Examining domestication effects on behavior in pigs and hens using The Observer

Gustafsson M.

Domestication is the process by which animals that we keep in our farms today have been genetically changed from their ancestors.
In this study the hypothesis that wild animals use a more costly behavioral strategy in comparison to domesticated animals is tested with The Observer XT 12. The premise of this hypothesis is that during domestication, humans provided animals with food and protection, which may have resulted in the gradual loss of behaviours needed in the wild situation.
