System and method for health monitoring using real-time location

摘要

A method for health monitoring comprises electronically receiving location information for a dairy livestock that is generated by a plurality of identification devices positioned in a pen that operate in conjunction with a tag worn by the dairy livestock. The method stores the location information associated with the dairy livestock, the location information comprising a location of the dairy livestock within the pen at each of a plurality of times during a first time period. The method determines, based on at least a portion of the stored location information, a turn index parameter indicating a number of times the particular dairy livestock reverses direction during the first time period. The method determines whether the particular dairy livestock is likely to be in estrus based at least in part upon whether the determined turn index parameter is in excess of a baseline turn index parameter by more than a predefined amount.

主权项

1. A method for health monitoring, comprising:
electronically receiving location information associated with a dairy livestock, the location information generated by a plurality of identification devices positioned in a pen that operate in conjunction with a tag worn by the dairy livestock; storing the location information associated with the dairy livestock, the location information comprising a location of the dairy livestock within the pen at each of a plurality of times during a first time period; determining, based on at least a portion of the stored location information, a turn index parameter indicating a number of times the particular dairy livestock reverses direction during the first time period, wherein the particular dairy livestock reverses direction when a difference in angular direction of the dairy livestock changes by less than ninety degrees or more than two-hundred-seventy degrees; and determining whether the particular dairy livestock is likely to be in estrus based at least in part upon whether the determined turn index parameter is in excess of a baseline turn index parameter by more than a predefined amount; wherein the location information comprises an (X,Y,Z) coordinate.
