“During a six month time frame we increased our pregnancy rate by 4%,” says Sarah. “We’re getting more cows pregnant. We’ve been at 62% pregnant and 12% open after 150 days – the number of pregnancies has gone up. Once this system is paid off, it’s paid off. You don’t have to keep buying it – it will save us $17,000 or more every year.” MAJESTIC VIEW DAIRY LLC • 900 COWS • LANCASTER, WI AI24™ CUSTOMER SINCE JANUARY 2010
“People ask us about getting rid of shots and debate other systems out there,” says Amanda. “SCR convinced us that this is the better system and they’re always working with us. The support we get from SCR, Micro and Semex is hard to beat, and we know the battery life is 7-10 years. I wouldn’t want to try anything else.” Sarah Johnsen & Amanda Abing, Majestic View Dairy LLC, Lancaster, WI

How Does It Work?
It’s simple... Let your cows tell you.
{
The ID station and control unit collect activity information on the cows in the herd to determine their normal level of activity. Once this base level has been established, the control unit identifies cows that are displaying above average or below average activity. High or low activity is indicated by a flashing light and detailed information on the control display. Information is recorded and monitored in the neck tag every two hours and stored for 24 hours. When the cow passes under the ID station (at least once in a 24 hour period) the tag is triggered to send the data to the control box. In the case of cows the ID station should be mounted at the exit from the parlor; for heifers mount near their watering stations. Research has shown that the cow’s steps are not the only factor required to accurately indicate estrus. Rubbing movements between cows, body movements and unusual behavior like additional head and neck movements of the cows are also indicators of estrus. The system enables the user to view the activity history of each cow in a graphical display for up to one year.

“The percentage of cows pregnant at vet check before Heatime® was 70%, now they average 83% and the highest (check) has been 91%,” says Case. Simple to operate, the Kasbergens found Heatime® extremely easy to use and implement. “If you know how to use a computer, this is very simple, with simple commands,” says Case.

Don’t Just Take Our Word For It Now, studies from three respected North American Universities are backing up what is being seen in the field. Recently, at the American Dairy Science Association (ADSA) annual meeting held in New Orleans, USA, three separate studies conducted at California Polytechnic State University, University of Guelph and University of Wisconsin-Madison using Semex’s ai24™ Heatime® system were presented, showing the effectiveness of installing activity monitoring systems. Here is a summary of their abstracts as presented at ADSA. California Polytechnic State University, San Luis Obispo, California, USA At California Polytechnic State University, they looked at the impact of installing a Heatime® system with rumination tags (HR-Tags) and integrating into the reproduction protocol at Cal Poly Dairy. They used the system to continuously monitor cow activity and rumination levels over a five-month period. Heatime® was used to flag cows that were suspected to be in heat. Additionally, they used the system to identify animals that need to be checked for sickness due to low activity levels. At the end of the five-month period, the pregnancy rate had increased to 22%, an 8% increase from the start of the study. The study concluded that Heatime® with HR-Tags was an effective tool that helped to increase pregnancy rates at Cal Poly Dairy.
can yield the same pregnancy rates to that of herds relying heavily on timed AI protocols, with no significant difference between the systems. The final results of this study are due to be published this Fall, and will include a much deeper analysis into factors that affect the performance of activity monitoring systems and any cost saving that can be achieved through the reduction of drugs and labor in timed AI protocols. University of Wisconsin-Madison, Madison, Wisconsin, USA The third study was conducted at University of WisconsinMadison. This study looked at how effective the Heatime® system can predict the timing of a breeding. For the study, cows on a large 900-cow commercial Holstein dairy in southwestern Wisconsin, were given an injection of GnRH from 35-49 DIM (Days In Milk), followed by injection of PGF2, seven days later. Forty-eight hours after the PGF injection, cows were monitored for the presence using progesterone testing and ultrasound every eight hours for 120 hours. The trial used 42 cows for the analysis, and found that Heatime® correctly identified whether or not the cow ovulated 88% of the time. They also found that peak activity occurred on average 67 hours after the PGF injection, and cows were subsequently bred approximately 10 hours later. The University of Wisconsin-Madison trial shows that Heatime® can be used as an accurate tool to predict the timing of breeding.
University of Guelph, Guelph, Ontario, Canada A trial at the University of Guelph looked at the effectiveness of activity monitoring in three commercial Holstein dairy herds in Ontario, Canada. The study was conducted over a one year period where the herds were divided in two, with half of the herd being monitored by the Heatime® system. The other half of these herds were primarily bred with a timed AI system. The study utilized 1,060 cows, and recorded 3,235 AI breedings during the study period. The results from this study show that a breeding system using primarily activity monitoring
