Effects of Enrichment Presentation and Other Factors on Behavioral Welfare of Pantropical Spotted Dolphin (Stenella attenuata)
Contributor(s): Perez, Barbara C., Mehrkam, Lindsay R., Foltz, Amanda R., Dorey, Nicole R.
Environmental enrichment is a crucial element of promoting welfare for animals in captivity. However, enrichment programs are not always formally evaluated for their efficacy. Furthermore, there is little empirical evidence of enrichment evaluation for species of small cetaceans in zoological...
Effects of Calf Horn as Chews on the Behavior of Laboratory Dogs
Contributor(s): Ketter, Daphne A., Klima, André, Küchenhoff, Helmut, Dobenecker, Britta, Schmidt, Jörg, Erhard, Michael H., Döring, Dorothea
It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of calf hooves as chewing objects. In this report, we describe the...
Effect of Visitor Perspective on Adoption Decisions at One Animal Shelter
Contributor(s): Southland, Anastacia, Dowling-Guyer, Seana, McCobb, Emily
This study investigated the visitor experience at one urban animal shelter. While several previous studies have examined the reasons particular nonhuman animals are chosen by adopters, few have investigated the possible reasons one would visit a shelter and leave without adopting. Over a...
Effect of switch trimming on udder and teat hygiene of dairy cows
Contributor(s): Ingle, Heather D., Rice, Christa A., Black, Randi A., Childers, Sarah Z., Eberhart, Nicole L., Prado, Maria E., Krawczel, Peter D.
The study objective was to determine the effects of trimming the switch of dairy cows on teat-end bacterial counts and udder hygiene scores. Cows (n = 102) were blocked by days in milk, milk production, and parity and then assigned to (a) treatment (trimming of their tail switch using a...
Effect of simple and low-cost enrichment items on behavioral, clinical, and productive variables of caged laying hens
Contributor(s): Frediani, Mayra H., Pizzutto, Cristiane S., Alves, Maíra B. R., Pereira, Ricardo J. G.
Housing layers in battery cages is a practice still used by many countries but it has been criticized because of its influence on behavioral repertoire of birds. We investigated whether simple and affordable enrichment devices alone impact behavior, foot condition and performance of laying hens...

Effect of Cage Type on Fecal Corticosterone Concentration in Buck Rabbits During the Reproductive Cycle
Contributor(s): Cornale, Paolo, Macchi, Elisabetta, Renna, Manuela, Prola, Liviana, Perona, Giovanni, Mimosi, Antonio
Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and...
The Effect of an Irregular Feeding Schedule on Equine Behavior
Contributor(s): Zupan, Manja, Štuhec, Ivan, Jordan, Dušanka
We used eight horses 1 to 12 years old to investigate the influence of irregular feeding times on the behavior. The animals were housed in individual boxes, fed with hay ad libitum and barley-oat mixture at three set times; 05:00 (earlier feeding) on Thursdays, 07:00 (delayed feeding) on...
Effect of Adopters' Lifestyles and Animal-Care Knowledge on Their Expectations Prior to Companion-Animal Guardianship
Contributor(s): O'Connor, Rachel, Coe, Jason B., Niel, Lee, Jones-Bitton, Andria
Human expectations can greatly affect the human–companion animal relationship, sometimes putting nonhuman animals at risk for relinquishment. At 20 animal shelters in Southern Ontario, Canada, potential adopters (N = 234) completed a questionnaire regarding their lifestyle, companion animal-care...
Dutch Consumers’ Willingness to Pay for Broiler Welfare
Contributor(s): Mulder, Machiel, Zomer, Sigourney
This article analyzes Dutch consumers’ willingness to pay (WTP) for the welfare of broiler chickens and the consequences for nonhuman animal welfare policies. Using data from a discrete-choice experiment and a random parameter logit model, this study showed that consumers particularly value...
Does the location of enrichment material affect behavior and dirtiness in growing female pigs?
Contributor(s): Dalmau, Antoni, Areal, Bruno, Machado, Silvana, Pallisera, Joaquim, Velarde, Antonio
The objective of this study was to investigate if female growing pigs spend similar amounts of time exploring a wooden stick as they do exploring enrichment material regardless of its proximity to the feeder. Forty-eight pigs aged 18 to 26 weeks allocated to 16 pens with three pigs per pen were...
Does Enrichment Improve Well Being in Animals under Human Care? A Case Study of Two Harbor Seals (Phoca Vitulina)
Contributor(s): Vaicekauskaite, Ruta, Schneider, Jennifer N., Delfour, Fabienne
Harbor seals in the wild live in a stimulating environment; therefore, nonhuman-animal caretakers have increasingly been using environmental enrichment to improve the well being of seals under human care. The purpose of this study was to evaluate an object-based environmental enrichment program...

Cross-Sectional Study of Characteristics of Owners and Nonowners Surrendering Cats to Four Australian Animal Shelters
Contributor(s): Zito, Sarah, Morton, John, Paterson, Mandy, Vankan, Dianne, Bennett, Pauleen C., Rand, Jacquie, Phillips, Clive J. C.
Unwanted cats surrendered to nonhuman animal shelters are generally categorized as either “owned” or “stray.” This classification is misleading because “stray” cats may include many “semiowned” cats, for which people provide care but who are not perceived as being owned. This differentiation is...
