Changing the farrowing system is a far-reaching decision that requires careful consideration. Should I invest in a free-range farrowing pen, or should I switch directly to free-range farrowing? The farrowing pen must be suited to the farm and the people working there. When converting an existing barn, the question arises as to how the pens can best be accommodated. What space is available for the sow and piglets? How much room does the sow have to move about? What is the most suitable arrangement for the farrowing nest, even when the farrowing crate is open, and where is there space to feed the piglets? Furthermore, when deciding on a pen, human factors should also be taken into account. What does the daily work with the pens involve? Is the farrowing crate easy to open and close? What about cleanliness, assistance during birth or occupational safety?2
In new buildings, planning the farrowing pen should begin with the design and layout of the pen areas. This then determines the length and width of the pen – not the other way round.1,3 In older buildings, however, the existing pen geometry forms the basis for the design of the pens. In the case of conversions, the primary consideration must be the dimensions of the substructure (slurry channels).
For exercise pens, the following applies: the pen must be designed in such a way that it functions equally well whether the piglet protection cage is open or closed.
Practical experience
- "Try out a few pen types before choosing a system → alongside the current pen system."
- "Everyone should visit several farms beforehand and then choose a suitable solution; there isn’t one pen that suits all farms and sows."
- "Allow time for selecting the right exercise pen"
- "For new builds, choose the farrowing pen first and then plan the outer structure"
