Heat detection is a method used in animal husbandry, particularly in dairy farming and beef cattle production, to identify when a female animal is in estrus, or "heat." This is the period when she is fertile and can conceive. Farmers often look for specific behaviors, such as increased restlessness, vocalization, and mounting behavior, to determine the optimal time for breeding. Various tools and technologies can assist in heat detection, including electronic monitoring devices and visual observation. These methods help improve breeding efficiency and increase the chances of successful pregnancies, ultimately benefiting the overall productivity of the farm.
