Piglet mortality in Swedish pig herds is too high and if the sow should be completely loose or fixed a short time in connection with farrowing, is an important issue. However, to perform internationally publishable studies of piglet mortality, parallel studies in the same herd, are required.


These unique conditions are found in the rebuilt stables at Önnestad Gymnasium, owned by Hushållningssällskapet in Kristianstad. Here, piglet mortality in two pen types (A; farrowing pen for a loose sow and B; farrowing pen for a temporary fixed sow), in combination with optimal management routines, will be compared. Detailed and supplemented description of methodology is presented in Appendix 1. The purpose is to answer the question whether there is a difference in the total piglet mortality (stillbirths and deaths during the lactation period) between the two pen types. Overall objective is to reduce piglet mortality in Swedish pig production.
