Researchers from the University of Guelph recently finished a field trial for a prototype of a new commercial fertility and ovulation detection system being developed by Pheromone Sciences. It is based on the company’s technology that is designed and government-approved for human use.

The prototype uses specially designed biosensors resting on the cows’ neck to identify hormone-related changes indicative of oncoming estrus. The data from this study indicate that the system could predict estrus in dairy cows 60 percent of the time.

Researchers say the results from these preliminary tests compare favorably with current technologies available; however, don’t expect this new system to hit the market just yet. Design changes are under way to help improve the efficiency of the product’s performance. And additional clinical tests are required to ensure the repeatability of the results.
