Abstract: One variation of a method includes: compiling a corpus of historical biometric data into a set of historical biometric data containers; at a subdermal sensor unit associated with a cow, capturing a set of biometric data and transmitting the set of biometric data to a superficial tag arranged proximal the subdermal sensor unit; at the superficial tag, transmitting the first set of biometric data to an access point accessible by a remote computer system; representing the set of biometric data in a biometric data container; based on proximity of the biometric data container to a cluster of historical biometric data containers, calculating a similarity score between the biometric data container and the cluster of historical biometric data containers; and, in response to the similarity score exceeding a threshold similarity score, mapping a state, associated with historical biometric data containers in the cluster of historical biometric data containers, to the cow.

Abstract: A system includes a subdermal sensor unit and a superficial tag. The subdermal sensor unit is injectable under skin of an ear of an animal and includes: a subdermal housing; a biometric sensor sealed in subdermal housing; and a subdermal short-range wireless transmitter configured to broadcast a set of biometric data captured by the biometric sensor at a first power level via a short-range wireless communication protocol. The superficial tag includes: a tag housing; a wireless communication module configured to receive the set of biometric data broadcast by the subdermal short-range wireless transmitter in the subdermal sensor unit and transmit the set of biometric data to an access point at a second power level, greater than the first power level, via a longer-range wireless communication protocol.
