Stakeholder attitudes toward farm animal welfare
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...
A critical review of electrical water-bath stun systems for poultry slaughter and recent developments in alternative technologies
Contributor(s):: Shields, S. J., Raj, A. B. M.
Prior to slaughter, most farmed birds move through a constant-voltage, multiple-bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while...
Animal welfare issues in the poultry industry: is there a lesson to be learned? (Special issue: food animal husbandry and the new millennium)
Contributor(s):: Duncan, I. J. H.
Many of the conditions in which poultry live and the procedures to which they are subjected compromise their welfare. This article describes these welfare problems in the hope that they may serve as warnings to the rest of animal agriculture, which then might take steps to avoid the same...
Changes in substrate access did not affect early feather-pecking behavior in two strains of laying hen chicks
Contributor(s):: Dixon, L. M., Duncan, I. J. H.
Feather pecking, commonly found in flocks of laying hens (Gallus gallus), is detrimental to bird welfare. Thought to cause this problem is the normal housing of layers without a floor substrate. Some evidence suggests that early substrate access decreases later feather pecking. However, there has...
Effect of diet change on the behavior of chicks of an egg-laying strain
Contributor(s):: Dixon, G., Green, L. E., Nicol, C. J.
Injurious pecking has serious welfare consequences in flocks of hens kept for egg laying, especially when loose-housed. Frequent diet change is a significant risk for injurious pecking; how the mechanics of diet change influence pecking behavior is unknown. This study investigated the effect of...
Effects of induced molting on the well-being of egg-laying hens
Contributor(s):: McCowan, B., Schrader, J., DiLorenzo, A. M., Cardona, C., Klingborg, D.
Induced molting in egg-laying hens is an important method for maximizing hen egg production and quality as well as hen health in commercial settings; however, there is growing societal concern over its effects on hen well-being. Using individual hens as their own controls, this research examined...
Humane killing of nonhuman animals for disease control purposes
Contributor(s):: Raj, M.
Reports and guidelines produced by international institutions such as the World Organization for Animal Health (OIE, 2005) describe various methods of killing nonhuman animals. Selection and implementation of a killing method may involve several factors. Preventing or minimizing risk to human...
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...
Quantifying the shelter rabbit population: an analysis of Massachusetts and Rhode Island animal shelters
Contributor(s):: Cook, A. J., McCobb, E.
Scholarly work on the nonhuman animal shelter population has widely focused on cats and dogs. As a result, little is known about the population dynamics of domestic rabbits (Oryctolagus cuniculus) in shelters. The records from 4 companion animal shelters in Massachusetts and Rhode Island were...
Scientists' assessment of the impact of housing and management on animal welfare
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...
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...
Special issue: food animal husbandry and the new millennium. (Special issue: food animal husbandry and the new millennium)
Contributor(s):: Serpell, J. A., Parsons, T. D.
The special issue contains four articles which evaluate animal welfare in livestock production; also, they give a critical appraisal of the food animal industry during this present time. The first two articles deal mainly on the changing attitudes and public perceptions of animal agriculture in...
The European Union ban on conventional cages for laying hens: history and prospects
Contributor(s):: Appleby, M. C.
Since the publication of "Animal Machines" (Harrison, 1964), there has been widespread public pressure in Europe - supported by European institutions - to "ban the battery cage." The European Union (EU) and national governments (particularly in Northern Europe) funded research on noncage systems...
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...
Welfare, health, and hygiene of laying hens housed in furnished cages and in alternative housing systems
Contributor(s):: Rodenburg, T. B., Tuyttens, F. A. M., Sonck, B., Reu, K. de, Herman, L., Zoons, J.
The aim of this review was to compare welfare, health, and hygienic status of laying hens housed in furnished cages and in alternative systems. In alternative systems (floor housing and aviaries), birds have more freedom of movement and a more complex environment than in furnished cages. However,...
