OSU team addresses economic impact of BRD  
A multi-disciplinary team of Oklahoma State University scientists and practitioners is riding herd on one of the most challenging concerns of Oklahoma's $4.6 billion cattle industry: Bovine Respiratory Disease.

Animal health companies continue to invest in R&D 
Despite economic conditions, Animal Health Institute member companies spent $671 million in 2008 to research and develop potential new products and to maintain the longevity of existing products.

2009 symposium first in 25 years to focus on this costly disease.

The cost of BRD 
Research from Iowa State University, recently reported in the Journal of Animal Science, shows the economic impact of bovine respiratory disease on performance and carcass value in feedlot cattle.

Nothing to hide 
Long before anti-agriculture animal-rights groups began distributing clandestine videos of abusive behavior, the beef industry has actively engaged in initiatives to help assure humane care throughout the beef-production chain.

Ranch vs. auction-market calves
All calves are not created equal. And when calves come into the feedlot setting, an eye needs to be kept on meeting each group’s individual needs, whether they are ranch-direct or a group of put-together sale-barn calves.

35 Years of Feedlot Medicine 1972–2007
A lot has changed in the feedlot industry in the last several decades. Feedlot veterinarians were asked to recall the disease challenges, issues, tools and events that happened in the last 35 years that have impacted feedlot medicine and the management of feedlot cattle.

Feedlot antibiotics and their impact
Antibiotics have been used in food animals for decades. The much-amended, but still in effect, Federal Food Drug and Cosmetic Act was passed in 1938, providing for the safety of drugs in the target species.

The impact of feedlot BVDV
Bovine viral diarrhea virus (BVDV) was first recognized in the 1940s. One of the first meetings of the Academy of Veterinary Consultants in 1972 discussed the impact BVDV had on feedlot respiratory disease. Today the discussion continues, but now is laced with terminology including immunohistochemistry, cytopathic/non-cytopathic and persistent infection.

Economic and Quality Impact of Disease
Respiratory and other diseases of feedlot cattle not only rob the animal of economic value in terms of weight gain and treatment costs, but they also have an impact on carcass quality. The information that follows demonstrates this loss.

BVDV in the feedlot
Being transported and then arriving at a feedlot is a stressful time in a calf or stocker animal’s life.
