Facts about antimicrobial resistance

While the industry is already doing a good job, there is ongoing room for improvement

There have been volumes written on antimicrobial resistance (AMR) in the last several years. And it is important to remember just how good the Canadian cattle industry is doing in managing AMR and look to future changes veterinarians may make in their recommendations. For those of you craving more detailed information, there have been several […] Read more


Preventing parasite resistance to worms and flies

Developing and using good protocols will keep these valuable treatments working for you and your herd

We heard years ago about resistance with fly tags. I believe the first one was called Bovaid and with no other tags on the market, researchers noticed resistance developing after a few years. Soon other companies were making tags with a different family of chemicals in them, so producers could rotate them and not allow […] Read more

Taking aim at dart gun pros and cons

Effective yes, but they need to be used with the proper diagnosis and product

Remote drug delivery (RDD) devices are becoming more common in some modern cow-calf operations. The older-style capture guns used in the past were generally used by veterinarians to tranquilize and “capture” cattle needing further treatment. Tranquilized animals could then be loaded and transported if that was necessary or put in a smaller compound if further […] Read more


Meconium staining of newborn calves is a red flag

This spring think of meconium as an early warning sign of many things

As a veterinarian over the past 35 years I’ve been called many times to assist with difficult calvings or malpresentations that resulted in meconium (first manure) stained calves. The jury is still out on what causes this and what we should do about it. Veterinarians have many opinions on this topic, as it is a […] Read more



Improper cervical dilation at calving

Recognizing when it's happening is your first step

One of the hardest calving dilemmas you or your veterinarian face, is improper cervical dilation. Before expulsion of the fetus the cervix normally relaxes, softens and opens up essentially as wide as the vagina to allow the fetus to enter the vaginal vault. When this does not happen normally, or is delayed, the health of […] Read more


Extra equipment for your calving kit

Calving/Equipment with Roy Lewis, DVM

Just as a good mechanic has specific tools for specific jobs you too need specialized equipment during calving season. Each piece should be clean, disinfected and accessible when calving, and a little practice with this equipment beforehand is always beneficial. You may not need these particular tools often, but when you do they can save […] Read more



Practical ways to reduce our use of antibiotics

The livestock industry has made great strides in addressing the topic of antimicrobial usage and indirectly lessening the opportunity for the formation of antibiotic-resistant bacteria. From veterinarians setting treatment protocols to cow-calf and feedlot producers implementing effective coping strategies, progress is being made in minimizing the incidence of disease and thus reducing the need for […] Read more


Steer clear of fatigued cattle syndrome

Animal Health with Roy Lewis, Dvm

A few years ago cattle from an Amer­ican feedlot went down during transport to a packing plant and others developed severe lameness. This condition was eventually labelled fatigued cattle syndrome and became a huge animal welfare issue due to the appearance of severely lame, non-ambulatory cattle. Initially beta-agonists were incriminated but numerous studies have essentially […] Read more



The benefits of palpating heifers

There are both economic and health benefits for your cattle operation

Many commercial or purebred producers and auction markets are realizing the benefits of palpating heifers pre-breeding. This can also be done at pregnancy checking and involve a more thorough exam than simply a determination of whether they are pregnant or not. I will try and high­light some of these and explain how this may economically […] Read more

Criteria for selecting the right antibiotic

There are a lot of factors at play and all of them need to be 
considered in every case where antibiotics are an option

Although a few very effective antibiotics have been removed from the marketplace over the years, the choice has never been greater. The challenge is there are so many factors hinging on the outcome, so deciding which antibiotic to use — or if one is necessary at all — can be a very difficult decision. Also […] Read more
