight???

I thought most everyone was aware of heel flys(warbles) and grubicides.

Why were you having the involvement of a vet in the first place? and a government vet?
You can treat the cattle easily and cheaply yourself rather than pay a vet a lot of money to do it for you.

I was unable to find help to work the cattle at the time. I had the cattle up so I called the vet school and had the vet and 4 students to work them for me. I reluctanly went with the vets recommendations. All I wanted was the cows and calves sorted and the calves vaccinated with 7-way vaccine. It was one the costliest mistakes for me.

The parasites should have been pretty obvious, I would think. :roll: That sounds a bit odd that they neglected to check for them.
However, I do believe that if the cause of death was a huge parasite die off, you are more to blame than the manufacture. The Ivomectin did what it was designed to do.

The cows and calves were all healthy and they all looked good. Parasites have been around for millions of years and ivomec only temporarily reduces their number. It totally imazes me that people think that it is better to kill an animal with Ivomec than to not give it. Must be alot of industry brainwashed people out there.
