Damage From BRD Estimated at $1 Billion Annually and Dr. Jim Sears Says Stress on Young Cattle is The Main Factor
Fri, 30 Oct 2020 08:18:25 CDT
Bovine respiratory disease (BRD) has been a reoccurring and expensive challenge for cattle producers and Dr. Jim Sears, veterinarian and senior technical advisor with Elanco Animal Health said stress is the main reason.
Ron Hays Beef Buzzes With Dr. Jim Sears
It's a very complex disease and it's frustrating, Sears said.
We have made a lot of progress in many ways over the years, Sears said, but there is no common cure and it triggers off stress.
Stress is a frequent visitor to many herds this time of year when calves are being weaned and shipped, diets and feeding schedules are changed so there is just a lot of stress for that animal, Sears said.
Economically, this is one of the bigger challenges for cattle producers. The estimate is around $1 billion annual damage to the industry, Sears said.
Most producers know BRD as basically pneumonia or an infection of the respiratory system, Sears said.
The overall model is stresses and if they accumulate and compromise the immune system, pathogens can get a foothold, he said. Exposure to a virus can cause further damage and bacteria can take over, Sears said.
We're usually treating bacteria as that is what causes the most damage to the lungs, Sears said.
