- fever of over 40°C (>104°F)
- difficulty breathing occurred to varying degrees.
- nasal discharge.
- varying degrees of depression.
- diminished or no appetite (“off feed”)
- rapid, shallow breathing.
- coughing.
What is the cause of BRD in cattle?
It usually is caused by a variety of pathogens, both viral (Bovine Respiratory Syncytial Virus (BRSV), ParaInfluenza 3 (PI3), Adenovirus, Bovine Viral Diarrhea Virus (BVDV), and Infectious Bovine Rhinotracheitis (IBR)) and bacterial (Pasteurella multocida, Mannheimia haemolytica, Histophilus somni, Mycoplasma bovis).
Is BRD contagious?
This would suggest that, not only is BRD not contagious, but that risk factors would be hard to identify or may not be important, at least in that study population. Another study found cases of respiratory disease often clustered according to truck (a proxy for source) and less frequently by pen (83).
How is BRD diagnosed?
Diagnosis. A presumptive diagnosis of BRD is often made based on signs, the physical exam and disease incidence in the herd. Early detection is important so affected calves can be isolated in the sick pen.
How is BRD spread?
BRD is spread by nasal discharge into the air, so an infected animal can spread the disease to healthy calves inside the same barn, or to nearby calves in open areas.
How long does pneumonia last in cattle?
Coughing is frequent with pneumonia caused by parasites that also occurs in pastured cattle. Most fatalities occur during the first two days and cattle that survive start to get better quite quickly after that with full recovery in about 10 days without treatment.
Is BRD shipping fever?
Bovine respiratory disease (BRD) costs beef producers up to $240 a head. Annually, it accounts for $1 billion in feedlot losses due to loss of production, increased labor expenses, medication costs and death. Also known as shipping fever, BRD is behind about 75% of illness and up to 70% of cattle deaths in feedlots.
What causes calf pneumonia?
Multiple infections cause pneumonia. The most common viruses that cause pneumonia in calves are infectious bovine rhinotracheitis (IBR), parainfluenza-3 (PI3), bovine respiratory disease (BVD) and bovine respiratory syncytial virus (BRSV). The main bacterial causes are mycoplasma, pasteurella and haemophilus.
Can a cow recover from pneumonia without antibiotics?
Most fatalities occur during the first two days and cattle that survive start to get better quite quickly after that with full recovery in about 10 days without treatment.
What diseases are common in feedlot cattle?

Mastitis is the most deadly and costly bacterial disease of dairy cattle. Cattle Diseases: Calf Scour. Pink Eye in cattle. Bovine Viral Diarrhea (BVD) in Cattle. Mad Cow Diseases. Footrot in Cattle.
What is Pi disease in cattle?
The PI cattle that do survive ill-thrift are susceptible to mucosal disease. Mucosal disease only develops in PI animals and is invariably fatal. Disease results when a PI animal is superinfected with a cytopathic biotype arising from mutation of the non-cytopathic strain of BVDV already circulating in that animal.
What is backgrounding cattle mean?
Backgrounding is an intermediate stage sometimes used in cattle production which begins after weaning and ends upon placement in a feedlot .
What is Pi test for cattle?
Testing for BVD-PI cattle is different than testing for many other diseases because PI status stays the same throughout the animal’s life. Thus, BVD-PI testing is usually done only once. Meet with your veterinarian to determine your BVD goals and exposure risk. Various testing strategies for whole herd testing exist.
