Don't Let Bovine Respiratory Disease Go After Your Cattle. Or Your Bottom Line.

Bovine respiratory disease (BRD) can be frustrating for dairy 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:

  • In nationwide surveys, it's estimated that 12% to 16% of preweaned calves and 6% to 11% of weaned calves experience BRD1
  • It's the No. 1 cause of mortality in preweaned and weaned dairy calves, with death losses of 2.3% and 1.5%, respectively2
  • Respiratory problems account for approximately 11.3% of adult dairy cow deaths3

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 


    Cattle affected

    • Most commonly occurs in preweaned and weaned dairy calves (enzootic calf pneumonia)


    Disease development

    • A multifactorial etiology that may include viruses, bacteria, host immunity, environmental stressors, nutrition and more
    • Typically, stress and other factors predispose 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)
      • Parainfluenza3 (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 the dam to help her produce good-quality colostrum
      • Vaccinating calves to help build immunity

BIO-MYCIN IMPORTANT SAFETY INFORMATION: When administered to cattle, muscle discoloration may necessitate trimming of the injection site(s) and surrounding tissues during the dressing procedure. Discontinue treatment at least 28 days prior to slaughter. Milk taken from animals during treatment and for 96 hours after the last treatment must not be used for food. Rapid intravenous administration may result in animal collapse. Product should be administered intravenously slowly over a period of at least 5 minutes. Exceeding labeled dose or more than 10mL per site may result in antibiotic residues beyond the withdrawal period. Reported adverse reactions may be attributed to anaphylaxis or to cardiovascular collapse of unknown cause.

POLYFLEX RESIDUE WARNING: Do not treat cattle for more than 7 days. Milk from treated cows must not be used for food during treatment, and for 48 hours (4 milkings) after the last treatment. Cattle must not be slaughtered for food during treatment, and for 144 hours (6 days) after the last treatment.

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.

Create a Smoother Transportation Experience for Your Dairy Calves 

Stress from transportation can compromise the immune system and make calves susceptible to bovine respiratory disease (BRD) and bovine viral diarrhea virus (BVDV). A transportation plan is paramount to avoiding these disease disasters.
