Farrowing Pen With Moveable Barriers For Piglet Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Farrowing pens often compromise between providing sufficient space for sows and ensuring the safety and well-being of piglets, as sows may crush piglets due to limited space or accidentally harm stockmen attempting to assist, while also requiring adequate heating for piglet survival.
Innovation Solution
A farrowing pen design featuring moveable barrier members that allow piglets to safely move around while constraining the sow, with one barrier pivotable and the other adjustable to vary the floor area, and a heating system integrated into the pen floor, enabling safe stockman access and reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sow is confined to a small area to protect piglets from crushing, then piglet safety is improved, but sow welfare and movement freedom deteriorate
Solution Approach 1:
The barrier members are designed to be moveable rather than fixed, allowing the confined area to be dynamically adjusted. The first barrier member can pivot about a vertical axis, and the second barrier member can be repositioned along the framework, enabling the pen configuration to adapt to different sow sizes and stages of lactation while maintaining piglet protection
2Reliability
If the floor area is minimized to constrain the sow, then piglet protection is improved, but animal welfare requirements deteriorate
Solution Approach 1:
The moveable barrier members enable the pen to provide minimum space requirements for sow welfare while maintaining effective confinement for piglet protection. The barriers can be positioned to create adequate space for sow movement and comfort while still preventing her from accessing areas where piglets might be vulnerable
3Adaptability or versatility
If the sow is allowed more freedom of movement to improve welfare, then sow welfare is improved, but the risk of accidentally crushing piglets increases
Solution Approach 1:
The dynamic barrier system allows the pen to provide sufficient space for sow movement and welfare while maintaining clear boundaries that prevent the sow from accessing areas where piglets are most vulnerable. The moveable nature of the barriers allows flexible configuration to balance sow freedom with piglet safety
4Reliability
If barrier members are positioned close together to prevent sow passage, then sow confinement is improved, but piglet movement freedom deteriorates
Solution Approach 1:
The barrier members have different structural characteristics at different heights. The upper portions are positioned close together to prevent sow passage, while the lower portions have gaps that allow piglets to pass freely. This local differentiation of barrier properties enables simultaneous achievement of effective sow confinement and piglet movement freedom
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances piglet survival rates by maintaining a safe environment, allows for increased sow movement as piglets grow, and facilitates safe stockman access without risking injury from the sow, while providing a warm and safe area for piglets using a heatable floor.
Implementation Method 1
certain measures may have to be taken to ensure the welfare of her litter of piglets. Firstly, piglets shortly after birth need to be kept at a temperature close to 30°C, and even in a facility which is provided indoors some means of heating might have to be provided to keep the piglets warm

AI summary
A structure for a farrowing pen having a framework provided with first and second barrier members (36, 40) between which a sow can be confined, wherein at least one of the barrier members is moveable relative to the framework to vary the floor area available to accommodate the sow.
