At Whiteheathfield Farm, dairy farmer Adrian Cole has spent the last 16 months using the Datamars heat and health detection system, and the impact on his herd management has been significant. From sharper breeding decisions to faster identification of health issues, the Active Tag smart farming solution has become an essential part of Adrian’s daily routine.
Adrian explains that the shift to a smart farming approach has been one of the most valuable changes he has made to his dairy farm. The collars give him reliable, real time information on heat activity and early signs of illness, allowing him to act sooner and work more efficiently throughout the year.
“I would be lost without the system now. It has given me so much more time to focus on important jobs with the cows and also the family at home. It means I can afford to take a day off the farm with my wife and children without missing any heats.”
More Accurate Heat Detection and Better Breeding Decisions
Before adopting Datamars Active Tag, Adrian relied on traditional tail paint and heat patches. This made heat detection labour intensive and often less accurate, especially during busy periods. With the Active Tag system, he now receives clear heat alerts that indicate the standing heat and pinpoint the optimal time for AI.
This confidence has transformed breeding across the herd.
Adrian explains
“Before I had this system, I did not have the confidence to use expensive sexed semen and was a flying herd. I am now breeding most of my replacements from my cows, around eighty percent compared to a much smaller figure. This is down to the confidence I have in serving animals based on their AI window in the Datamars system and using good quality sexed bulls.”
The improvements in heat and health detection have also helped tighten the calving interval. Adrian’s interval had been sitting well above 400 days, but with accurate alerts and better reproductive management, he has brought this down to 380 days. This change alone has helped increase milk yield, boosting the milk cheque and creating a more productive calving pattern.
Early Health Detection that Protects Cows and Saves Time
For Adrian, one of the most valuable parts of the Datamars smart farming solution is its ability to flag subtle changes in cow behaviour long before visible symptoms appear. The collars regularly catch early signs of mastitis or lameness, often before he or his team notice anything during daily checks.
“Generally the health issues are catching early cases of mastitis or lameness before myself or the staff have noticed, which means we can act quickly to avoid any issues with those individual animals. This helps me communicate with my workers and relief milkers to make sure these cows are given the extra TLC they need.”
This proactive approach has improved herd welfare and reduced the time and cost associated with treating advanced health problems. It has also made communication on the farm clearer, allowing everyone to work with the same accurate information.
Trusted Reproductive Insights with Real Time Data
Adrian has grown so confident in the system’s accuracy that he can now predict with strong certainty whether a cow is in calf based on her behaviour patterns after service.
“I would be confident enough from the system to be able to say if a cow has held to a straw of semen if she has not come back on the bulling list by forty days from the last service.”
While Whiteheathfield Farm still completes monthly herd health visits, these appointments are now faster and more efficient because Adrian arrives already informed by reliable data from the Active Tag system.
A Smart Farming Approach that Supports Work Life Balance
Like many dairy farmers, Adrian faces the daily challenge of balancing farm work with family life. With accurate heat and health detection working quietly in the background, he has gained peace of mind and the freedom to step away from the farm when needed.
Not only has the system improved breeding results and herd health, it has also supported a more sustainable way of working. Adrian now has the time and confidence to focus on the future of his farm rather than spending hours chasing heats and checking cows manually.
Smart Farming That Delivers for Dairy Farms
Adrian’s experience at Whiteheathfield Farm highlights how heat and health detection technology can transform efficiency, herd welfare and breeding outcomes. The Datamars Active Tag system demonstrates how smart farming solutions can deliver measurable improvements in milk production, livestock health and daily workflow.
For dairy farms looking for a reliable and accurate dairy solution that supports better decision making, Datamars provides a powerful tool that works around the clock.
