Effect of cage population density on plasma corticosterone and peripheral lymphocyte populations of laboratory mice

Groups were formed of 2, 4 or 8 animals in cages with a floor areas of 390 sq.cm. The results of this study suggest that population density of 4 mice per cage induced minimal stress compared to that induced by...

The performance of nest building by domestic hens: is it more important than the construction of a nest?

Nest-building behaviour was not [emphasis added] inhibited by the existence of a preformed nest. This finding does not support the hypothesis that animal welfare in intensive housing can be safeguarded merely by providing that environment which would have been created...
