title: Hand-rearing baboons for laboratory investigations.
abstract: To conduct laboratory studies in unsedated animals that were similar anatomically and physiologically to man, five full term baboons (four Papio cynocephalus anubis, one Papio cynocephalus cynocephalus) were hand-reared. These infants were used as unsedated animal models in short-term lung clearance studies conducted from birth to 2 years of age. The hand-rearing techniques described here encouraged the formation of an infant-human rearer bond that permitted us to control the level of expressed aggressive behavior as the infant matured. These techniques resulted in baboons which displayed subordinate behavior, showed positive reception to human contact (without evidence of negative stereotypic behavioral anomalies) and remained cooperative subjects for our investigations of short-term pulmonary clearance. The baboons generally were above average in weight in comparison to conspecifically-reared baboons of similar age, sex and species. Representative lung retention curves presented on one baboon demonstrate the feasibility of lung clearance studies in these hand-reared animals. Due to its suitability for unsedated studies, this baboon model may be considered for other types of laboratory investigations.
