The invention relates to the field of
animal breeding and animal
medicine, and provides a method and a device for measuring the core body temperature of
livestock. According to the measuring method, in accordance with a physiological structure of the measured
livestock, a temperature sensor is coupled with the
body surface close to the core body temperature, a
heat flux conduction formula is utilized, the
temperature gradient of
artificial materials can be calculated through
heat resistance, the
heat resistance of a measured position of body tissues is derived, and the core body temperature is deduced in an inversion way through the measured
body surface temperature. Before the long-time use, the correction is carried out through measured values of the rectal temperature. The device comprises a
heat transfer layer, an outside heat
insulation layer and three temperature sensors, wherein the heat
conductivity and the thickness of the
heat transfer layer are known, the temperature measuring parameters of the three temperature sensors are very close through tests, and the temperature sensors are used for respectively measuring the surface temperature of the
skin coupling position, the surface temperature outside the
heat transfer layer and the surface temperature outside the heat
insulation layer. When the method and the device provided by the invention are used, the long-period, continuous and dynamic core
body temperature measurement on the
livestock can be realized.
