Animal Learning And Training: Implications For Animal Welfare, Sabrina I.C.A. Brando

Assessment of Animal Welfare Collection

KEY POINTS

• A definition of animal welfare is the state of the individual as it attempts to cope with its environment.
• Welfare concerns all of the mechanisms for coping, involving physiology, behavior, feelings, and pathologic responses.
• When training programs are not in place the animal’s welfare could be impaired.
• Some of the behaviors an animal exhibits can be used to gain insight into how the animal feels about the environment, caretakers, and procedures.
• Many contemporary animal trainers and care specialists focus on building relationships using positive reinforcement.

Assessing Animal Welfare: Different Philosophies, Different Scientific Approaches, David Fraser

Assessment of Animal Welfare Collection

Attempts to improve animal welfare have commonly centered around three broad objectives: (1) to ensure good physical health and functioning of animals, (2) to minimize unpleasant ‘‘affective states’’ (pain, fear, etc.) and to allow animals normal pleasures, and (3) to allow animals to develop and live in ways that are natural for the species. Each of these objectives has given rise to scientific approaches for assessing animal welfare. An emphasis on health and functioning has led to assessment methods based on rates of disease, injury, mortality, and reproductive success. An emphasis on affective states has led to assessment methods based …

Identifying And Preventing Pain In Animals, Daniel M. Weary, Lee Niel, Frances C. Flower, David Fraser

Assessment of Animal Welfare Collection

Animals are routinely subjected to painful procedures, such as tail docking for puppies, castration for piglets, dehorning for dairy calves, and surgery for laboratory rats. Disease and injury, such as tumours in mice and sole ulcers on the feet of dairy cows, may also cause pain. In this paper we describe some of the ways in which the pain that animals experience can be recognized and quantified. We also describe ways in which pain can be avoided or reduced, by reconsidering how procedures are performed and whether they are actually required. Ultimately, reducing the pain that animals experience will require …

Assessing Animal Welfare At The Farm And Group Level: The Interplay Of Science And Values, D. Fraser

Assessment of Animal Welfare Collection

In the social debate about animal welfare we can identify three different views about how animals should be raised and how their welfare should be judged: (1) the view that animals should be raised under conditions that promote good biological functioning in the sense of health, growth and reproduction, (2) the view that animals should be raised in ways that minimise suffering and promote contentment, and (3) the view that animals should be allowed to lead relatively natural lives. When attempting to assess animal welfare, different scientists select different criteria, reflecting one or more of these value-dependent views. Even when …

Evaluation Of Animal Welfare By The Self-Expression Of An Anxiety State, M. P. Carey, J. P. Fry

Assessment of Animal Welfare Collection

Although mental well-being has long been accepted as an important aspect of animal welfare, the subjective feelings of farm or laboratory animals are regarded as lying beyond the scope of scientific enquiry. We now report that pharmacological conditioning of pigs with a drug, pentylenetetrazole, known to induce anxiety in man, permits investigation of the presence or absence of this psychological state during exposure to a variety of environmental stimuli encountered during normal husbandry. Such pharmacological conditioning therefore provides a valuable means to assess and improve elements of animal welfare and should be applicable to other species that show operant behaviour.
