Efficacy of Blunt Force Trauma, a Novel Mechanical Cervical Dislocation Device, and a Non-Penetrating Captive Bolt Device for On-Farm Euthanasia of Pre-Weaned Kits, Growers, and Adult Commercial Meat Rabbits
Contributor(s): Jessica L. Walsh, Aaron Percival, Patricia V. Turner
Developing effective and humane on-farm euthanasia methods is essential for all livestock industries to ensure that animals do not suffer and are killed humanely. Approved methods are lacking for commercial meat rabbits, potentially leading to poor welfare. We assessed several methods of on-farm...
Is a "Good Death" at the Time of Animal Slaughter an Essentially Contested Concept?
Contributor(s): Qurat ulAin, Terry L. Whiting

Assessment of Plumage and Integument Condition in Dual-Purpose Breeds and Conventional Layers
Contributor(s): Mona Franziska Giersberg, Birgit Spindler
The assessment of plumage and integument condition in laying hens provides useful information about the occurrence of feather pecking and cannibalism. Although feather loss and skin injuries can result from mechanical abrasion or clinical diseases, they are valid animal-based indicators for...

Using Free Adoptions to Reduce Crowding and Euthanasia at Cat Shelters: An Australian Case Study
Contributor(s): Heather M. Crawford, Joseph B. Fontaine, Michael C. Calver
Many healthy adult cats are euthanised annually in shelters, and novel approaches are required to reduce euthanasia rates. Waiving adoption fees is one such approach. However, concerns that less responsible owners will be attracted to free events persist among welfare groups. We evaluated...

Contributor(s): Clarissa S. Cardoso, Marina A.G. von Keyserlingk, Marie Jose Hotzel
The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling...
The Mental Homologies of Mammals. Towards an Understanding of Another Mammals World View
Contributor(s): Marthe Kiley-Worthington
Mammals’ mental homologies include that they look after their young, suckle and protect them; they acquire information about the world by learning. They have five types of sensory receptors and a brain to analyze the information and they feel: that is they are sentient. Mental homologies...
Addressing the Challenges of Conducting Observational Studies in Sheep Abattoirs
Contributor(s): Elyssa Payne, Melissa Starling, Paul McGreevy
The competing needs of maintaining productivity within abattoirs, and maintaining high standards of animal welfare, provide fertile grounds for applied research in animal behavior. However, there are challenges involved in capturing useful behavioral data from the supply chain (from paddock to...
Influence of Professional Affiliation on Expert's View on Welfare Measures
Contributor(s): NIna Dam Otten, Tine Rousing, Bjorn Forkam
The present study seeks to investigate the influence of expert affiliation in the weighing procedures within animal welfare assessments. Experts are often gathered with different backgrounds with differing approaches to animal welfare posing a potential pitfall if affiliation groups are not...

An Examination of an Iconic Trap-Neuter-Return Program: The Newburyport, Massachusetts Case Study
Contributor(s): David D. Spehar, Peter J. Wolf
Local communities in the United States are commonly responsible for selecting the most appropriate method of managing free-roaming cats. Lethal management has been widely utilized for generations, but the use of trap–neuter–return (TNR) has grown in recent decades. Despite expanded...

Contributor(s): Ana Lepe, Valerie Kaplan, Alirio Arreaza, Robert Szpanderfer, David Bristol, M. Scott Sinclair
A survey of the United States and Canadian governmental agencies investigated the environmental impact and relative invasiveness of free-roaming domestic non-native carnivores—dogs, cats, and ferrets. Agencies represented wildlife, fish, game, natural or environmental resources, parks and...
Supporting the Development and Adoption of Automatic Lameness Detection Systems in Dairy Cattle: Effect of System Cost and Performance on Potential Market Shares
Contributor(s): Tim Van De Gutcht, Stephanie Van Weyenberg, Annelies Van Nuffel, Ludwig Lauwers, Jurgen Vangeyte, Wouter Saeys
Most automatic lameness detection system prototypes have not yet been commercialized, and are hence not yet adopted in practice. Therefore, the objective of this study was to simulate the effect of detection performance (percentage missed lame cows and percentage false alarms) and system cost on...

Surgical castration of cattle is a common husbandry procedure, and although this procedure is known to cause pain in cattle and other species, in some countries it is often performed without anaesthesia or analgesia. Society is increasingly aware of this animal welfare issue and it is creating...
Brazilian Citizens' Opinions and Attitudes about Farm Animal Production Systems
Contributor(s): Maria C. Yunes, Marina A. G. von Keyserlingk, Maria J. Hotzel

The Road to Hell Is Paved with Good Intentions: Why Harm–Benefit Analysis and Its Emphasis on Practical Benefit Jeopardizes the Credibility of Research
Contributor(s): Herwig Grimm, Matthias Eggel, Anna Deplazes-Zemp, Nikola Biller-Andorno
It is our concern that European Union Directive 2010/63/EU with its current project evaluation of animal research in the form of a harm–benefit analysis may lead to an erosion of the credibility of research. The HBA assesses whether the inflicted harm on animals is outweighed by potential...
