L'invention concerne un système (1) de mesure de la température corporelle d'un animal comprenant : un capteur (100) de température qui est intégré à l'intérieur du corps d'un animal et qui transmet une valeur détectée par rapport à la température ambiante; et un ordinateur (200) personnel servant de dispositif de traitement de données qui utilise une valeur (500) de température corporelle de référence obtenue par la prise d'une mesure réelle de la température d'un site d'intérêt dans l'animal à l'aide d'un thermomètre différent du capteur (100) de température, pour convertir la valeur détectée reçue du capteur (100) de température en une valeur de température convertie. L'ordinateur (200) personnel peut acquérir la valeur (500) de température corporelle de référence, représentant une valeur de température obtenue par la prise d'une mesure réelle de la température du site d'intérêt dans l'animal, dans un état dans lequel le capteur (100) de température est intégré dans le corps de l'animal, calculer un paramètre de conversion sur base de la valeur (500) de température corporelle de référence et d'une première valeur détectée mesurée à l'aide du capteur (100) de température environ au moment de la mesure de la valeur (500) de température corporelle de référence, recevoir une deuxième valeur détectée du capteur (100) de température et convertir la deuxième valeur détectée en valeur de température convertie à l'aide du paramètre de conversion.
