A visual display board used for efficient breeding and utilization of an athymic (nude) mouse colony.

A visual display board was designed to aid in the management of a barrier sustained athymic (nude) mouse colony. The board displayed pertinent information for breeding and weaning, including phenotype and age for each animal in the colony. In addition, the board showed the availability and current status of experimental groups. This system provided an efficient means of organizing production and planning utilization of animals in the colony.
