Important to follow proper implanting technique for calves

Growth implants can generate at least a 15:1 return on investment

By
After all these years, implanting is still one of the most underutilized management tools in beef production. The feedlot sector has pretty much adopted implanting routinely, but the cow-calf sector lags far behind. It is one thing if “natural, hormone-free, or organic” beef is being raised and implants must be avoided as part of these […] Read more
Cattle oilers are effective for controlling parasites, but only use insecticide for a limited time during the season — long enough to control the pest, but short enough to reduce risk of insecticide resistance.

Timing is key for effective use of cattle oilers

Animal Health with Roy Lewis: There is a recommended window for when control products should be used

By
In light of the ever-increasing issues with lice and flies affecting production in our beef herds on summer pasture, it’s a good time to review cattle oiler pros and cons and suggest a bit on maintenance and a few tips for better utilization of oilers in the battle against these two underestimated parasites. Cattle oilers […] 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

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

Keeping animal diseases away from humans

Animal Health: Veterinarians are part of the team of essential workers during COVID-19

By
Every year the Canadian Veterinary Medical Association (CVMA) has a theme for Animal Health Week in October. This year’s theme was “Understanding Zoonosis” — diseases that humans can get from animals. Not one animal-borne disease in recent memory has affected our lives more than COVID-19. There are lots of other diseases ranging from more minor […] Read more
Proper testing can serve as a surveillance program to better understand what diseases kill livestock.

BSE testing and the positives to your cattle herd

Animal Health with Roy Lewis: Testing is still needed to demonstrate producers' due diligence

By
In Canada, we have to keep up our BSE testing numbers to maintain and improve our status as a “controlled (low-risk) BSE risk country.” Along with testing to determine if a suspicious or downer animal has BSE, as a side benefit the veterinarian conducting the autopsy and sample collection can also determine the cause of […] Read more

Great information on improved cattle handling

Animal Health with Roy Lewis: Plenty of resources to help reduce stress on people and livestock

By
We’ve all come a long way in our cattle-handling ability with improved skills, improved methods, and equipment and facilities that have become more refined. Lots of resources have been put into better understanding of proper handling practices. One I suggest checking out is Merck’s Creating Connections website. It can help producers raise healthier cattle and […] 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
