title: Management and breeding of Aotus trivirgatus.
abstract: Attempts to establish successful breeding colonies of Aotus trivirgatus at this and other laboratories have largely been unsuccessful, resulting in only occasional pregnancies and a rare live birth. After the recognition of seven different karyotypes of owl monkeys, animals were paired on this basis and resulted in a marked increase in conceptions. From 1971 to 1975 only 10 pregnancies occurred but during 1975, there were 19 pregnancies. In addition to proper karyotyping, a period of acclimation and conditioning was required. Mean body measurements and weights of infants were established.
