Effects of Rearing on the Behaviour of Zoo-Housed Chimpanzees (Pan troglodytes)
Early-life experiences may considerably affect the behavioural patterns of adult primates. Particularly, atypical rearing practices might lead to abnormal behaviours and social-sexual deficiencies in captive, adult non-human primates. We conducted behavioural observations of mother-reared (n = 5) and hand-reared (n = 6) adult chimpanzees in a social group at Parco Natura Viva, Italy. We used […]
Effects of hand-rearing on the reproductive success of western lowland gorillas in North America

Average daily weight gain in the first 6 months for mother-reared infants (n = 5) was 71.3 g/day; for one partially mother-reared and partially hand-reared infant, 41.5 g/day; and […]
Nursing behavior in dam-reared Russian saiga (Saiga tatarica tatarica) at the San Diego wild animal park
