Lucky_P what do you do on your own herd?

If we experienced it... we'd be vaccinating.
In the face of an outbreak, we'd treat affected animals with Long-acting oxytetracycline injection and, I guess, start feeding.. somehow... CTC.

As I've related in the past, whole-herd treatment with LA-OTC may prolong the outbreak - if you treat animals in the early, incubation stage of the infection, as soon as the drug wears off, the pathogen picks right back up where it left off, and you may have new clinical cases 3-6 weeks later, when you're thinking you're 'home free'.
I'll dig around my files and see if I can find an overview I wrote a while back.

Is there a vaccine that you could reference? I could find only one vaccine and it is described as experimental.

Currently, there is only one vaccine available for the disease, manufactured by University Products LLC, Louisiana State University (LSU), Baton Rouge, La.

That's it.
'Experimental' is govt. regulatory speak.
It's a formerly fully licensed product that's been around for 30+ years... but was dropped by the big vet biologics manufacturers and released back to the folks who initially developed it.

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 think he miss interpreted what he heard/read. There are two label claims, one for cattle UP TO 700 lbs. And then one for cattle over 700 lbs. The dose is bw dependent, legal dose range is .5 to 2.0 mg/lb body weight/day to treat an "active case". If it's at 2.0mg/lb of bw for your size of cows and you typically get consistent mineral intake I think you would get somewhat reliable control, but certainly not perfect.

We have a trivalent vaccine to cover 2 Babesia sp as well as Anaplasma marginale. It is a live vaccine and basically consists of diluted blood containing attenuated organisms. You order it as needed and is made up and dispatched immediately and has to be used within 72hrs. One dose is all that is needed. I routinely do all my bull calves just after weaning as at that age you don't get the occaisional reaction. I live west of the ranges and ticks are not an issue however once you go east of me down to the coast ticks are endemic along with Tick Fever. Vaccinating allows my bulls to be sold to the coast with minimal risk.

Kenny, I don't know if they've actually named it and at least initially it wasn't available in all states. I do know that one of the breeders where we buy bulls uses it and most likely gets it through their vet but the 2nd link below provides contact info for University Products, LLC (manufacturer).

Why I Am Not Going to Vaccinate. Yet!

1. It has not occurred in my herd but it has occurred in this region.

2. It is not transmitted from cow to cow. The cow has to get it primarily from a TICK. Flies are not thought to be a vector of importance.

3. I change needles between each cow.

4. I see my cows everyday and I keep them treated for ectoparasites.

There is a study being conducted in Kansas that is focused on determining what percentage of the tick population actually has Anaplasma ssp. in their system. The researcher is doing the work as part of the requirements for a PhD at Kansas State. He has collected thousands of ticks and is in the process of determining what percentage of them are harboring the Anaplasma ssp.

Tick poisoning can be manifested as tick paralysis and hyperhidrosis, which can lead to respiratory failure and even death in cattle. Babesiosis exists where ticks are present. Tick-borne fever is a benign Rickettsia disease caused by Ehrlichia phagocytosis parasitic on white blood cells. Ixodes ricini and Falciparum falciparum are carriers of tick-borne fever. Anaplasma is caused by tick-borne Ehrlichia parasite, which can cause rupture of host red blood cells.

Treatment: 0.2% fenitrothion or 0.25% fenthion, 1% malathion, 0.2% pest enemies and 0.2% phoxim emulsion were sprayed on livestock at 200 ml/time in sheep and 500 ml/time in cattle, once every three weeks. Fluorophenyl ether pyrethrin can also be used, dosage of 2 mg per kg body weight, a back pouring, 2 weeks later, repeat 1 time. Oxytetracycline injection can avoid bacterial infection and has anti-inflammatory effect, and the price of Oxytetracycline injection on the market is not very high.

Seeing most vaccine guns etc use same needle, will spraying with alcohol or rubbing alcohol between shots do the trick.

How do you do multiple injections on hundreds or many animals, maybe thousands, if your changing needles each time.

Worked ours yesterday. I prefill disposable syringes/needles but there's 2 people giving shots, one on each side. When I do use repeater syringes, it takes less time to switch out a needle than getting 'em in the chute.

I wouldn't trust just spraying with alcohol as blood can get inside the needle.

Small herd here, only 80 cows max. Every one gets their own needle for each set of injections, and have for the past 12 years - I may use the same needle to give that cow, say, a dose of Spirovac(lepto bacterin) and a dose of Clostridial bacterin - each drawn up in separate syringes - but no animal gets stuck with a needle that's been in another animal... except steers... and the occasional heifer that we KNOW is not going to be staying here. And we do not go in-and-out of bottles of vaccine or medication with needles that have been in an animal.
It's a minor pain, but there is no way in h-e-11 that I'd use a 'repeater syringe' in my herd, without changing needles between animals. We're an anaplaz-clean herd, so far, but at one point in time, I had close to a 90% seropositive rate for BLV... and I'm certain that *I* was responsible for that. As a veterinarian, I KNEW better... but as a cheap, lazy human, I'd reuse needles 'til they got so dull you couldn't push them through the skin anymore. I've not had the nerve to re-test the entire herd to see if I've made any headway in decreasing my BLV seropositive rate, but I've not lost a cow to lymphosarcoma in quite a few years.
Disposable needles are cheap, cheap, cheap. Spreading a blood-borne disease like anaplasmosis or BLV isn't.

That, or destroying the effectiveness of some vaccines ..are id atleast think it would...
