One key thing to look at is herd production and nutrition. The results of this work will confirm if adult or immature fluke are the root of the problem that has been identified.

When coughing is persistent and frequent especially when being moved or at housing and milking. This condition in adult cows often is termed as upper respiratory disease and is often associated with viral infections like IBR RSV Pi3 to name a few.This can often lead to deeper lung infections also where we can have secondary bacterial infections.Then you can get coughing from deeper infections of lung parenchyma (the lungs themselves). O’Sullivan confirmed that fluke problems are currently giving concern on dairy farms, even in the driest parts of the country.“We now take dung samples as a matter of routine and have them assessed from a liver fluke perspective. Video 49 Coughing dairy cows and respiratory disease. What level of coughing is a problem? Lungworms 4. When coughing is persistent and frequent especially when being moved or at housing and milking. While there are some general trends every farm can be slightly different and requires investigation.Firstly anything that irritates the nasal passages, trachea (windpipe) and bronchi can cause coughing. These can be difficult to diagnose because they don’t fully develop into adults (because of life long immunity at lung level) meaning no eggs are produced to pick up on faeces testing.With lungworm, we must also remember that conditions favorable for good grass growth are also the same conditions that many parasites like to spread and develop in.This can be costly and also may lead to resistance in the future. My cut off point or time for farmers to change tactics is when they are dosing cows more than 3 times in the grazing season with eprinomectin. More importantly, if there is other evidence such as sick cows, milk drop etc.Making assumptions is dangerous. It is one way to control lungworm in adult cows but I feel an unsustainable one as we have only one licensed product for lactating dairy cows (Eprinomectin). What happens with lungworm is there are two levels of immunity at the gut where the parasite enters the body and at the lungs. The immunity in the lungs is lifelong while the gut immunity wears off after a while.With reinfection syndrome we have larvae getting to the lungs because of short gut immunity and not developing into adults which causes problems. This is an ongoing challenge some dairy herds face.

Treat the disease, not the symptoms.

Lungworm is predominantly a pasture problem from June onwards. Pneumonia 2. We use cookies to ensure that we give you the best experience on our website, by using this site you agree to our cookie policy Ideally, we want younger animals to develop immunity over time to low levels of lungworm. Vets will be happy to provide the appropriate advice on this issue.” Most respiratory problem can be traced back to poor ventilation in sheds. Add in a tight grazing system (4cm post grazing height) and heavy stocking densities and we certainly have big contributing factors in some farms.At calving time or early summer, it can often be nutritional stress with viral infections for example.

This is why lungworm vaccination has a big role in problem herds.We also have seen reinfection syndrome, this can be complicated. It is the more complicated disease of respiratory disease in adult cows. The symptoms to look out for are cattle walking in circles. Farmers should not automatically assume that coughing cattle, including cows, have a “In some instances this can be the case,” he said. When we see cows coughing at housing or around calving I’m always more suspicious of viral infections.The last number of herd issues with a respiratory disease I have seen have had underlying immune stressors involved. This is why we need to make a diagnosis to make a difference.The type of cough and time of year can give us indications of what might be happening.

“The source of these problems is poorly fermented silage, which can be found close to the surface of silos or in the vicinity of silo walls.” The roblem is these conditions if favorable can mean lungworm levels in pasture can spike quickly. Watch the video above as I explain.Where we see herd incidences of any infectious agent like a respiratory disease. Focusing on lungworm, the cough tends to often be very deep and when no viral/bacterial infections often present without major nasal discharges.Of course, timing can give us indications as well. This is where I have considered and used vaccination where lungworm was a severe issue on farms.Firstly mild wet summers are ideal for lungworm. I have seen many cases of viral disease in dairy herds in May. Good question, of course cows at herd level can give an odd cough. “Once ingested they can travel to the brain, following which meningitis can set in.
