Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs
| Contributor(s):: Serpell, J. A., Duffy, D. L.
Maturational changes in behavior, and the possible influence of the puppy-raising environment on behavioral development, were investigated in a total sample of 978 prospective guide dogs belonging to four different breeds/crosses. All dogs belonged to the same guide dog organization, and had...
The effect of perches and aviary tiers on the mating behaviour of two hybrids of broiler breeders
| Contributor(s):: Gebhardt-Henrich, Sabine G., Jordan, Anja, Toscano, Michael J., Würbel, Hanno
Broiler breeders are kept for the production of fertile eggs. They face serious welfare problems like aggressive behaviour of the males towards females during mating. Furthermore, broiler breeders are usually kept without perches which are a highly valued resource in chickens. The aim of the...
The effect of two different farrowing systems on sow behaviour, and piglet behaviour, mortality and growth
| Contributor(s):: Loftus, Loni, Bell, Grace, Padmore, Emily, Atkinson, Samantha, Henworth, Andrew, Hoyle, Mark
Farrowing crates have traditionally been used to reduce occurrence of piglet mortality as a result of sow crushing. However the utilisation of traditional farrowing crates has been suggested to contribute to negative welfare for both the sow and piglets. This study compared mortality rates,...
Artificial Neural Network (ANN) as a Tool to Reduce Human-Animal Interaction Improves Senegalese Sole Production

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...
Extensive human presence at an early age of ostriches improves the docility of birds at a later stage of life
| Contributor(s):: Bonato, Maud, Malecki, Irek A., Wang, Magretha D., Cloete, Schalk W. P.
While ostriches are relatively wild birds with a short period of domestication, some birds demonstrate a strong interest in humans. Human imprinting of chicks could therefore facilitate the cooperation of birds for assisted reproduction technology purposes, improving the quality of human–bird...
The Human-Animal Relationship in Australian Caged Laying Hens
| Contributor(s):: Lauren E. Edwards, Grahame J. Coleman, Kym L. Butler, Paul H. Hemsworth
Studies on farm animals have shown relationships between stockperson attitudes and behaviour and farm animal fear, stress and productivity. This study investigated how the avoidance behaviour of Australian commercial caged laying hens may be related to stockperson behaviour, albumen...
Market-driven dairying and the politics of value, labor and affect in Gujarat, India

Feeder space affects access to the feeder, aggression, and feed conversion in laying hens in an aviary system
| Contributor(s):: Sirovnik, Janja, Würbel, Hanno, Toscano, Michael J.
In laying hens, minimal requirements for feeder space (cm per bird) are based primarily on data from small groups of hens (n < 10) housed in battery cages. The aim of the present study was to determine the effects of feeder space on agonistic behaviour, access to the feeder, and production in...
The use of a shaded area during farrowing and lactation in sows kept outdoors
| Contributor(s):: Schild, Sarah-Lina A., Rangstrup-Christensen, Lena, Bonde, Marianne, Pedersen, Lene J.
The hut temperature in outdoor pig production during summer can exceed the upper critical temperature of lactating sows. Therefore, sows may experience hyperthermia, a condition which has several adverse consequences for the welfare of both sow and piglets. Thus, the aim of the current study was...
Use of aerial perches and perches on aviary tiers by broiler breeders
| Contributor(s):: Gebhardt-Henrich, Sabine G., Toscano, Michael J., Würbel, Hanno
Perching, especially during the night, is an innate behaviour of chickens and the provision of perches is mandatory for laying hens in multiple countries. We examined whether broiler breeders of the fast (Ross 308) and relatively slow (Sasso) growing hybrids used aerial perches (P) and perches on...
What stockperson behavior during weighing reveals about the relationship between humans and suckling beef cattle: A preliminary study
| Contributor(s):: Destrez, Alexandra, Haslin, Emmanuelle, Boivin, Xavier
The human-animal relationship is a key component of human and farm-animal welfare. Farm surveys, particularly for pig, dairy cattle and veal calf production, which include regular human contact, showed that animals may face aversive handling during daily work routines, which can significantly...
A prospective exploration of farm, farmer, and animal characteristics in human-animal relationships: an epidemiological survey
| Contributor(s):: Roches, A. de B. des, Veissier, I., Boivin, X., Gilot-Fromont, E., Mounier, L.
Human-animal relationships are essential for dairy farming. They affect work comfort and efficiency, as well as milk production. A poor human-animal relationship can result in stress and accidents to both animals and caretakers and needs to be improved. However, many studies have demonstrated...
Human-animal interactions and safety during dairy cattle handling - comparing moving cows to milking and hoof trimming
| Contributor(s):: Lindahl, C., Pinzke, S., Herlin, A., Keeling, L. J.
Cattle handling is a dangerous activity on dairy farms, and cows are a major cause of injuries to livestock handlers. Even if dairy cows are generally tranquil and docile, when situations occur that they perceive or remember as aversive, they may become agitated and hazardous to handle. This...
Unusual animal behavior preceding the 2011 earthquake off the Pacific Coast of Tohoku, Japan: a way to predict the approach of large earthquakes
| Contributor(s):: Yamauchi, H., Uchiyama, H., Ohtani, N., Ohta, M.
Unusual animal behaviors (UABs) have been observed before large earthquakes (EQs), however, their mechanisms are unclear. While information on UABs has been gathered after many EQs, few studies have focused on the ratio of emerged UABs or specific behaviors prior to EQs. On 11 March 2011, an EQ...

Money for nothing: are decoupled agricultural subsidies just?
| Contributor(s):: Pilchman, D.
Every year, the US government pays farmers billions of dollars not to grow anything. Especially within urban constituencies, politically and geographically distant from food production centers, these decoupled agriculture subsidies may seem to be unjust uses for public tax dollars. But can any...
Freedom of cropping and the good life: political philosophy and the conflict between the organic movement and the biotech industry over cross-contamination
| Contributor(s):: Scott, D.
This paper begins by describing recent controversies over cross-contamination of crops in the United States and European Union. The EU and US are both applying the principle of freedom of cropping to resolve these conflicts, which is based on an individualistic philosophy. However, despite the EU...
Reasoning claims for more sustainable food consumption: a capabilities perspective
| Contributor(s):: Voget-Kleschin, L.
This paper examines how employing the capabilities approach in conceptualizing sustainable development allows reasoning and specifying claims for more sustainable lifestyles. In doing so, it focuses on the example of food consumption because it constitutes an '(un)sustainability hotspot' as well...
The rationality of biofuel certification: a critical examination of EU biofuel policy
| Contributor(s):: Pols, A. J. K.
Certification for biofuels has been developed to ensure that biofuel production methods adhere to social and environmental sustainability standards. As such, requiring biofuel production to be certified has become part of EU policy through the 2009 renewable energy directive (RED), that aims to...
