The Days and Nights of Zoo Elephants: Using Epidemiology to Better Understand Stereotypic Behavior of African Elephants (Loxodonta africana) and Asian Elephants (Elephas maximus) in North American Zoos
out of 5 stars
| Contributor(s):: Brian J. Greco, Cheryl L. Meehan, Jen N. Hogan, Katherine A. Leighty, Jill Mellen, Georgia J. Mason, Joy A. Mench
Stereotypic behavior is an important indicator of compromised welfare. Zoo elephants are documented to perform stereotypic behavior, but the factors that contribute to performance have not been systematically assessed. We collected behavioral data on 89 elephants (47 African [Loxodonta...
Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos
| Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.
Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...
Cognition and learning in horses (Equus caballus): what we know and why we should ask more
| Contributor(s):: Brubaker, L., Udell, M. A. R.
Horses (Equus caballus) have a rich history in their relationship with humans. Across different cultures and eras they have been utilized for work, show, cultural rituals, consumption, therapy, and companionship and continue to serve in many of these roles today. As one of the most commonly...
Does group size have an impact on welfare indicators in fattening pigs?
| Contributor(s):: Meyer-Hamme, S. E. K., Lambertz, C., Gauly, M.
Production systems for fattening pigs have been characterized over the last 2 decades by rising farm sizes coupled with increasing group sizes. These developments resulted in a serious public discussion regarding animal welfare and health in these intensive production systems. Even though large...

Social behavior of domestic dogs and cats as compared to wild canine and feline species : an honors thesis
| Contributor(s):: Anthony W. Rusk
With the help of animal behavioralists, parallels have been drawn between domestic dogs and cats and their wild cousins. In some respects, social behavior in domestic animals has remained similar to characteristics found in wild animals. General observations of social conduct have been examined....

Social networks and welfare in future animal management
| Contributor(s):: Koene, P., Ipema, B.
It may become advantageous to keep human-managed animals in the social network groups to which they have adapted. Data concerning the social networks of farm animal species and their ancestors are scarce but essential to establishing the importance of a natural social network for farmed animal...
Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping
| Contributor(s):: Fu, LingLing, Li, HuiZhi, Liang, TingTing, Zhou, Bo, Chu, QingPo, Schinckel, A. P., Yang, XiaoJing, Zhao, RuQian, Li, PingHua, Huang, RuiHua
In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...

The potential of Social Network Analysis as a tool for the management of zoo animals
| Contributor(s):: Rose, P. E., Croft, D. P.
Social Network Analysis (SNA) enables the fine scale of animal sociality and population structure to be quantified. SNA is widely applied to questions relating to behavioural ecology but has seen little use in the application to zoo animal management, despite its clear potential. Investment in...
GPS technology as a proxy tool for determining relationships in social animals: an example with African elephants
| Contributor(s):: Hacker, C. E., Horback, K. M., Miller, L. J.
The potential application of GPS technology in determining relationships among social animals was addressed in this study of eight African elephants residing at the San Diego Zoo Safari Park in Escondido, CA, USA between 2009 and 2011. GPS coordinates were collected over nine 24 h periods from...
A critically appraised topic (CAT) to compare the effects of single and multi-cat housing on physiological and behavioural measures of stress in domestic cats in confined environments
| Contributor(s):: Lauren R Finka, Sarah LH Ellis, Jenny Stavisky
BackgroundDomestic cats have evolved from solitary, asocial predators and whilst they may display social behaviours, they can still exist as solitary survivors. Over-population and relinquishment of pet cats are ubiquitous problems worldwide, and rehoming centres (also known as rescues/ shelters)...
Dogs for herding and guarding livestock
| Contributor(s):: Coppinger, L., Coppinger, R., Grandin, T.
Dogs that perform best for guarding and herding livestock have different behavioural profiles, as stated by the authors: 'herding dogs are selected to show hunting behaviours, such as eye, stalk, grip or heel. Guarding dogs are selected to show more of the wild ancestor's puppy-like or juvenile...
Is there a bias against stray cats in shelters? People's perception of shelter cats and how it influences adoption time
| Contributor(s):: Dybdall, K., Strasser, R.
The determination of adoptability is a fundamental issue facing shelters wishing to rehome cats. Many shelters in the United States cannot keep a cat indefinitely and increased time in the shelter environment may lead to reduced animal welfare due to chronic stress or euthanasia. In a series of...
A tail of two monkeys: social housing for nonhuman primates in the research laboratory setting
| Contributor(s):: Seelig, D.
Despite great adaptability, most nonhuman primates require regular tactile contact with conspecifics for their psychological well being. By illustrating the inherent value of social contact and by providing clues to the best ways of satisfying this need, behavioral studies are useful in designing...
Admissions of cats to animal welfare shelters in Melbourne, Australia
| Contributor(s):: Marston, L. C., Bennett, P. C.
Although the number of companion animal (pet) cats (Felis catus) in Australia is decreasing, there has not been a corresponding reduction in feline admissions to nonhuman animal welfare shelters. This study tracked 15,206 cat admissions to 1 large Melbourne shelter over a 12-month period. Data...
Impact of zoo visitors on the fecal cortisol levels and behavior of an endangered species: Indian blackbuck ( Antelope cervicapra L.)
| Contributor(s):: Thangavel, Rajagopal, Govindaraju, Archunan, Mahadevan, Sekar
This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density)....
Increasing the frequency of co-mingling piglets during the lactation period alters the development of social behavior before and after weaning
| Contributor(s):: Kanaan, V. T., Lay, D. C., Jr., Richert, B. T., Pajor, E. A.
The purpose of this study was to determine how increasing the frequency of co-mingling affected piglets' behavior development before and after weaning. Co-mingling once (CM1), piglets interacted with 1 unfamiliar litter Days 10-18 after birth; co-mingling twice (CM2), piglets interacted with 1...
Minimal number of conspecifics needed to minimize the stress response of isolated mature ewes
| Contributor(s):: Carbajal, S., Orihuela, A.
The objective of this study was to determine the minimum number of conspecifics that sheep require to minimize the stress associated with isolation from the flock. The study used twelve 3-year-old Suffolk ewes. Every test day, the study randomly selected 1, 2 or 3 ewes to be visually separated...
