Holmes, L. N., Song, G. K., Price, E. O. 1987. Head partitions facilitate feeding by subordinate horses in the presence of dominant pen-mates. Applied Animal Behaviour Science 19, 179-182.

Six pairs of mares, each with established dominant-subordinate relationships, were allowed to compete for feed in a 112-cm trough following 24 h of deprivations. .. Differences in feeding times between dominant and subordinate mares were greatest in the absence of a partition. .. Differences in feeding times with the solid plywood barrier were not significantly different.
