An attempt at behavioral enrichment for a captive male lowland gorilla

An attempt was made to overcome the lethargic behavior of a singly housed male gorilla. The animal was provided with a plastic ball and burlap bags, and his food was intermixed with hay in order to encourage foraging behavior. Behavioral...

Social enrichment of the environment with infants for singly caged adult rhesus monkeys

Twenty-nine weaned rhesus monkey infants were removed from breeding troops to avoid overcrowding and were placed with unfamiliar singly caged adults without prior familiarization. Adult-infant pairs were compatible in 90% of cases. Compatibility depended neither on the sex, age, or...

Improved installation method for branches that are used as cage enrichment for macaques

We attach the branch in such a way that the animal can both perch on it and freely move below it. ... We are confident that we have found an optimal way to eliminate the need of special cleaning due...

Alternatives to chronic restraint of nonhuman primates

Despite attention to details of conditioning and daily assessments of the animals' health status, chronic chair restraint is accompanied by inherent problems such as skin abrasions, necrosis of the ischial callosities, position-dependent edema, inguinal hernia, rectal prolapse, and laryngeal air...

Urinary gonadotropin and estrogen excretion during the postpartum estrus, conception, and pregnancy in the cotton-top tamarin (Saguinus oedipus oedipus)

The results indicated that enrichment is more determinant than cage size, as more voles developed stereotypies in SB and BB than in SR and BR.
