Bovine respiratory disease (BRD) is a costly concern primarily during the calf phase production. This is especially relevant to veal production, when young and venerable calves are commingled from many farms. However, BVD breakouts can also occur on calf ranches raising dairy x beef calves or even individual dairy farms.
This month Dr. Stan Jourquin joins us from Ghent University in Belgium to discuss his article is titled, “Dynamics of subclinical pneumonia in male dairy calves in relation to antimicrobial therapy and production outcomes”. Listen in to learn how pneumonia might be lurking in your herd without your knowledge.
Consider ways to use ultrasound as a tool to quickly and reliability assess animals upon receipt to allow for differential management. Overall losses, from chronically ill animals, could be decreased by warding off the spread of infection and promoting early cure. Once lungs are severely consolidated, these animals are 4.2x more likely to become chronic and experience -0.25 lbs average daily gain over this phase of production.
