| Abstract: | Background According to the Norwegian animal welfare regulations, it has been forbidden to build new tie-stall barns since the end of
2004. Previous studies have shown that cow performance and health differ between housing systems. The interaction between
housing system and herd size with respect to performance and disease incidence has not been evaluated. |
