Ask the Vet

Dr. Ken McMillan, Contributing Columnist

READER: I read your recent article about dehorning, and while I'm not advocating the use of banding, I have had good success with the method. I did not have any anesthetics, and the cows showed some discomfort for about 24 hours. It took about 30 days for the horns to drop off, and we had no bleeding or other problems. We did it when the weather was cool, so flies were not a concern. But, your comments brought another issue to my mind, which is how do I get an anesthetic? You see, we have no large animal vets in our county, and that can leave producers like myself doing jobs we might otherwise let a vet handle.

Dr. McMillan: I am glad to hear a positive report on banding. Maybe there is a place for it, and there may just be a learning curve to get to where you are. Maybe other readers will also respond with success stories and tips on how to make it work. The old adage is that "experience is the best teacher," but I would advise anyone attempting this to work with his or her veterinarian, or someone who has experience and success with the procedure.

All pain medications, most antibiotics and many other drugs and feed additives require the producer to have a valid Veterinarian-Client-Patient Relationship (VCPR) for the veterinarian to sell the product or issue a prescription or Veterinary Feed Directive. This trend will only accelerate in the coming years.

The FDA in the Code of Federal Regulations Title 21 (CFR 21) clearly defines the elements of a VCPR as follows:

-- The veterinarian assumes responsibility for the animal's health.

-- The client (owner) agrees to comply with the veterinarian's instructions.

-- The veterinarian has sufficient knowledge of the animal(s) to make a general diagnosis.

-- The veterinarian assumes responsibility for follow-up care, including adverse reactions and/or treatment failures.

-- The veterinarian maintains patient records.

Veterinarians approach pain control very differently, but there is no question that it is the right thing to do for the welfare of the animals. The data is very clear that pain control pays for itself and also makes the producer money in increased production.

Local anesthetics like lidocaine are very effective in many otherwise painful procedures, but there is a learning curve on how to use them appropriately. Nonsteroidal anti-inflammatory drugs (NSAIDs) provide longer-term pain relief. Drugs like flunixin (Banamine) come as an injection and a topical application. Meloxicam is an economical and very effective pain reliever, but is not approved for use in cattle. It can be prescribed by your veterinarian for many conditions based on an exclusion made by the FDA. But, in every case, these drugs require a prescription, and for a veterinarian to issue a prescription, there must be a VCPR.

You also bring up an important issue for our industry as a whole. The loss of large animal veterinarians is very concerning to me, our profession and hopefully to everyone in the equine and food animal industries.

Thank you for your comments, and good luck in finding a veterinarian to work with.

VET TIPS AND TRICKS:

A quick tip on mixing vaccines: If you're not familiar with a transfer needle, this is a handy little tool to have at the ready. It's a needle with sharp tips on both ends. One end goes in the bottle containing the liquid portion of the vaccine, the other in the lyophilized (dry) bottle. The vacuum in the lyophilized bottle pulls the liquid in, mixing with the dry portion.
