Raising healthy calves requires a balance of observation, experience, and timing. The challenge being calves instinctively hide signs of illness, because showing weakness as prey animals can make them appear vulnerable. By the time a calf shows the slightest clinical sign, the disease or infection may already be affecting health and performance.
The goal of electronic calf monitoring is not to treat more calves, but to identify behavioral changes earlier, understand what those changes mean, and make better decisions when intervention is needed. This is where technology and the skill of the caregiver come together.
We cannot have eyes on calves 24 hours a day. In many operations, the amount of direct observation each calf receives may only be 10–15 minutes per day. Within that short window, caregivers are managing feeding, cleaning, treatments, and many other responsibilities. Catching subtle behavioral changes consistently can be difficult, especially as herd sizes continue to grow.
Every calf has its own normal. Activity patterns, resting behavior, drinking behavior, and rumination development change as calves grow. For example, calves naturally spend a large portion of their day lying down, often 70–80%, but what matters is when there is a change from that individual calf’s normal behavior.
CowManager helps bridge the gap between visual observations by continuously monitoring calf behavior, identifying changes that may otherwise be missed, and notifying you of changes with a health alert. Instead of relying only on visual observations during scheduled checks, CowManager gives caregivers additional information to help prioritize which calves need attention. The value is not simply in receiving an alert. The value comes from asking: Why is this calf behaving differently, and what action should we take?
By identifying changes earlier, farms can focus their time and resources where they matter most. This can improve labor efficiency, help identify subclinical disease before it becomes a larger issue, improve treatment success, and support better calf outcomes.
Calf monitoring and early detection can be especially valuable during weaning transition. Calves that experience health challenges during this period may struggle to maintain growth and performance. Having insight into individual calf progress allows caregivers to make more informed decisions and provide support when needed.
Ultimately, calf monitoring is about combining experience with data to better understand each calf as an individual. That understanding helps producers become better caregivers by making more informed decisions about calf health, growth, and development. By improving visibility into calf behavior, farms can spend less time searching for problems and more time focusing on improving health, growth, and future performance.
The future of herd profitability starts with the next generation. Better calf monitoring with CowManager, today, helps build stronger cows for tomorrow.
