Body mass and growth rates in captive chimpanzees (Pan troglodytes) cared for in African wildlife sanctuaries, zoological institutions, and research facilities

Captive chimpanzees (Pan troglodytes) mature earlier in body mass and have a greater growth rate compared to wild individuals. However, relatively little is known about how growth parameters compare between chimpanzees living in different captive environments. To investigate, body mass was measured in 298 African sanctuary chimpanzees and was acquired from 1030 zoological and 442 […]

Standardization and validation of a simple, sensitive, second antibody format enzyme immunoassay for growth hormone determination in mithun (Bos frontalis) plasma

Abstract 10.1002/zoo.20069.abs To facilitate research into the action of growth hormone (GH) in mithun (Bos frontalis), we standardized and validated a simple and highly sensitive enzyme immunoassay (EIA) for GH determination in mithun blood plasma on microtiter plates using biotin-streptavidin amplification system and the second antibody coating technique. Biotin was coupled to GH and used […]

Breeding for better welfare: genetic goals for broiler chickens and their parents

Genetics is key to the improvement of welfare in broiler chickens at both juvenile and adult (breeder) stages but progress is hampered currently by the seemingly conflicting demands of welfare, commercial production, food security and calls for increasing intensification to curb climate change. Animal welfare is therefore most likely to be improved on a commercial […]

Body mass dynamics in hand reared clouded leopard (Neofelis nebulosa) cubs from birth to weaning

To study the dynamics of body mass changes in hand reared clouded leopards, we analyzed 3,697 weight data points during the first 3 months of life in 49 cubs from 24 zoo-born litters from 2003 through 2012. All cubs were fed the same formula mixture after a similar weaning protocol. The hand rearing process was […]
