Includes maternal care and lactation.
Several structural enrichment enhancers are described. When a barrel with an opening in the front was hung from the roof of the siamang enclosure, our then solitary male, Mitch, spent much of his time looking...
Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches...
The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...
A survey of selected enrichment programs for group-housed marmosets. Older individuals ... appear to habituate themselves less to the presence of visitors, and get very agitated when approached. ... High perches should be provided to...
It is generally thought that early forced-weaning of infants would reduce the time from parturition to the first fertile postpartum estrus thus maximizing reproductive efficiency. ... From a survey of 23 animal records we determined...
Evidence indicates that allowing beef calves to stay in the maternal herd beyond the age of natural weaning promotes animal welfare and may enhance the cows' natural reproductive potential.
The perceived benefits of permanent, pre-weaning mother-infant separation are not supported by scientific findings. ... As long as there is an excessive number of monkeys and insufficient cage space, there is no ethically legitimate reason...
Successful housing requires knowledge of ferret behaviors including social behavior, eating habits, a general inquisitive nature, and a species-typical need to burrow and hide. Regular handling is necessary to maintain well-being. A ferret health care...
In previous studies of environmental enrichment of mice it has been determined that certain types of mice are affected by manipulation of their living environment. Some have effects on cognitive memory and some affect the...
Forming successful groups of rhesus macaques (Macaca mulatta) can be challenging. Males in particular do not always get along, and some need to be permanently removed due to fighting and trauma. Early rearing condition may...
