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...
A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...
Aggressive behavior in two different group-housing systems for pregnant sows
Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.
The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...
Artificial weaning of calves: benefits and costs
Contributor(s):: Reinhardt, V.
Evidence indicates that allowing beef calves to stay in the maternal herd beyond the age of natural weaning promotes animal welfare and may enhance the cows' natural reproductive potential.
Hoop housing for feeder pigs offers a welfare-friendly environment compared to a nonbedded confinement system
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...
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...
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...
Livestock vehicle accidents in Spain: causes, consequences, and effects on animal welfare
Contributor(s):: Miranda-de la Lama, G. C., Sepulveda, W. S., Villarroel, M., Maria, G. A.
Livestock vehicle accidents are rare but involve significant economic, human, and nonhuman farm animal losses. This study obtained information on the characteristics of accidents, the animals involved, and injuries to humans from newspaper reports about livestock vehicle accidents in Spain from...
Measuring motivation in swine: the food-metric scale
Contributor(s):: Patterson-Kane, E. G., Kirkden, R. D., Pajor, E. A.
Understanding how nonhuman animals such as swine respond to their environment and understanding how to provide them with a good quality of life involves using a range of experimental approaches. More and more, ethological researchers are turning to operant methods to answer some of these...
Production costs and animal welfare for four stylized hog production systems
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...
Simple cannulation procedure for serial blood sampling through cutaneous ulnar vein in chickens
Contributor(s):: Bayer, D. M., Mohan, K., Jayakumar, K., Manafi, M., Pavithra, B. H.
The objective of the study was to collect repeated, low-stress blood samples from the ulnar vein of chickens required for pharmacokinetic studies or hormonal assays. The study used 5 apparently healthy, unsexed, commercial broiler chickens about 6 weeks old and weighing 1.7-1.9 kg for serial...

Using conjoint analysis to weight broiler welfare variables based on slaughterhouse data
Contributor(s):: Tuunainen, P., Valaja, J., Valkonen, E., Hepola, H.
The Council of the European Union adopted the welfare directive for broiler chickens in 2007 (Commission of the European Communities, 2007). The directive defines minimum demands and objectives for broiler production ranging from stocking density to welfare. This study found that the level of...
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...
