Livestock electrocution can be natural or man-made

Animal Health: Make sure tools and electrical services are properly installed and maintained

By
We’ve all seen pictures and heard of the cattle deaths following severe lightning storms. Cattle are susceptible because they are so well-grounded. They often gather along fence lines or under tall trees, seeking shelter when lightning strikes. There really is no prevention for this other than to make sure all fences, especially electric fences, are […] Read more

Be alert to bovines consuming ‘software’

Animal Health with Roy Lewis: Twine, plastic, rope — there is a good chance it could end up in an animal’s gut

By
I just completed an autopsy on an older well-doing calf that got suddenly sick dehydrated and toxic-looking. My daughter, also a veterinarian, did an autopsy on a mature cow that was losing weight and going downhill, becoming emaciated and weak. Even though both these clinical signs seem different, as well as the age difference between […] Read more

Taking a look at a new antimicrobial product

It's important to look at the pros and cons, if any, and ask questions

By
These days all antimicrobials, NSAIDs and a few other products are prescription products with most coming under the VCPR (veterinary client-patient relationship) requirement. NSAIDs stands for nonsteroidal anti-inflammatory drugs. It is best that producers educate themselves on new, emerging products that may benefit their operation or management style. Everyone needs to realize that any new […] Read more

Due diligence with Johne’s disease

Have animals tested and cull infected cattle early

By
Johne’s disease (pronounced yo-knees) as we all know, is the paratuberculosis organism that in livestock can cause diarrhea, weight loss and eventually death from starvation or condemnation at slaughter due to emaciation. Animals that test positive, provided they are still in good body condition, can be slaughtered for human consumption, as the disease does not […] Read more

Leptospirosis in cattle is difficult to study

Animal Health: Often affects beef reproduction and can reduce milk production

By
We struggle in veterinary practice in Western Canada to make sense of the leptospirosis disease complex, as it can be hard to substantially diagnose. Leptospirosis is caused by spirochete bacteria that infect lots of different animal species but only certain serovars (variations within bacteria) are really pathogenic to cattle. Pomona and Hardjo are two variations […] Read more

Bison and sheep need to keep their distance

Animal Health: Malignant catarrhal fever can quickly kill mature bison

By
One of the serious diseases we see in bison but much less frequently in cattle is MCF or Malignant catarrhal fever, usually resulting from some interaction between bison and sheep. The MCF family of diseases is seen in 33 species. Clinical signs are a high fever, lethargy and weakness, with ocular and nasal discharge leading […] Read more

Survey reveals improvement needed in parasite management

Animal Health with Roy Lewis: Internal and external pests need different treatments

By
Over the last few years there has been a lot written about internal worm control, timing of chemical treatment and parasite resistance. A group of researchers from the Western College of Veterinary Medicine in Saskatoon asked producers in 2015 about how they were using internal parasite treatments. The researchers drew some good conclusions from this […] Read more

Adapting management practices to changing times

More online services keep the beef industry operating

By
While COVID-19 has changed our daily routines, the internet has been able to keep us going. The agricultural community has tapped into it and fortunately, the supply chain for veterinary pharmaceuticals, feed and other services has been maintained pretty well. Internet sales for the purebred bulls and commercial cattle have pretty much saved the spring […] Read more

Dealing with diphtheria in calves

Several treatment options to get animals breathing again

By
Upper respiratory problems in cattle include diphtheria — the common name for infection/inflammation of the vocal folds of the larynx (voice box) at the back of the throat. Infection in this area is called necrotic laryngitis. Swelling from the inflammation can restrict the airway and make breathing difficult. In acute cases, the calf may die […] Read more
