1. A livestock monitoring method comprising:
accessing a motion sensor signal generated by an animal bolus sensor located within the reticulum or rumen of a non-human mammal, the motion sensor signal comprising a rotational component describing a rotational motion of the sensor within an animal and a linear component describing a linear movement of the sensor within the animal;
identifying an animal respiration signal with the rotational component of the motion sensor signal;
generating a respiration-corrected linear component through use of the linear component of the motion sensor signal and the animal respiration signal; and
detecting an animal heart signal from the respiration-corrected linear component.
