Modification of aviary design reduces incidence of falls, collisions and keel bone damage in laying hens
Contributor(s):: Stratmann, A., Frohlich, E. K. F., Gebhardt-Henrich, S. G., Harlander-Matauschek, A., Wurbel, H., Toscano, M. J.
Non-cage housing systems for laying hens such as aviaries provide greater freedom to perform species-specific behavior and thus are thought to improve welfare of the birds; however, aviaries are associated with a high prevalence of keel bone damage (fractures and deviations), which is a major...
Object permanence in the dwarf goat ( Capra aegagrus hircus): perseveration errors and the tracking of complex movements of hidden objects
Contributor(s):: Nawroth, C., Borell, E. von, Langbein, J.
Object permanence is the notion that objects continue to exist even when they are out of an observer's sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly...
Consistency of shelter dogs' behavior toward a fake versus real stimulus dog during a behavior evaluation
Contributor(s):: Shabelansky, A., Dowling-Guyer, S., Quist, H., D'Arpino, S. S., McCobb, E.
Behavior evaluations are widely used by animal shelters and other organizations that rehome dogs. The dog-to-dog subtest is a common feature of most canine behavior evaluations. The use of model devices such as a stuffed dog during this subtest could be convenient for shelters and increase...
Environmental complexity and use of space in slow growing free range chickens
Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.
Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...
The day-to-day management of UK leisure horses and the prevalence of owner-reported stable-related and handling behaviour problems
Contributor(s):: Hockenhull, J., Creighton, E.
While concerns regarding the day-to-day management of domestic horses have been raised in relation to behaviour problems and welfare, most published studies have focused on the management of performance horses and less is known about the routine management of leisure horses and the prevalence of...
The epidemiology of dog bite injuries in Switzerland - characteristics of victims, biting dogs and circumstances
Contributor(s):: Horisberger, U., Stark, K. D. C., Rufenacht, J., Pillonel, C., Steiger, A.
Dogs are a potential source of several health hazards for humans. Public attention has recently focussed on dog bites, and different prevention strategies have been suggested. As few data on dog bite epidemiology are available, a prospective study was conducted in family practices (FP) and...
The prevalence and implications of human-animal co-sleeping in an Australian sample
Contributor(s):: Smith, B., Thompson, K., Clarkson, L., Dawson, D.
Sleep research is characterized by an interest in humans, with the realm of animal sleep left largely to ethologists and animal scientists. However, the lives of sleep-study participants and those with sleep problems frequently involve animals. For the majority of the population in developed...
Non-fatal dog bite injuries in the U.S.A., 2005-2009

Prevalence and antimicrogram of Staphylococcus intermedius group isolates from veterinary staff, companion animals, and the environment in veterinary hospitals in Korea

Transmission and epidemiology of zoonotic protozoal diseases of companion animals

A survey of abnormal repetitive behaviors in North American river otters housed in zoos
Contributor(s):: Morabito, P., Bashaw, M. J.
Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic...
An epidemiological approach to welfare research in zoos: the Elephant Welfare Project
Contributor(s):: Carlstead, K., Mench, J. A., Meehan, C., Brown, J. L.
Multi-institutional studies of welfare have proven to be valuable in zoos but are hampered by limited sample sizes and difficulty in evaluating more than just a few welfare indicators. To more clearly understand how interactions of husbandry factors influence the interrelationships among welfare...
Animal welfare - scientific approaches to the issues
Contributor(s):: Millman, S. T.
Nonhuman animal welfare is of significant public interest, globally and within the United States. Value-based judgments are intrinsic to animal welfare assessment, according to the relative weighting of factors associated with animal performance, health, affective states, and natural living. The...
Current attitudes toward, and incidence of, sterilization of cats and dogs by caregivers (owners) in Auckland, New Zealand
Contributor(s):: McKay, S. A., Farnworth, M. J., Waran, N. K.
This study distributed a questionnaire to cat or dog caregivers (owners) throughout Auckland, New Zealand, to investigate the attitudes of human companions toward the sterilization of their cats and dogs and the degree to which this occurs relative to demographic information gathered. A total of...
Influence of stocking density on tonic immobility, lameness, and tibial dyschondroplasia in broilers
Contributor(s):: Sanotra, G. S., Lawson, L. G., Vestergaard, K. S.
This study assessed the effect of stocking density on the development of fear reaction (tonic immobility), lameness (gait), and tibial dyschondroplasia in broiler chicks of mixed sex. During 3 experiments, the study used 49 500 broiler chicks (Ross 208). Of these, 432 focal chicks were randomly...
Risk factors and remediation of self-injurious and self-abuse behavior in rhesus macaques
Contributor(s):: Rommeck, I., Anderson, K., Heagerty, A., Cameron, A., McCowan, B.
Considered signs of decreased welfare - abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory - may put into question the validity and reliability of scientific research using these animals as models. Providing environmental enrichment decreases...
Using data collected for production or economic purposes to research production animal welfare: an epidemiological approach
Contributor(s):: Dewey, C., Haley, C., Widowski, T., Friendship, R., Sunstrum, J., Richardson, K.
Epidemiologists use the analyses of large data sets collected for production or economic purposes to research production nonhuman animal welfare issues in the commercial setting. This approach is particularly useful if the welfare issue is rare or hard to reproduce. However, to ensure the...
Welfare assessments based on lifetime health and production data in Danish dairy cows
Contributor(s):: Houe, H., Sandoe, P., Thomsen, P. T.
The objective of this study was to describe how information about the whole lifetime of the cow can be used when defining nonhuman animal-based criteria of the welfare of animals on the farm. Often measured over a short period, disease occurrence provides information relevant for assessing the...
A descriptive study of 215 dogs diagnosed with separation anxiety
Contributor(s):: Storengen, L. M., Boge, S. C. K., Strom, S. J., Loberg, G., Lingaas, F.
Clinical records of dogs visiting a behavioral clinic were used to study the behavior and background of dogs with separation anxiety (SA). 215 dogs (with SA) were included in the study, representing 22.6% of the patients seen during the 40 months the study covered ( n=952). Male dogs comprised...
Chewable materials before weaning reduce tail biting in growing pigs
Contributor(s):: Telkanranta, H., Swan, K., Hirvonen, H., Valros, A.
Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...
