Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing
Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.
Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...
Stereotypic mice are aggressed by their cage-mates, and tend to be poor demonstrators in social learning tasks
Contributor(s):: Harper, L., Choleris, E., Ervin, K., Fureix, C., Reynolds, K., Walker, M., Mason, G.
Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social...
Dustbathing behavior: do ectoparasites matter?
Contributor(s):: Vezzoli, G., Mullens, B. A., Mench, J. A.
A presumed function of dustbathing behavior is to remove ectoparasites. Providing dustbathing substrates in furnished cages for laying hens might therefore offer an alternative to pesticide use to reduce ectoparasite populations. We investigated the effectiveness of dustbathing substrates for...
An ethological approach to determining housing requirements of gamebirds in raised laying units
Contributor(s):: Matheson, S. M., Donbavand, J., Sandilands, V., Pennycott, T., Turner, S. P.
Each year, the UK rears around 20-30 million pheasants and 3-6 million red-legged partridges for shooting purposes. However, welfare organisations and some members of the gamebird industry itself have raised concerns about the use of raised laying units for breeding gamebirds. Although the...
Stereotypic behaviours in Melopsittacus undulatus: behavioural consequences of social and spatial limitations
Contributor(s):: Polverino, G., Manciocco, A., Vitale, A., Alleva, E.
The demand for parrots for pet and scientific purposes is an increasing phenomenon. Yet, the cognitive complexity of these animals makes it difficult to fully satisfy their eco-ethological needs in captivity, and strategies commonly adopted for their husbandry are often unsuccessful in...
Evidence of competition for nest sites by laying hens in large furnished cages
Contributor(s):: Hunniford, M. E., Torrey, S., Bedecarrats, G., Duncan, I. J. H., Widowski, T. M.
Furnished cages are designed to accommodate behaviour considered important to laying hens, particularly nesting behaviour. Few researchers have studied the degree of competition for nest sites or the extent to which the amount of nest space affects nesting behaviour in large furnished cages. We...
The effects of witnessing managemental procedures during the light versus the dark phase of the light cycle on behaviour, performance and welfare of laboratory rats
Contributor(s):: Abou-Ismail, U. A., Mohamed, R. A., El-Kholya, S. Z.
Research has indicated that witnessing managemental procedures are stressful to laboratory rats. Yet there has been little investigation into whether the time of witnessing these procedures affects behaviour and welfare in these animals. Ninety-six rats, representing two batches, were used in...

Environmental factors that affect the behavior and welfare of domestic cats ( Felis silvestris catus) housed in cages
Contributor(s):: Stella, J., Croney, C., Buffington, T.
Understanding environmental factors that affect the behavior of cats in cages is important if caretakers are to improve the welfare of confined cats. The aim of this study was to examine the effects of the macro (room) and micro (cage) environments on cat behavior and their implications for cat...
Birds are not more human than dogs: evidence from naming.

Abnormal Behavior in Caged Birds Kept as Pets
Contributor(s):: van Hoek, Caroline S., Ten Cate, Carel
There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

Animal welfare issues in the poultry industry: is there a lesson to be learned? (Special issue: food animal husbandry and the new millennium)
Contributor(s):: Duncan, I. J. H.
Many of the conditions in which poultry live and the procedures to which they are subjected compromise their welfare. This article describes these welfare problems in the hope that they may serve as warnings to the rest of animal agriculture, which then might take steps to avoid the same...
Behavioral assessment of intermittent wheel running and individual housing in mice in the laboratory
Contributor(s):: Pham, T. M., Brene, S., Baumans, V.
Physical cage enrichment - exercise devices for rodents in the laboratory - often includes running wheels. This study compared responses of mice in enriched physical and social conditions and in standard social conditions to wheel running, individual housing, and open-field test. The study...
Cage size preference in rats in the laboratory
Contributor(s):: Patterson-Kane, E. G.
The size of an enclosure is an integral part of how well it accommodates a nonhuman animal's welfare; however, most enrichment studies concentrate on modifying the area inside the enclosure rather than enlarging it. It has been suggested that rats have little need for more cage space, but there...
Cage use and feeding height preferences of captive common marmosets ( Callithrix j. jacchus ) in two-tier cages
Contributor(s):: Buchanan-Smith, H. M., Shand, C., Morris, K.
Determining appropriate feeding regimes has important welfare implications for captive primates. This study examined the preference of food bowl heights in 6 pairs of common marmosets (Callithrix jacchus) housed in a 2-tier cage system. Given that marmosets are arboreal and spend most of their...
Effect of breed, cage type, and reproductive phase on fecal corticosterone levels in doe rabbits
Contributor(s):: Prola, L., Cornale, P., Renna, M., Macchi, E., Perona, G., Mimosi, A.
Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of...
Laboratory rodent welfare: thinking outside the cage
Contributor(s):: Balcombe, J.
This commentary presents the case against housing rats and mice in laboratory cages; the commentary bases its case on their sentience, natural history, and the varied detriments of laboratory conditions. The commentary gives 5 arguments to support this position: (a) rats and mice have a high...
Legal loophole for subminimal floor area for caged macaques
Contributor(s):: Reinhardt, V.
Macaques are biologically adapted to an arboreal or semiarboreal lifestyle. They spend much or most of the day and all of the night in elevated locations well off the ground as a safeguard against predators including humans. When they are on the ground during an alarming situation, they...
