Establishment of small breeding colony of rhesus monkeys.

ABSTRACT

A breeding colony of 22 female and 4 male rhesus monkeys (Macaca mulatta) was established in a controlled-environment building with an outdoor run. The animals were quarantined for 2 years prior to their release into the unit. The housing, release and management of the colony are described. During the first year 19 young were born of which 17 have survived to 6 months of age. The cost of production and maintenance of the colony when compared with the cost of importing rhesus monkeys would appear to be acceptable.
