Indicators of Animal Welfare, Exams, Audits Flashcards
Animal Welfare Measurement
Must be based on indicators that can be quantified and that provide information on animal well-being
Eg. Body weight, temperature, leg kicks… vs comfort, pain, happiness
2 types of indicators of animal welfare
Animal-based
Resource-based
Animal-based animal welfare
- changes in behaviour, body condition, overall aspect, clinical signs, human-animal relationship, cleanliness
- harder to measure as it is more time consuming
- includes performance, morbidity and mortality rates, thermal comfort, blood titers, behaviour, handling response, brain function, hormonal activity
Resource-based animal welfare
- space provided, ambient temperature, diet, management (record keeping)
- legislation and assessment uses and focuses on this basis
- quick, objective, no specific formation required
Con to resource-based animal welfare
Not always directly correlated with animal welfare
- Individual variability (temperament, dominance status, size, physiological state) and interaction between multiple indicators (optimal temperature depends on space allowance, type of flooring, humidity, cleanliness)
Characteristics of good indicators of animal welfare
- reliable: inter- and intra-observer variability should be low, and constant throughout different populations (parameters should be similar, variation should be low)
- practical: a function of time and money
- scientifically sound: be aware of the limitations that an indicator could have. Indicators will often be specific to the species and to the problem in question
Distance Exam
Assessment of the patients environment and the possible relationship of that environment to the patient’s problems.
Should observe attention level when animal is undisturbed, and the animal performing normal behaviour
Cattle Response to approach
- The response elicited when approaching a cow
- Flight distance and withdrawal movements
Individual things to look for
Head bearing, ear position, facial expression (eye white, dropped eyelids, dull eyes, nostril cleanliness, chewing/grinding teeth), vocalizing, piloerection, back position, bloated rumen, weight shifting, shivering, tenesmus, tail flicks, lameness
Lameness
Abnormality of movement evident when animal in motion
Locomotion score: 0 when walking normal.
Abnormal walking= back arch, walking with a limp, head bob up or down
Indicators of lameness in moving animals
reluctance to bear weight, uneven temporal rhythm between hoof beats, weight not borne for equal time on each foot
indicators of lameness in standing animals
resting a foot (bearing non-weight or less weight on foot), frequent weight shifting between feet, standing on edge of a step
Clinical signs of bovine respiratory disease
- Coughing
- Nasal or ocular discharge
- Resp issues
- Laboured breathing
- Supported by muscles of abdomen
- Sound
- Increased, shallow breathing
- Varying degrees of depression
- No appetite
Cleanliness
Presence of liquid dirt or plaques, signs of diarrhea = poor cleanliness
Hairless patch vs lesions/swelling
Hairless
- Area with hair loss
- Skin not damaged
- Extensive thickening of the coat due to parasites
- Possible hyperkeratosis
Lesions/swelling
- Damaged skin either in form of a scab or a wound
- Dermatitis due to ectoparasites
- Ear lesions due to torn off ear tags
