Health and Growth Performance of High-Risk Cattle Treated with Nuflor or Draxxin
In the fall of 2006, a randomized, blinded clinical trial was performed at a commercial feedyard in Nebraska. In a treatment study, a total of 555 high-risk, male beef cattle were treated with either NUFLOR (florfenicol) at 40/mg/kg or Draxxin (tulathromycin) at 2.5 mg/kg after developing respiratory disease.
Managing Respiratory Diseases in the Herd
Year in and year out, diseases of the respiratory system are a major cause of illness and death in cattle from six weeks to two years of age, says Dr. Donald Montgomery, director of the Wyoming State Veterinary Laboratory.
K-State researches bovine respiratory disease
Over the years, advances in biological, pharmaceutical and management systems have failed to eliminate the most common cause of post-weaning disease in cattle, Bovine Respiratory Disease Complex.
Thinking beyond the shots
Kansas State University veterinarian Dan Thompson outlines an “evidence-based approach” to starting calves during last month’s K-State Beef Stocker Field Day.
Virus enzymes could promote human, animal
Could viruses be good for you? Scientists with the USDA’s Agricultural Research Service have shown that enzymes from bacteria-infecting viruses known as phages could have beneficial applications for human and animal health.
BRD Symposium summaries
The 2009 BRD Symposium was held Aug. 5-6, with more than 15 speakers on bovine respiratory disease trends, prevention and control. Drovers and Bovine Veterinarian have summaries available online.
Disease control on organic and natural cattle operations
As interest grows in certified-organic or natural production, Hubert J. Karreman, VMD, Narvon, Penn., outlined ways veterinarians can help their clients protect animal health while complying with program specifications.
Comparing testing methods for BRD-related viruses
Researchers compared PCR nasal swabs with cell-culture procedures in testing for bovine respiratory syncytial virus, bovine coronavirus and bovine diarrhea virus.
The 4th U.S. BVDV Symposium, Impact on Virulence, Host Range and Control, was held in late January. Drovers and Bovine Veterinarian compiled summaries of all the presentations and make them available here.
BRD prevention, treatment and immunology
Boosting lung defenses can include things like low-stress handling and timely use of respiratory vaccines. Dozens of vaccines are available for use in cattle but you can’t get “immunity in a bottle” without strategic timing and proper management.
BRD pathogenesis and clinical signs
There are various clinical signs feedlot cowboys use to assess sick cattle, ranging from snotty noses, depression and anorexia. But taking a closer look at those clinical disease expressions and understanding their subtle differences can give you a better clue as to what’s happening in the animal.
Derailing the lung’s defenses
There’s no doubt that calves coming into the feedlot are undergoing a big dietary and lifestyle change. Epidemiologically, diet has often been associated with respiratory disease in cattle.
Arrival situations: Controlling what we can
A popular prayer asks for “the serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference.”
