Description
Devaraj Sankarganesh and colleagues update the state of estrus detection in dairy cattle in a 2026 review. Catching the brief fertile window accurately is essential because most dairy breeding uses artificial insemination. Missed or mistimed detection is a major drag on reproductive efficiency, and high-yielding cows often show only faint signs of heat.
The review covers hormone programs that synchronize cycles so the fertile window arrives on schedule. It then turns to sensor systems, from activity monitors worn on the neck or leg to implanted devices, and to chemical sensors that read biomarkers in milk or breath. A newer strand uses artificial intelligence on behavior data gathered by those sensors. The authors weigh each method's accuracy, practicality, and cost for farmers. They close by flagging experimental technologies that could sharpen detection further once validated on real farms.
