Dry dusty weather increases cattle respiratory disease risk and warning signs
Dry and dusty weather can create serious health risks for cattle, especially during spring when strong winds and dry soils are common. According to Dr. Jake Galbreath, North Dakota State University Extension veterinarian, these conditions can increase the risk of respiratory diseases like pneumonia.
Normally, dust particles are trapped in the upper airway and removed by the body through coughing or swallowing. However, when dust levels are too high, these natural defenses can fail. This can cause irritation and inflammation in the lungs, making cattle more vulnerable to infections.
Calves are at greater risk because their lungs are still developing, and their immune systems are not fully strong. This makes early detection of respiratory issues very important to prevent long-term damage.
“Calves are usually more at risk of developing pneumonia because their lungs have not matured, and their immune systems are not fully developed to fight infection,” said Dr. Galbreath.
Farmers should watch for key warning signs such as watery or inflamed eyes, thick nasal discharge, persistent coughing, and difficulty breathing. Increased breathing rates and unusual stretching of the neck can also indicate problems.
Dust can also lead to additional issues, including pinkeye caused by flies attracted to eye irritation. In some cases, frequent coughing can even cause physical strain.
“While the weather conditions that cause significant dust are out of our control,” said Dr. Galbreath, “producers can take some steps to help with dust and reduce the risk of developing respiratory disease.”
Producers are advised to reduce dust levels whenever possible. Common practices include spraying water around pens and roads, limiting traffic near cattle, and using windbreaks. Providing clean water is essential, as proper hydration helps protect the respiratory system.
Moving cattle to pasture, maintaining proper stocking levels, and ensuring balanced nutrition can also support immune health. Vaccination and veterinary consultation are important for prevention and treatment planning.
Early care, proper management, and preventive steps can help reduce the impact of dusty conditions on cattle health.
