I have often found that if I see blood then I am usually dealing with coccidiosis and a couple of doses of corid will do the trick. Again, it goes directly to the gut tract. If it is viral, I don't know of any way to really treat it except for supportive with electrolytes and all to keep it from getting weak. I think that there has been some use of anti-biotics, but don't know if they only help to prevent a secondary bacterial infection. There is a vaccination that can be given to a cow pre-calving for the rota and corona viruses, and I believe there is something you can give to day old calves also. I usually have the coccidia and occasionally an e-coli to deal with.


We used to vaccinate the pregnant cows with Scour Bos 9 prior to calving but we now give each calf a First Defense bolus, preferably within 12 hours and rarely have scours (or at least nothing that warrants treatment).

If you already have Nuflor on hand try a normal dosage of the stuff orally. Have no idea why it works but it did for us when we had scours other than milk scours. Can;t hurt and just might help.

Nuflor is an effective antibiotic. It is not an antiviral. If the condition you describe is viral, nuflor will provide no efficacy.

The following is information from the Merck Animal Health website:

Florfenicol (nuflor, is the trade name) is a novel, broad-spectrum antibiotic discovered and developed by Merck Animal Health. It is approved for veterinary use in treating BRD and foot rot.

Florfenicol is distinctly different from other antibacterials used in animal health. It is chemically similar to chloramphenicol but has no human safety risks.


The important point: its an antibacterial, not an antiviral.


Whatever you say "BUD", how many years have you been practicing medicine?

This is the exact reason we have so many lurkers and not many new members giving advice based on their experience. There is always a know-it-all to bash their thoughts.

Since antibacterials such as oxytetracycline, draxxin, nuflor, sustain III , etc. provide no direct treatment of viruses, an alternative is to vaccinate. Many viruses can be effectively vaccinated against. In the case of calf viral diarrhea/scours, there are several vaccines. The one I use is Calf Guard by Zoetis. It has some advantages:

1. It comes as a MLV preparation. Modified Live Virus preparations provide a good immune response.
2. It comes in 3 mL individual doses.
3. It can be given to the cow/heifer 60 days before partum or it can be given orally to the calf in the first 24 hours preferably in the first 8 hours post partum.

Yes, cure and prevent. Vaccines have been effective against viruses. The example most often used is the smallpox virus.

The last known natural case was in Somalia in 1977. Since then, the only known cases were caused by a laboratory accident in 1978 in Birmingham, England, which killed one person and caused a limited outbreak. Smallpox was officially declared eradicated in 1979.

And now we can mod live a calf, sucking a cow with unknown mod live vacc history?

Or am I misremembering that that is not what is acceptable?

There is a risk of causing abortion when using a MLV for Fetal Protection. It is not a risk when using a MLV to provide immunity for Rotaviruses or Coronaviruses.

PS: the Fetal Protection includes the following diseases caused by viruses :
IBR, BVD Types I & II, PI3, and BRSV.

In fact, the vaccine (MLV) for rotavirus and coronavirus (calf guard) is administered in the last 60 days of pregnancy and at least 30 days prior to partum in order for the vaccine to elicit an immune response so she can pass it on to the calf in the colostrum.

I have never used any of it myself. My vet gave my heifers mod live vacc prior to breeding this fall. That's the only experience I have with it.

That was likely Bovi-Shield Gold FP 5. Comes in a broad range of products that cover other organisms such as Leptospira virus. It is prescribed prior to breeding. Provides fetal protection. The FP 5 means fetal protection against the 5 most common viruses that cause the diseases I referenced above. Which are: IBR, BVD Types I & II, PI3, and BRSV.
