System and method for estrus detection using real-time location

摘要

In certain embodiments, a method for estrus detection includes storing location information associated with a dairy livestock. The stored location information includes a coordinate location of the dairy livestock within a free stall pen at each of a plurality of times during a time period. The method further includes determining, based on at least a portion of the stored location information, one or more movement parameters associated with the dairy livestock. The method further includes determining, based on one or more movement parameters associated with the dairy livestock, whether the dairy livestock is likely to be in estrus.

主权项

1. A system for estrus detection, comprising:
a plurality of identification devices positioned in a free stall pen; one or more tags attachable to each of a plurality of dairy livestock in the free stall pen; one or more memory modules that stores location information obtained from one or more of the plurality of identification devices and the one or more tags, the location information associated with a particular dairy livestock from the plurality of dairy livestock and comprising a plurality of coordinate locations of the particular dairy livestock within the free stall pen at each of a plurality of times during a time period including a first time and a second time, wherein the plurality of coordinate locations comprises at least a first (X, Y, Z) location of the particular dairy livestock at the first time and a second (X, Y, Z) location of the particular dairy livestock at the second time; and one or more processors that:
determine, based on at least the first and second (X, Y, Z) locations, a turn index parameter indicating a number of times the particular dairy livestock reverses directions during the time period; anddetermine 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 first predefined amount.
