Veterinarians Updated on Pain Control & Anesthetic Use in Food Animals

 

Providing pain control prior to and following surgical procedures is becoming more commonly accepted - and requested - by producers for their food animals. That was one of the messages brought to veterinarians by Dr. Bob Streeter, a veterinary clinician from Oklahoma State University, during the 2018 James Bailey Herd Health Conference, held February 10, 2018 on the campus of South Dakota State University.

 

Common procedures such as castration and dehorning have long been considered potentially painful for animals, but only relatively recently have products and techniques come to light for veterinarians to use to reduce pain associated with these surgeries.

 

Streeter explained that there are some benefits to the presence of pain: it's the physiologic response that makes the animal protect an injured part of the body, for example. When pain becomes chronic, however, many adverse effects on the animal have been documented, including impaired immune, cardiovascular, digestive, and neurologic functions.

 

Furthermore, for some animals, the physical and psychological stimulation present during some painful conditions can wind itself up to the point where severe stress sets in.

 

Veterinarians commonly use medications to preempt pain in surgical situations. One of the most common examples is the use of local anesthetics to block nerves when preparing for surgery such as a C-section or displaced abomasum correction. However, these medicines are also increasingly being used by veterinarians prior to more minor surgeries such as dehorning and castration.

 

In a similar manner, providing medications that will inhibit pain for hours or days following the procedure is also becoming more accepted. Just as a person might take a pain reliever after a minor surgical procedure, veterinarians can give similar medicines to animals.

  

 

Even though the benefits of pain relief for food animals have been increasingly well-documented, barriers to their use still exist.

 

These include drug residues, cost, worker efficiency, routes of administration and availability of the medications.

 

Since these treatments are applied to food animals, the risk of drug residues is a serious consideration.

 

Veterinarians are usually able to use these medications under extra-label drug use provisions, but it is then up to them to determine an appropriate slaughter (or even milk) withdrawal to implement.

 

A major stumbling block for many producers and veterinarians is that the fact that giving a local nerve block or administering pain medication represents extra work steps and slows down the processing of large numbers of animals.

Video: Ask A Farmer: How are broiler chickens raised in Canada?

As more and more Canadians become removed from farms and ranches, many people have questions about how animals are being raised on Canadian farms. Tiffany Martinka is active on social media and has made a point of sharing how their family farm takes care of their chickens. In this podcast, Tiffany explains the audited programs that all Canadian farmers must follow and describes how this system of raising chickens is unique in a global setting.

The main points of this podcast include:

What it is like on a broiler chicken farm and the process that chicken farmers go through.

The different programs that farmers must follow, and be audited on, to be licensed to sell broiler chicken in Canada.

The full circle of practices on Tiffany’s family farm, including growing their own feed for chickens, then recycling the manure back onto the fields to grow future crops.
