Chute-side diagnostics for bovine respiratory disease remain elusive

Vet Advice with Dr. Ron Clarke

By Dr. Ron Clarke April 3, 2019

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

Bovine respiratory disease from the farm to the feedlot

Research on the Record with Reynold Bergen

By Reynold Bergen September 29, 2017

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

Calves from vaccinated dams did better in the feedlot

Canadian study looked at protection from respiratory and viral diseases

By Debbie Furber May 31, 2017

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

Research on the Record with Reynold Bergen

By Reynold Bergen November 23, 2016

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

Research has yielded improvements to adjuvants (components that stimulate immunity), introduction of genetically engineered subunit and […] Read more
