Social organization seems to determine the occurrence of male infanticide in equids. No information about social organization of the maneless zebra (Equus burchelli borensis) has been available, but it was presumed the occurrence of infanticide would bethe same in all subspecies of plains zebra (Equus burchelli). It was found that the probability of a foal´s death was affected by the presence of a new male in the herd and by subspecies. All other subspecies showed male infanticide except for the maneless zebra, which suggests a different social system. This would also support the subspecific status of the maneless zebra.
