Research in cattle, pig and poultry farms emphasizes the importance of the stockperson’s behaviour for the animals’ level of fear or confidence. The stockperson’s interaction with animals has either stress or stress-reducing effects, and in turn affects animal production, health and well-being of the animal. It can also influence the ease of handling. Attitudes and personality of the stockperson differ greatly. Stockperson attitudes influence not only theirinteraction with animals, but also decisions in regard to housing and management. A good human-animal relationship is associated with improved housing and management that proves beneficial for animal welfare. In sum the relationship between the stockperson and his or her animals affects the animals both directly via interactions and indirectly via decision making. New knowledge and experiences can change attitudes. Training programs can thus improve the human-animal relationship and ultimately improve animal welfare.Research in cattle, pig and poultry farms emphasizes the importance of the stockperson’s behaviour for the animals’ level of fear or confidence.
