Positive Animal Welfare ā Scientific Interest
Opportunities for positive affective engagement
āAnimals interacting with their environment in ways that generate positive experiences
Quality of Life
āOverall balance of positive and negative experiences
Positive Emotions
āExamples include pleasure, contentment, curiosity, social bonding
Happiness
āFocus on an animalās well-being and positive affective states

Animal Mental Status ā Feelings & Experiences
Welfare not solely physical
āHealth, stress levels, and fitness alone are not enough to determine good welfare
Subjective experience matters
āWelfare depends on what animals feel
Focus on unpleasant feelings
āParticularly suffering and pain are key concerns in assessing welfare
Key Researchers
āDr. Ian Duncan ā emphasizes feelings over just physical state
āDr. Marian Dawkins ā emphasizes unpleasant subjective experiences

OIE/WOAH Animal Welfare Definition
Definition
āRefers to the state of the animal itself
Integrated components
āPhysical functioning ā health, growth, reproduction
āMental/feelings ā emotions, suffering, pleasure
āBehaviour/naturalness ā ability to express normal behaviour
Positive measurements
āIncludes positive animal-based indicators of welfare
Scientific emphasis
āStresses use of scientific evidence to assess welfare

Capacity for Affective/Positive Emotions in Animals
Anatomical & Physiological Basis
āNeuroscience evidence shows:
āāCognitive aspects of emotions (e.g., recognizing happy/sad faces) require neocortical processing
āāExperiential states of happiness, sadness, and other basic affective states depend on sub-neocortical limbic circuits
Shared with mammals
āThese limbic circuits are common across mammals, supporting the idea that animals can experience emotions

Animal Welfare In Legislation
European Union Milestones
1952 Establishment Of The European Union
āāNo specific animal welfare agreements
1958 Treaty Of Rome
āāEstablished European Community
āāNo agreements on animal welfare
1999 Treaty Of Amsterdam
āāIntroduced Protocol on Protection and Welfare of Animals
āāRecognized animals as sentient beings that can feel, suffer, and experience well-being
2009 Treaty Of Lisbon
āāArticle 13 emphasizes animals as sentient beings
āāRequires full consideration of welfare requirements

Positive Animal Welfare
Definition
āāDefined by Rault et al. 2025
āāAnimals flourish through predominantly positive mental states
āāIncludes development of competence and resilience
āāGoes beyond good physical health and prevention of suffering
Sources Of Positive Mental States
āāRewarding experiences
āāOpportunities for choice and to actively pursue goals
āāAchieve desired outcomes based on species-specific and individual capabilities
Individual Differences
āāInfluenced by genetic, developmental, and experiential factors
āāExamples: pre-natal, early life, and environmental experiences
Assessment
āāMeasured using animal-based indicators
āāEvaluated over different timescales for a lifetime picture

Positive Animal Welfare ā Limitations
Flourishing
āāConcept not clearly defined scientifically
Positive Mental States
āāSubjective, cannot be directly measured
Sentience Dependence
āāUncertain across species
Competence & Resilience
āāMechanisms and indicators still unclear
Rewarding Experiences
āāDifficult to define and validate
Indicators
āāSpecies- and context-specific, limited validation
Overall Definition
āāConceptual, not yet operational, needs future refinement

Positive Animal Welfare ā Benefits
Raising Animal Welfare Bars
āāAnimal welfare is of huge social concern
Changing Human Behaviour
āāPromotes better treatment of animals
Filling Biological Knowledge Gaps
āāImproves understanding of animal needs
Economic Benefits
āāEnrichment-induced disease resistance

Take Home Message ā Animal Welfare
Origins of Animal Welfare Research
āāBegan with identifying problems, negative internal states, and underlying physical functions
āāSolved problems by manipulating function
Shift to Positive States
āāAnimalsā positive psychological / mental states became an accepted focus in research and legislation
Definition of Animal Welfare
āāRefers to the state of the animal itself ā includes positive and negative experiences
Interaction of Elements
āāBiological functioning and affective states interact to determine overall welfare

The Welfare Shift
Five Freedoms
āāFocus on avoiding suffering and negative states
Quality of Life
āāBalance of positive and negative experiences, emphasizes a good life
Five Domains
āāFramework for assessing welfare, includes physical and mental/affective aspects

The Five Domains Model
Purpose
āāProvides a systematic, structured, comprehensive way to assess animal welfare
Focus
āāConsiders both negative and positive affective experiences
Structure
āāDomain 5: Subjective mental experience
āāDomains 1ā4: Physical and behavioural conditions influencing mental states
Updates
āāRevised over 25 years, fully updated in 2020 to include humanāanimal interactions
Alignment
āāSupports the three core welfare concepts: biological functioning, affective state, natural/behavioural expression

Overview Of The 2020 Five Domains
Domain 1 ā Nutrition
āāAssesses water and food problems and opportunities
āāNegative affects: hunger, thirst, malaise of malnutrition
āāPositive affects: drinking pleasures, flavours, textures, satiety
Domain 2 ā Physical Environment
āāIncludes housing, climate, air quality, substrate, noise, light
āāNegative affects: discomfort, breathlessness, thermal stress
āāPositive affects: thermal, tactile, olfactory comfort
Domain 3 ā Health
āāCovers injury, disease, functional impairment
āāNegative affects: pain, nausea, sickness, weakness
āāPositive affects: vitality, fitness, freedom from disease
Domain 4 ā Behavioural Interactions
āāInteractions with environment, other animals, and humans (new in 2020)
āāCaptures agency, choice, goal-directed behaviour
āāNegative affects: frustration, fear, loneliness
āāPositive affects: play, exploration, bonding, foraging, social contact
Domain 5 ā Mental State
āāIntegrates all affects from Domains 1ā4
āāFull mental experience = balance of negative and positive experiences

The Five Domains Unify All Three Major Welfare Viewpoints
1. Biological Functioning
āāRepresented in Domains 1, 2, 3
2. Affective State (Feelings)
āāRepresented in Domain 5
3. Behaviour / Natural Living
āāRepresented in Domain 4

Five Domains Table

Summary ā Animal Welfare Frameworks
Five Freedoms
āāHistorical foundation
āāFocus on avoiding negatives
2020 Five Domains
āāModern scientific model
āāIntegrates biology, feelings, and behaviour
āāAssessment of:
āāā⢠Physical functioning ā Domains 1ā3
āāā⢠Emotional experiences ā Domain 5
āāā⢠Natural/behavioural expression & agency ā Domain 4
āāIncludes human impacts (new 2020 addition)
āāEnables grading of welfare compromise and enhancement
āāSupports contemporary goals: from minimize suffering to enable good lives (e.g., Quality of Life, āA Life Worth Livingā)
