Assessing the value of television as environmental enrichment for individually housed rhesus monkeys: A behavioral economic approach

The goal of this study was to evaluate television as a source of environmental enrichment for individually housed rhesus monkeys (Macaca mulatta) by using the concepts of behavioral economics. Phase I entailed the use of operant conditioning to assess the...

The problem with nestlets and Athymic Nudes

A colony of Hsd:Athymic Nude-nu mice was found to have an increased prevalence of conjunctivitis. .. It was theorized, because Athymic Nude mice lack the normal fur, i.e., guard hairs, and eye lashes, the fibers from nestlets can easily become...

Use of temporary and semitemporary enrichment objects by five chimpanzees

The results of this study emphasize the importance of temporary object rotation and presentation of both temporary [paper, magazines, raisin boards, cardboard boxes, etc.] and semitemporary [nets, climbing structures, straw, grass, etc.] objects to captive chimpanzee environments. This work has...

Effects of physical enrichment on agonistic and exploratory behaviours of several groups of lesser mouse lemurs, Microcebus murinus, in captivity

The aim of this study was to evaluate environmental enrichments [branches, foraging devices] intended to decrease aggression [of this semi-solitary nocturnal prosimian] and to increase the diversity of their behavioural repertoire.

Puzzle feeders and gum feeders as environmental enrichment for common marmosets

The results of this study indicate that gum feeders and Puzzle-Feeders' loaded with waxmoth larvae are useful for reducing the rates of pacing and inactivity in single-housed and in pair-housed marmosets.

Effective strategy for evaluating tactile enrichment devices for singly caged macaques

We present a simple, yet effective, tactile device scoring system used with singly caged macaques indicating that creating and documenting enrichment ideas can be accomplished without a large personnel and budgetary commitment.Abstract of this work has been published in: Contemporary...

Responses of adult laying hens to abstract video images presented repeatedly outside the home cage

The present findings clearly demonstrate that abstract video images, presented in front of the home cage for 10 min on consecutive days, reliably attracted and sustained the interest of individually housed laying hens for as long as 8 days.
