I.N.R.A., Laboratoire de Physiologie et la Reproduction, 73380 Nouzilly, France.


An evaluation of social experience in the establishment of dominance-submission relationships was attempted using 20 animals in various constellations of 4.

The establishment of rank-order in 5 groups of inexperienced heifers upon their first contact with strangers was compared with that in 20 groups consisting of the same animals in different arrangements upon their second to their fifth encounter with strangers.

With experience, the various types of agonistic interactions were differently utilized, contact-forming and fighting time were reduced, the social order was more rapidly and firmly established, and fighting often dispensed with.
