Bovine Respiratory Disease
Activity monitors, new sensor applications and artificial intelligence could help veterinarians identify respiratory disease earlier and make better use of herd data. Dr. Curt Vlietstra sees opportunities ahead, while emphasizing that technology must work in the realities of the farm.
Researchers developed an endpoint multiplex PCR assay to detect major viral agents associated with bovine respiratory disease, potentially offering a more accessible option for veterinary diagnostic laboratories.
Five years of diagnostic surveillance reveal age-related and seasonal patterns in bovine coronavirus detection, alongside continued genetic variation.
Feeding equipment, aspiration and ear, nose and throat problems can contribute to respiratory disease. Learn what to look for when investigating recurring pneumonia in calves.
A 60- to 90-second chute-side scan can add information about pulmonary disease severity, pneumonia type and treatment prognosis.
New resistance-to-diarrhea and resistance-to-respiratory-disease PTAs give producers another tool for long-term calf health selection.
Dr. Paige Schmidt-Rios explains why bovine respiratory disease remains one of cattle medicine’s most complex challenges — and why better information, not necessarily more treatments, may be the future.
Researchers at Penn State are developing the CalfHealth System, an AI-powered platform that combines behavior monitoring, precision livestock technologies and veterinary diagnostics to identify calves at risk for bovine respiratory disease before obvious clinical signs appear.
Many calves develop pneumonia days before showing symptoms. Lung ultrasounds are helping veterinarians detect the hidden disease earlier.
Subclinical pneumonia is quietly driving treatment costs and long-term performance losses, but thoracic ultrasound is giving veterinarians a way to finally see it.
New research suggests bovine coronavirus is not just spreading nose-to-nose but through the air calves share, adding urgency to ventilation and housing design decisions.
Post-treatment interval decisions may shape both clinical outcomes and antimicrobial stewardship in bovine respiratory disease protocols.
New research shows haptoglobin rises with BRD development and declines after treatment, offering insight into disease biology and recovery that clinical signs alone might miss.
New survey results detail how veterinarians and producers assess bovine respiratory disease risk and metaphylaxis decisions when cattle fall into the medium-risk category.
A trusted adjuvant can make all the difference in capturing a strong immune response in young calves.
Direct sampling of the lower respiratory tract can sharpen bovine respiratory disease diagnosis, improve case management and support antimicrobial stewardship.
A comprehensive herd-health program is crucial for the management and prevention of bovine respiratory disease.
K-State veterinarian Bob Larson says 3% to 5% of calves suffer from pnemonia each year.
Looking at Mycoplasma Bovis in beef herds including a calf’s environment and vaccination program.
Experts at Kansas State University’s Beef Cattle Institute share guidelines for tracking herd health.
Limiting stress and maintaining a strong relationship with a veterinarian are vital for an Oklahoma rancher’s success in fighting disease issues.
The minute a newborn calf hits the ground, its surrounding environment can impact its future health. A multi-phase study from the University of California-Davis teases out the finer points of maternity pen management.
When dairy farmers think about animals impacted by cold stress, calves are often the first that come to mind. However, it’s important to remember that cold stress doesn’t just affect calves—it can also significantly impact heifers.
Vigilance with vaccination protocols and calf management can help prevent BRD on the dairy.
The study also showed that a bovine H5N1 virus is susceptible to the antiviral drugs favipiravir and baloxavir marboxil (brand name Xofluza) of the polymerase inhibitor class, as well as the neuraminidase inhibitor zanamivir.
Among the mix of technologies, management factors, and strategies to raise healthy calves: genetics. There is growing evidence that calves can inherit the ability to resist calfhood diseases like pneumonia and scours from their parents.
Dr. Brad White is building a multi-disciplinary team to research the issue. The team will sample over 2,400 cattle in Kansas and Texas as part of their work.
