I know someone using the mineral with Garlic in it and says it really helps with the ticks.

Using mineral with very high levels of Chlortetracycline is more of a prophylaxis than a treatment.

I use vitaferm heat in the summer. It includes garlic which some say chases away ticks, mosquitoes, flies, etc.

I'm much much further north than you and had a horse get anaplasmosis like 3 years back, most likely from a tick.

So apparently winter doesn't hamper it at all.

Imazol might be an easier drug to use at the rate of 2.5ml/100kg SC. That is if it is available there.

Lucky_P posted this on the thread "Anaplasmosis".

The level of CTC allowed in mineral will only protect up to a 750 lb animal - and then, only if they're eating their theoretical 4oz of mineral every day. There's (That's) not enough, and consumption is so variable, that I would never trust CTC-medicated mineral to provide 'protection' for mature cows/bulls. It might help, but the likelihood of 'breakthrough' cases is pretty high.
For effective 'control' of clinical disease, cattle need to consume 0.5mg CTC/lb body weight DAILY throughout the vector season(Apr-Nov here). Note that those animals consuming that level of CTC can/will still become infected... they just will be far less likely to develop clinical illness and die.

I use vitaferm heat minerial with igr and had a walk through sprayer and still got it, couldn't seem the keep the dang flies off them. he told me to feed this top dressing stuff that has that Chlor what ever it is in it. He cut one of the dead cows down the side to look at the membrane and it was all yellow looking, tod me that was a sure sign.

Rollinhills,

What is the commercial name of the feed dressing? Is it something you top dress feed with after you put feed in a bunk? I assume it is a concentrated Chlortetracycline.

I have another suggestion. If the cows were on very green grass, and all of a sudden just dropped dead have they looked at " ACUTE BOVINE PULMONARY EDEMA AND EMPHYSEMA" ? It is from a change to lush pasture and causes changes in the l-tryptopan in their system and then causes other changes in the gut which allows this to get into their blood stream and causes a type of pnuemonia. It is complicated but let me tell you, it can cause death in 1-3 days with little or no warning. It is more common in fast growing lush pastures in the spring or fall.
We lost 12 cows to it in 2 days and barely saved 4 cows and the bull. It does not affect calves. We moved the cows on Sunday, checked them on Tuesday and closed the gate, the owner called on Thursday afternoon, and said there was a dead cow or something he could smell. We got over there, found several dead cows, called the vet, did an autopsy on one at 9 p.m. that night. Got the others loaded the next morning after opening the gate and moving them back into the previous pasture. Then treated them at the vets office. There is plenty of papers on it but the answer is to use monensin in the mineral which inhibits the growth of the l-tryptophan in the gut and stops the problem. Our calves were in the 300 lb range, but we had just rotated the cows to a new pasture and in 4 days, had this happen. We did soil tests, water tests, autopsies, and finally a vet in the practice did some research and came up with that. In the meantime, spent alot of money treating and subsequently saving the 4 cows and the bull.

Please give it some consideration. With all the rain most places have had, and the grass having these growth spurts, it is a possibility.

Here's what a typical anaplasmosis cow looks like at necropsy; all fat and connective tissues will be yellow, due to hemolysis causing hemoglobin breakdown products to accumulate faster than the liver can process them.

Spleen will be enlarged and 'pulpy'.

That’s what it is, vet wrote me a VFD and I went to Burkmanns and picked it up, and yes I put it on the feed, I feed 30 head 5# 2 times a day for 5 days.

And another. This one includes a Drovers link about a ranch manager I know personally that lost a lot of cows to anaplasmosis.

No cardiac lesions to speak of.
Cows don't have 'heart attacks' like humans...virtually none of our domestic animals do.
Acute death occurs due to lack of sufficient RBCs to carry oxygen to brain and other organs
