Preventing Respiratory Diseases in Calves
Bovine Respiratory Disease (BRD) can negatively impact a cattle operation – both dairy and beef – in big ways. As the leading cause of morbidity in dairy calves, it’s something we hear quite a bit about from dairy farmer customers who have calves year-round. That’s why we’re sharing some insights from disease experts about treatment and prevention options so you have all the right information for how to care for your animals, especially the calves.
What is Bovine Respiratory Disease (BRD)?
If you’ve heard of “shipping fever” you’ve heard of BRD. Whatever you call it, the disease can affect cattle at any time or age, but young animals are more susceptible under stressful conditions. Multiple culprits cause BRD, including bacteria, lacking nutrition, even environmental issues such as cold weather, overcrowding, weaning and more.The following viruses are also leading causes for BRD:
- Pneumonia
- Parainfluenza (PI3)
- Bovine Respiratory Syncytial Virus (BRSV)
- Infectious Bovine Rhinotracheitis (IBR)
- Bovine Viral Diarrhea (BVD)
BRD Symptoms to Watch For
If you suspect your animal has a respiratory disease, the BRD symptoms can show up as depression (droopy ears and a lower head position), reduced appetite, unusual respiration with heavy breathing and/or flared nostrils (even a regular cough) and a fever above 104°F. Pay close attention to these main symptoms during the 30-60 day window after feedlot arrival as it appears many cases start there.Veterinarians advocate for lung ultrasounds as the best way to diagnose early cases of BRD. You may also consider getting properly trained by your vet to do the ultrasounds yourself in the future.
How Long Does Bovine Respiratory Disease Last?
The symptoms mentioned above can last for two weeks or more, depending on how far along the disease was when first discovered. Experts say early diagnosis and treatment is key to tackling BRD, and with calves, it’s even more important to watch them closely in their early days for any signs of illness. Quick action can avoid permanent lung damage and save the operation from bearing long-term production losses like lower weight and later breeding. In fact, Beef Magazine says almost 20% of cow-calf operations experience nursing-calf pneumonia, and it’s the leading cause of death for calves 3 weeks of age and older.If you need BRD treatment products, your vet may prescribe one of the following which our pharmacy can fill:
- Cefenil RTU for Cattle & Swine Rx
- Excenel RTU EZ Suspension Rx
- Excede Sterile Suspension for Cattle Rx
- Polyflex Injectable Rx
BRD Prevention is Key
Stress on calves is inevitable during transport, weaning, etc., so many producers are taking the prevention approach to avoid BRD proactively. In our spring vaccination planning article, we talked about how vaccines are part of a preventative health management strategy that’s best designed in consultation with your vet. That article listed several vaccine options that can help protect against BRD and the viruses that cause it; the vaccines include:Another preventative product, Zoetis’ NEW Protivity Cattle Vaccine, specifically works to protect against Mycoplasma bovis, which is one of several bacteria that can cause BRD. If your herd has tested positive for mycoplasma bovis bacteria in the past, you may want to consider this vaccine for healthy cattle, 1 week of age or older. Please read all label instructions and discuss questions with your vet.
