Stakeholder attitudes toward farm animal welfare
Journal Articles | Contributor(s): Heleski, C. R., Mertig, A. G., Zanella, A. J.
We developed a survey to measure attitudes toward farm animal welfare, then targeted two US groups considered highly influential in this area: veterinary college faculty members with large animal/food animal emphasis (VCF) and animal science faculty members (ANS). The survey was conducted via...
Genetic analysis of the individual pig behaviour in backtests and human approach tests
Journal Articles | Contributor(s): Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.
The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...

Scientists' assessment of the impact of housing and management on animal welfare
Journal Articles | Contributor(s): Anonymous
A total of 22 scientists contributed to a consensus-oriented conceptual framework for assessment of farm animal welfare, addressing priority issues in cattle, pigs, and chickens. They used the Delphi method, in which participants contributed anonymously through e-mail. The framework puts welfare...
Development of a New Production System for Weaned and Growing Pigs
Journal Articles | Contributor(s): Bjerg, Bjarne, Vestergaard, Kaus S., Pedersen, Jørgen
The design of modem housing systems for farm animals calls for cooperation between scientists within different disciplines. This article describes the design of a new production system for weaned and growing pigs, as well as the analyses and working processes behind its development. The aim of...
A combination of behavioral and physiological indicators for assessing pig welfare on the farm
Journal Articles | Contributor(s): Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.
The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...
Feeder use patterns in group-housed pregnant sows fed with an unprotected electronic sow feeder (Fitmix)
Journal Articles | Contributor(s): Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Baucells, M. D., Gasa, J., Manteca, X.
Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity - housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix...
Can ambient sound reduce distress in piglets during weaning and restraint?
Journal Articles | Contributor(s): Cloutier, S., Weary, D. M., Fraser, D.
This study monitored the vocal responses of piglets, as indicators of well-being, to evaluate the effect of various sounds played during 2 simulations of stressful farm procedures: (a) the 5 min the animals were held as if for castration and (b) the first 20 h after weaning. The sound treatments...
Using data collected for production or economic purposes to research production animal welfare: an epidemiological approach
Journal Articles | 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...
Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene
Journal Articles | Contributor(s): Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.
A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...
Hoop housing for feeder pigs offers a welfare-friendly environment compared to a nonbedded confinement system
Journal Articles | Contributor(s): Lay, D. C., Jr., Haussmann, M. F., Daniels, M. J.
A nonbedded confinement system (NBCS) was compared with hoop structures (Hoop) for housing of feeder pigs. The Hoop is an inexpensive alternative to the total confinement system. Open-ended Quonsets shaped like a half cylinder lying on its flat side, the Hoop use bedding to keep the pigs dry and...
Segregated Early Weaning and Welfare of Piglets

The effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age
Journal Articles | Contributor(s): Rodarte, L. F., Ducoing, A., Galindo, F., Romano, M. C., Valdez, R. A.
Environmental enrichment can be a useful tool to reduce belly nosing behaviors in early weaned piglets. The aim of this study was to assess the effect of environmental enrichment on behavior, salivary cortisol, and productivity of piglets weaned at 14 days of age. The study assigned 112 piglets...
Production costs and animal welfare for four stylized hog production systems
Journal Articles | Contributor(s): Seibert, L., Norwood, F. B.
Nonhuman animal welfare is arguably the most contentious issue facing the hog industry. Animal advocacy groups influence the regulation of hog farms and induce some consumers to demand more humane pork products. Hog producers are understandably reluctant to improve animal well being unless the...
Do domestic pigs in controlled environments contrafreeload?
Journal Articles | Contributor(s): Young, R. J., Lawrence, A. B.
Many experiments report that animals will work (lever press) for food in the presence of freely available identical food. This phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express appetitive behaviour. If this is the case,...
