Respiratory Health

Don’t Let Bovine Respiratory Disease Go After Your Calves. Or Your Bottom Line

Bovine respiratory disease (BRD) can be frustrating for beef producers for a number of reasons. The multitude of factors that contribute to the disease can make it difficult to prevent or manage. And BRD can lead to significant economic losses:

  • It’s the No. 1 cause of mortality in weaned calves1
  • Most BRD deaths occur shortly after feedlot arrival or within 45 days2,3
  • It costs producers $900 million in losses each year from death, reduced feed efficiency and treatment costs4


Help protect your investment by working with your veterinarian on a BRD prevention protocol, and stay current on the most recent BRD information:

Bovine Respiratory Disease (BRD)

What is bovine respiratory disease (BRD)?

  • Any disease of the upper and/or lower respiratory tracts
  • Also known as shipping fever because it’s often associated with transport


Cattle affected

  • Most commonly occurs in weaned beef cattle as they move to the feedlot
  • Preweaned calves (enzootic calf pneumonia)


Disease development

  • A multifactorial etiology that may include viruses, bacteria, host immunity, environmental stressors, nutrition and more
  • Typically, stress associated with transportation, commingling, weaning and other factors predisposes the animal to infection
  • The lining of the respiratory tract may be damaged by viruses such as:
    • Bovine viral diarrhea virus (BVDV) Types 1a, 1b and 2
    • Infectious bovine rhinotracheitis (IBR) caused by bovine herpesvirus-1 (BHV-1)
    • Bovine respiratory syncytial virus (BRSV)
    • Parainfluenza 3 (Pl3) virus
  • Viral damage opens the door for bacteria to invade the lungs:
    • Mannheimia haemolytica
    • Pasteurella multocida
    • Histophilus somni
    • Mycoplasma bovis


Clinical signs

  • Severity of signs can vary, depending on the organism(s) involved, but may include:
    • Labored breathing
    • Nasal discharge
    • Coughing
    • Reduced food and water intake
    • Fever, depression
    • Reluctance to move


Diagnosis

  • Physical examination
  • Culture and antibiotic sensitivity, tissue analysis or advanced diagnostics


Treatment

  • Identify and treat sick calves early for best outcomes
  • Work with your veterinarian to choose the right antibiotic
  • Monitor outcomes and refine protocols with your veterinarian


Prevention

  • Precondition calves before marketing, including:
    • Vaccinating calves to help build immunity
  • Vaccinate the dam to help her produce good-quality colostrum
  • Metaphylaxis, or mass administration of antibiotics to at-risk calves, may help reduce the number of bacterial organisms present, but will have no effect on viruses

Important Safety Information

ZACTRAN IMPORTANT SAFETY INFORMATION: For use in cattle only. Do not treat cattle within 35 days of slaughter. Because a discard time in milk has not been established, do not use in female dairy cattle 20 months of age or older, or in calves to be processed for veal. The effects of ZACTRAN on bovine reproductive performance, pregnancy and lactation have not been determined. Subcutaneous injection may cause a transient local tissue reaction in some cattle that may result in trim loss of edible tissues at slaughter. NOT FOR USE IN HUMANS. KEEP OUT OF REACH OF CHILDREN.

Successful BVDV Prevention Strategies Focus on Type 1b

Thirty years ago, the majority of bovine viral diarrhea virus (BVDV) cases were caused by Type 1a. Now Type 1b has emerged as the most prevalent subgenotype of BVDV in the United States, accounting for roughly 70% of reported cases.
