• Male ICR-strain laboratory mice (Mus domesticus) which had been reared with a castrated male from 35 to 105 days of age were paired with male mice which had been reared with an intact male from 35 to 105 days of age. Males reared with a casteated male dominated males reared with an intact male, and the former behaved more aggressively towards castrated males than the latter. Males reared with a castrated male until 70 days of age and then reared with an intact male were paired with males which had been reared in the reverse order. The former dominated the latter. The result suggests that cage-mates under 70 days of age are important to determine social dominance. Aggressiveness of males reared with a castrated male in cages which were devided into two compartments by a wire gauze wall was investigated. Males which grew up in a cage where the other compartment was kept empty dominated males which grew up with another pair over the wall. The result suggests that intact males affect cage-mates without physical contact.
