Call us. Bovine Respiratory Disease: Catch It Before It Costs You Bovine Respiratory Disease (BRD) is one of the most common, and expensive, health challenges on dairy farms. Often referred to as pneumonia, BRD can hit calves hard and fast. It's not caused by a single bug. BRD is a complex mix of stress, viruses and bacteria that together compromise the lungs. Even calves that appear healthy can deteriorate quickly. Typical signs include coughing, fever and laboured breathing. Calves may go off their feed, lie down more than usual, breathe faster or simply look dull. The problem is timing - by the time these symptoms are obvious, the disease is often well established. Early identification and prompt treatment are critical to limiting long-term damage and losses. Why BRD Hits the Bottom Line BRD isn't just a health issue, it's also a profitability issue. Calves that struggle with pneumonia rarely catch up completely. Poor growth at an early age can impact future production and lifetime performance. That's why prevention and early action matter. Cattle have relatively small lung capacity for their body size, so protecting respiratory health from a young age is essential. When BRD takes hold, it can mean reduced milk yield later on and higher vet costs down the track. Those losses add up quickly. Why Visual Checks Aren't Enough Relying on what you can see has its limits. Coughing, nasal discharge or a calf falling behind the mob can all signal BRD. But cattle are prey animals - they instinctively mask signs of weakness. By the time you notice something's off, you may already be behind. This is where monitoring technology changes the game. Continuous tracking of behaviour and activity highlights subtle shifts long before clinical signs are obvious. Smarter Calf Monitoring with CowManager CowManager's Youngstock module is built specifically to monitor calf health. Using a single ear sensor, it continuously tracks eating, rumination, behaviour and activity levels - the signals that drive every alert - while ear temperature is recorded alongside as supporting validation data. When a change is flagged, temperature adds extra confidence to what the behaviour data is already showing. If a health alert flags a change, that's the moment to bring your vet in - not after the calf is visibly sick, thereby picking up on illnesses which may be linked to the BRD complex early. CowManager gives your vet free access to the same data you're seeing, so they're working from the same picture, not starting from scratch. Earlier intervention means treating before the disease is entrenched - which matters, because BRD damage is often irreversible once established. Healthier calves develop into stronger, more productive cows, protecting your herd and your margins. The same sensor, active from three weeks of age or 50kg liveweight, continues working as calves transition into the milking herd. CowManager's Health solution provides lifetime monitoring, allowing you to compare individual and group performance, analyse trends and make informed management decisions at every stage. Combine strong management with real-time monitoring, and you give BRD far less chance to take hold and cause lifetime damage. Protecting calves from respiratory disease isn't just about animal welfare - it's about safeguarding the long-term performance and profitability of your New Zealand dairy operation.
