Solution Overview

Problem

Current systems and methods for estrus detection in dairy livestock are inadequate, leading to suboptimal reproductive efficiency and milk output in dairy farming operations.

Innovation Solution

A method that uses real-time location tracking and analysis of movement parameters within a free stall pen to determine whether dairy livestock are in estrus, incorporating identification devices and a controller to process location data and calculate heat indices for estrus detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If real-time location tracking and movement parameter analysis are implemented for estrus detection, then reproductive efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvereproductive efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual observation and mechanical estrus detection methods with automated electronic location tracking and movement analysis. Transponders and readers automatically capture location data, and a processor automatically analyzes movement parameters to detect estrus, eliminating the need for manual herd monitoring and reducing system complexity despite the introduction of electronic components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables dairy livestock to self-report their location and movement status through implanted transponders that automatically communicate with readers. The animals themselves provide the data needed for estrus detection without requiring external intervention, thereby improving reproductive efficiency while keeping the system relatively simple as it leverages the animals' own movements as the detection mechanism.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automated estrus detection based on location data is implemented, then labor requirements are reduced, but manufacturing precision is required for accurate movement parameter calculation

Engineering Contradiction:
Improvelabor requirementsVSAvoidmovement parameter calculation accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system performs preliminary actions by continuously collecting and storing location data at predetermined intervals before estrus detection is needed. This pre-captured location information is then used to calculate movement parameters when required, reducing the need for real-time manual intervention while ensuring accurate calculations through pre-processed, high-precision location data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where calculated movement parameters are continuously monitored and compared against established thresholds. When movement patterns indicate estrus, the system provides feedback through alerts or notifications, enabling automated decision-making without requiring high-precision manual calculation, thereby reducing labor requirements while maintaining detection accuracy.

Inventive Principle:
Principle #23Feedback

AI summary

A method for estrus detection includes storing location information associated with a dairy livestock. This information includes coordinate locations of the dairy livestock within a free stall pen at each of a plurality of times during a time period including a first time and a second time. The coordinate locations comprise at least a first (X, Y, Z) location of the dairy livestock at the first time and a second (X, Y, Z) location of the dairy livestock at the second time. The method further includes determining, based on at least the first and second (X, Y, Z) locations, a turn index parameter indicating a number of times the dairy livestock reverses directions during the time period. The method further includes determining whether the 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.
