Calves from vaccinated dams did better in the feedlot

Canadian study looked at protection from respiratory and viral diseases

A uniquely Canadian study provides the first comprehensive look at feedlot health outcomes for calves from dams vaccinated before conception with Express FP. Dr. Tye Perrett, a managing partner with Feedlot Health Management Services, Okotoks, Alta., oversaw the project that reviewed Canadian feedlot records on 1.4 million calves born between 2007 and 2014 to compare […] Read more

Antibiotic alternatives for livestock producers

Antibiotic alternatives for livestock producers

Research on the Record with Reynold Bergen

Antibiotics are a tremendously valuable tool in livestock production. For example, at this time of year, groups of lightweight, freshly weaned, shrunk-out calves with an unknown vaccination or nutritional history arriving at a feedlot after being transported long distances from pre-sort sales in cool, wet, fall weather are likely candidates for bovine respiratory disease (BRD). […] Read more

Atypical interstitial pneumonia in cattle

Vet Advice with Dr. Ron Clarke

Atypical Interstitial Pneumonia (AIP) continues to plague the beef industry in unpredictable ways. Also known as acute bovine pulmonary emphysema and edema, AIP is a common cause of sudden respiratory distress in cattle, particularly adult beef cattle grazing lush pastures through late summer and fall and in feedlot cattle through the finishing period. Sudden onset […] Read more

Immunostimulant Zelnate cleared for Canada

Immunostimulant Zelnate cleared for Canada

Animal Health: News Roundup from the September 2016 issue of Canadian Cattlemen

Bayer HealthCare Animal Health’s Zelnate DNA Immunostimulant introduced in the U.S. last fall is now approved and available in Canada. It is the first of its kind among a new generation of products for cattle that kick-start the innate immune system when given at the time, or within 24 hours, of a disease challenge. According […] Read more

Pneumonia: the disease that won’t go away

The three categories of pneumonia and how to tell them apart

Environment, germs and immunity are top of mind when thinking of all the risk factors that could set the stage for pneumonia in cattle. The forgotten factor is one beyond producers’ control and the reason why pneumonia will always be a problem — anatomy. Bovine lungs are very small relative to the animal’s oxygen requirements, […] Read more

Deadly cattle condition called fog fever returns to the Prairies

Deadly cattle condition called fog fever returns to the Prairies

Cases of fog fever, a type of pneumonia that causes severe cattle mortality, 
have been recently diagnosed in Alberta

Fog fever — a condition that causes cattle to suddenly drop dead — has returned to Alberta and Saskatchewan. “Fog fever isn’t extremely common” said Nathan Erickson, a veterinarian and assistant professor at the University of Saskatchewan. “Some of these old diseases, we start forgetting about them because we’ve managed our way out of them. […] Read more

Intranasal vaccination could protect young calves from BRD

News Roundup from the May 2016 issue of Canadian Cattlemen

Bovine respiratory disease (BRD) is a major animal health problem in feedlot cattle. Presently, BRD makes up about 65 to 80 per cent of feedlot diseases and 45 to 75 per cent of deaths in many lots. The financial toll of BRD on North America’s cattle industry is more than $1 billion per year. Previously, […] Read more

The AMR Dilemma: Part 2 – The impact

The AMR Dilemma: Part 2 – The impact

Finding the missing pieces to the puzzle of antimicrobial resistance

Although accurate statistics are difficult to tabulate, over two million people in North America become infected with bacteria resistant to antibiotics annually. At least 23,000 people die as a direct result of these infections. Virtually, all significant bacterial infections in the world are becoming resistant to the antibiotic treatment of choice. Health authorities in North […] Read more


preparing a livestock vaccine

Understanding the value of vaccines

Although vaccines have been used commercially for more than 70 years, the bulk of vaccines available on the market has not changed significantly. They are still mostly the products of either live or killed whole virus or bacterial culture. Research has yielded improvements to adjuvants (components that stimulate immunity), introduction of genetically engineered subunit and […] Read more

Conjugation, and what it means for antimicrobial resistance in livestock

Conjugation, and what it means for antimicrobial resistance in livestock

The federal government’s CIPARS program studies E. coli in healthy cattle entering packing plants and in retail ground beef. Its surveillance shows that resistance to antimicrobials of the highest importance in human health continues to be very rare in these samples, and multi-drug-resistant bacteria are even less common. The risk of consumers being exposed to […] Read more
