Introduction: Preweaning mortality of piglets remains a welfare as well as an economic concern in commercial swine herds. Post mortem examination can give insight in specific preventive measures.Materials and Methods:A thorough investigation of preweaning piglet mortality was conducted in 14 loose housed Norwegian piglet producing herds. All dead piglets from one batch of sows in each herd, in tot ...

Introduction:The objective of the present work was to collect preliminary production data on a newly-developed farrowing pen for individually loose-housed sows and to use these results to produce a pen for commercial practice which has a high piglet survival rate and improved sow and piglet welfare.Materials and Methods:The “Sow Comfort” farrowing pen” (7.9 m2) comprises two comp ...

Introduction: Piglet mortality, mainly within the first 4 days after farrowing, is still an important welfare issue and an economical challenge. Variation in piglet mortality between herds with similar genetic material and physical environment indicates that the herd`s management is a crucial factor. The objective of this survey was to assess the importance of different management routines around ...

However, during the last decades we have seen a resurrection of scientific interest in the field of mechanisms ...

The average litter size in domestic sows is around 12 to 14 piglets, but litters of above 20 piglets are not uncommon even i ...
