1. Developing rats were growth-retarded during gestation and the suckling period by underfeeding their mothers from mating. After weaning, all animals were fed ad lib.

2. At 18 weeks each male was paired with another male for 10 min on 4 consecutive days. Tests 1 and 2 were with males of like-treatment group and tests 3 and 4 with males of unlike-treatment group.

3. Pairs of previously undernourished rats boxed and fought more often than pairs of controls. In the mixed pairings of tests 3 and 4 the previously underfed animals initiated contact more frequently than did their control partners.

4. Evidently there is a lasting effect of early nutritional deprivation on inter-male social behaviour, especially when both of the animals interacting are of the previously undernourished type.
