THE INDIRECT SELECTION RESPONSE TO THE CHARACTERS OF OPEN-FIELD TEST IN MICE AFTER SELECTION FOR BIOMASS PRODUCTION UNDER 3 FEEDING CONDITIONS

The indirect selection response of the characters in the open-field test are described after 13 generations for biomass selection. The selection for LW 42 increased the emotionalism of the animals measured as urination and defecation. On the other side the characters of locomotion decreased through the selection. The exploration behavior measured as standing on at the hind legs against the wall decreased in the selected populations. The open-field behavior was not influenced by the different feeding conditions.
