Radiographic examination of keel bone damage in living laying hens of different strains kept in two housing systems

A high prevalence of deviations and fractures of the keel bone is a widespread welfare problem in laying hens. The aim of this study was to experimentally investigate this multifactorial problem throughout the laying period and to compare the prevalence...

Preference index supported by motivation tests in Nile tilapia

The identification of animal preferences is assumed to provide better rearing environments for the animals in question. Preference tests focus on the frequency of approaches or the time an animal spends in proximity to each item of the investigated resource...

Coho salmon (Oncorhynchus kisutch) prefer and are less aggressive in darker environments

Fish are capable of excellent vision and can be profoundly influenced by the visual properties of their environment. Ambient colours have been found to affect growth, survival, aggression and reproduction, but the effect of background darkness (i.e., the darkness vs....

Differences in anticipatory behaviour between rats (Rattus norvegicus) housed in standard versus semi-naturalistic laboratory environments

Laboratory rats are usually kept in relatively small cages, but research has shown that they prefer larger and more complex environments. The physiological, neurological and health effects of standard laboratory housing are well established, but fewer studies have addressed the...

Cage size as a factor in environmental enrichment

Cage size significantly affected 38-day gross body weight, open-field activity and defecation, running-wheel activity, exploration, and water consumption. .. Rearing in large cages, either wire or Plexiglas, appears to reduce emotionality... The results of this experiment indicate that cage size...

A resting platform for dog pens

After converting our dog holding facilities from commercial dog cages to pen type enclosures, it became apparent that suitable resting platforms were needed. Clear acrylic plastic was used to construct the resting platforms.

Deep woodchip litter: Hygiene, feeding, and behavioral enhancement in eight primate species

Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in the deep litter led to...

Captive Primate Working Party Report

It is felt that different cages should be recommended for different species based on their degree of arboreality and the social groupings which were practicable in the laboratory. Weight of animal alone is not an adequate criterion on which to...
