New nasal spray may provide relief from BRD

By focusing on the microbiome in the respiratory system, a new startup hopes to control shipping fever without antibiotics

By
Research into a promising alternative to antibiotics that prevents and treats bovine respiratory disease (BRD) has investors and the beef industry buzzing. “My interest is to understand how the microbiome influences the animal’s overall health and response to disease,” says Dr. Christopher Belnap, co-founder and CEO of Resilient Biotics, based in North Carolina. The Microbiology […] Read more

Linking probiotics and respiratory health

Studies on the bovine microbiota show the possibility of using probiotics to help prevent bovine respiratory disease

By
Ongoing studies are leading scientists closer to the development of an alternative to help prevent and treat the beef industry’s costliest disease. Researchers at the Agriculture and Agri-Food Canada (AAFC) research centre in Lethbridge, Alta., are developing a probiotic to help reduce the incidence of bovine respiratory disease (BRD). Though several studies are still needed […] Read more

Feedlot health starts with the cow

While the industry has gotten better at managing disease, cow-calf producers can reduce even more health issues in feedlot cattle

By
Some of the biggest health challenges in finishing cattle can be minimized or even prevented long before the animals arrive at the feedlot. In fact, calves can be set on a path to better health before birth, according to veterinarian Dr. Greg Dimmers of Metzger Veterinary Services in Linwood, Ont., to help address what he […] Read more

Vaccinating for bovine respiratory disease

Research: News Roundup from the November 2019 issue of Canadian Cattlemen

By
While bovine respiratory disease is often thought of as a feedlot problem, it’s also the most common cause of death for nursing calves older than three weeks, notes the Beef Cattle Research Council’s blog. Several studies have shown bovine respiratory disease (BRD) peaks seasonally. For example, a Nebraska study that looked at several years of […] Read more
BRD or shipping fever is associated with recently weaned calves or calves that have recently arrived in the feedlot. Keep an eye out for chronic respiratory infections as well as acute cases.

Biofilm infections hamper detection and treatment of shipping fever

Research is underway on ways to dissolve the biofilm that protects bacteria in many cases of bovine respiratory disease

By
Keep a closer eye on the chronic, less obvious cases of bovine respiratory disease, says one researcher. These infections often involve a biofilm in the respiratory tract, protecting the bacteria and making it more resistant to antibiotics. Dr. Thomas Inzana, associate dean for research at Long Island University’s College of Veterinary Medicine, has been studying […] Read more

Immune test in the works to fight bovine respiratory disease

Research: News Roundup from the April 2019 issue of Canadian Cattlemen

By
Several cattle industry organizations are collaborating on a project that could help fight bovine respiratory disease, Farmtario reports. The high-immune test for Angus cattle will identify genetics that are better able to fight the disease. Semex, Angus Genetics Inc., the Canadian Angus Association and the University of Guelph are working together on the project. Genome […] Read more

Chute-side diagnostics for bovine respiratory disease remain elusive

Vet Advice with Dr. Ron Clarke

By
Speakers at the 2019 Western Canadian Association of Bovine Practitioners addressed bovine respiratory disease (BRD) from several perspectives, including emergence of changing patterns of respiratory disease, economics of BRD, prudent use of antimicrobials in prevention and treatment of BRD, and diagnostics. BRD accounts for approximately 75 per cent of feedlot morbidity and 50 to 70 […] Read more

High-risk calves a welfare concern

Vet Advice with Dr. Ron Clarke

By
Bovine respiratory disease (BRD) accounts for 65 to 80 per cent of the morbidity (sickness) and 45 to 75 per cent of the mortality (deaths) in feedlots. Dr. Dan Thompson of Kansas State College of Veterinary Medicine, speaking at the University of Calgary Veterinary Medicine 2018 Beef Cattle Conference on managing high-risk calves, highlighted the […] Read more

Bovine respiratory disease from the farm to the feedlot

Research on the Record with Reynold Bergen

By
Weed seeds and invasive species may be present even in well-managed pastures and rangelands, but it is hard for them to germinate, establish and spread in healthy, competitive forage stands. Stresses like severe drought, overgrazing, heavy traffic or excavation can weaken forage stands and create opportunities for unwanted plants to take root. Researchers are now […] Read more
