Sow Morphology Sensor for Automated Feed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling the amount of feed supplied to sows rely on visual observation by operators, which is inefficient and labor-intensive, especially when managing large numbers of gestational or lactating sows.
Innovation Solution
A method and apparatus that utilize a non-contact sensor to recognize morphological data of each sow, determining weight management information such as body condition score, and automatically controlling the feed supply based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If visual observation by operator is used to control feed supply, then feeding control can be performed, but labor intensity increases and productivity decreases when managing large numbers of sows
Solution Approach 1:
The patent replaces the mechanical/visual observation system with an automated sensor-based system. Sensors automatically capture morphological data of sows, and the controller processes this data to determine feed supply amounts, eliminating the need for manual visual observation and significantly reducing labor intensity while improving productivity
Solution Approach 2:
The system enables self-service by having sensors automatically monitor sow morphology and the controller automatically determine and execute feed supply decisions without human intervention. The system serves itself by continuously monitoring and adjusting feed based on detected morphological changes
2Reliability
If manual visual observation is used to monitor body condition score, then feeding control is possible, but working time increases significantly
Solution Approach 1:
The sensor system operates continuously to monitor sow morphology without interruption, providing continuous data for feed control decisions. This eliminates the discontinuous nature of manual observation and ensures that feeding control is always based on current, accurate morphological data
Solution Approach 2:
The patent replaces time-consuming manual visual observation with automated sensors that continuously capture morphological data. The controller processes this data to determine accurate feed supply amounts, maintaining high reliability while significantly reducing the time required for monitoring and control
3Productivity
If operator visually observes each sow individually, then feeding control can be performed, but device complexity increases due to need for multiple sensors and systems
Solution Approach 1:
The patent employs multi-functional sensors that can detect various morphological parameters (body condition score, back fat thickness, body weight) using a single device. This universal approach allows the system to manage multiple sows effectively without requiring separate specialized sensors for each parameter, thereby controlling system complexity while maintaining high productivity
Data Source
AI summary
A feed supply amount control method for sows and an apparatus therefor are disclosed. A feed supply control device recognizes morphological data of a sow through a sensor, determines a weight management information including a body condition score of the sow based on the morphological data, and controls the amount of feed to be supplied to the sow according to the weight management information.
