I am looking to measure heart rate (variability) in adult dairy cattle. I am looking at the Polar monitors and wondering is anyone has any recommendations for monitors and/or straps
We use star-oddi biologgers, altough they are invasive (a small surgery), they are wonderful, and you get not only the heart rate but ECG variability as well
We've used Polar H7 monitors with a Polar equine belt on calves (study led by Kathryn Proudfoot). There were struggles keeping good contact but they are an option.
