Ekesbo, I. 2011. Sheep. In: Farm Animal Behavior: Characteristics for Assessment of Health and Welfare. Fraser, A. F. , Broom, D. M. (ed), 82-92. CABI, Oxfordshire, UK.

Each chapter follows a consistent pattern describing the behavioral characteristics of the species featured. Reference is made to the natural state before domestication, leading us through the various changes to the present, demonstrating along the...

Gaskill, B., Garner, J. P., Pritchett-Corning, K. 2011. Energy reallocation to breeding performance through improved behavioral thermoregulation. American Association for Laboratory Animal Science [AALAS] Meeting Official Progra

Mice are housed at temperatures which increase their basal metabolic rates and impose high energy demands to maintain core temperatures. Thus, energy may be reallocated from other biologic processes to increase heat production. We hypothesized...

Gaskill, B., Winnicker, C. L., Garner, J. P. et al. 2011. The naked truth: Breeding performance in outbred and inbred strains of nude mice with and without nesting material. American Association for

In laboratories, mice are housed at ambient temperatures between 20 to 24 °C, which is below their lower critical temperature of 30 °C, but comfortable for human workers. Thus, mice are thermally stressed, which can...

Giral, M., García-Olmo, D., Kramer, K. 2011. Effects of wire-bottom caging on heart rate, activity and body temperature in telemetry-implanted rats. Laboratory Animals 45(4), 247-253.

Some experimental procedures are associated with placement of animals in wire-bottom cages. The goal of this study was to evaluate stress-related physiological parameters (heart rate [HR], body temperature [BT], locomotor activity [LA], body weight [BW]...

Improving the home cages of laboratory mice by environmental enrichment has been widely used to reduce cage stereotypies and anxiety-related behaviour in behavioural tests. However, enrichment studies differ substantially in type, complexity and variation of...

Neves, S. 2011. Effects of environmental enrichment on the production of C57BL/6 mice kept in different housing systems. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 788 (Abstract #P201).

The goal of this study was to evaluate the effects of environmental enrichment on the performance of C57BL/6 mice kept in conventional animal facilities (open cage; OC) and individually ventilated caging system (IVC). We analyzed...

Oostindjer, M., van den Brand, H., Kemp, B. et al. 2011. Effects of environmental enrichment and loose housing of lactating so

Weaning of piglets in commercial husbandry systems is earlier and more abrupt than would happen under natural conditions, resulting in low feed intakes and health and welfare problems in the immediate postweaning period. Piglets in...

Pasalic, I., Bosnjak, B., Ivetic Tkalcevic, V. et al. 2011. Cage enrichment with paper tissue, but not plastic tunnels, increases variability in mouse model of asthma. Laboratory Animals 45(2), 121-123.

Environmental enrichment, besides having a great impact on animal welfare, can also be a potential variable in experimental research. Thus, we investigated whether enrichment of cages with paper tissues or plastic tunnels affects scientific outcome...

Scales, M., McDonald, K. M. 2011. Factors influencing the preferred nesting location of laboratory mice. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 773 (Abstract #P128).

Understanding the preferred nesting location of laboratory mice within the cage may serve as a useful, objective, behavioral assessment tool. To determine if caging ventilation rates influenced nesting location, we observed nesting site (front, middle...
