| Abstract: | Background The husbandry systems for laying hens were changed in Sweden during the years 2001 – 2004, and an increase in the number of
submissions for necropsy from laying hen farms was noted. Hence, this study was initiated to compare causes of mortality in
different housing systems for commercial laying hens during this change. |
