Over the past year, the Philippen family’s dairy farm in Heinsberg has invested in a heat detection system with built-in health monitoring. How has fertility management improved since?
The Philippen dairy farm in Heinsberg, south-west Germany on the edge of the Ruhr valley, has undergone remarkable development in the last 13 years. In 2005, the Philippen family expanded from 40 tethered cows at the time to 120 cows and set up a new barn in open pasture 11 km from the old site. When the family’s son and current farm manager, Christoph Philippen, joined the company in 2014, the family expanded the barn to what is now 200 cows. The herd’s current milk yield is 10,400 kg on average.
Growth requires digital technology
To meet the increasing growth-related demands on management, in June 2017 the farm invested in a heat detection system with built-in health monitoring to optimise farm fertility management and more effectively prevent health problems. The Semex AI24 system with Nedap technology is attached to the cow’s collar in the form of so-called Smarttags that contain sensors and measure not only activity (movement and registration of oestrus signals) but also monitor health based on eating and rumination habits.
The system receives data on individual animals via the antenna in the barn. Twice a day, in the morning before and after milking, the Philippen family monitors in the system (either via computer or smartphone) which cows are on heat based on the activity curve. After that, an insemination technician from Rinder-Union West eG (RUW) comes in the morning and inseminates two to three animals a day.
Farm manager Christoph Philippen:
“The system has saved us a lot of man hours since it was introduced because we can now identify cows on heat better and sooner than before.”
The Semex AI24 system is linked to the herd management programme of the company Uniform Agri. Periodic synchronisations occur at regular intervals. According to the manufacturer, the system is also compatible with all other conventional herd management programmes (e.g. Herde, Dairy Plan C 21 and DairyComp). The range of the antenna in the barn is around 75 meter. With the antenna, the construction of the barn matters more than the number of cows. The system can also be used when putting out to pasture for the grazing land using a larger outdoor antenna. The service life of the batteries and smart tags is eight to ten years depending on the manufacturer.
The Philippen family farm last expanded its production pen by 80 places in 2014 and also built a new calf pen (left).
Increase the heat detection rate – problems become more quickly recognisable
Before the company invested in the system, heat detection was done visually by regular observation in the barn, which required a lot of time and close monitoring. “We would sometimes miss a cow or spot it too late, so we had to inject more often,” says the young farm manager.
Thanks to the new heat management system, the Philippen family has been able to increase the heat detection rate (HTR) from 56 percent to 71 percent. The inter-calving period (ICP) has also been reduced from 384 to 373 days. The voluntary waiting period (VWP) is currently 60 days. However, the farm manager is considering increasing it again by around ten days in future so that high-yielding cows can be milked for longer.
Through simultaneous health monitoring based on eating and rumination habits, udder diseases, for instance, can be detected at an early stage because feed intake or rumination activity usually decreases. “Cows that eat less before calving are often seen as problem cows after calving,” says Philippen.
Farm manager Christoph Philippen:
“Now we can react faster. In the past, we often didn’t detect problems like this until two or three days later.”
The calf pen, built in 2014, is divided into three groups: the first two groups are located on the automatic feeder, and the final one is already set down.
For the investment in the heat detection system with health monitoring, the Philippe family spent around 100 Euros per cow. Overall, the heat detection rate has increased significantly so far, and the inter-calving age and lactation days have declined. In addition, the cows are not as fat at insemination as before because insemination takes place sooner. Injection is also less often required because oestrus is detected faster.
