Q

Describe assessment of wildlife when they are brought into practice.

A
  • Full assessment – where possible
  • Knowledge of natural history – migration, breeding and territory
  • Full clinical examination – under GA if necessary
  • Diagnosis: examination, radiography, blood tests, response to treatment
  • If deemed treatable and releasable – suitable accommodation and suitable food. Treat and asses response to treatment. Reassess at every stage and release or give more time.

Q

Describe the passeriformes/perching birds that come into practice.

A
  • Range from wrens to raves
  • Very prone to septicaemia following puncture wounds such as cat bites
  • Reasons for admission include RTA, window collisions, caught be cat CBCs and orphans
  • Greatly calmed by darkening room
  • Can be stressed to death so be cautious of handling and presence of predators
  • Grounded Hirundinidae and Apodidae – swifts, swallows and matins. Not easy to rear as they are specialised aerial feeders. Often ground, needing test flying. If non-flyers may just need short hospitalisation and retest flying ability daily.

Q

What are some things to remember when handling hedgehogs?

A
  • Do not get ringworm: tedious to get rid of in humans, tends to inoculate under skin from spines, wear thick gloves, wash/scrub hands in pevidine if spined. Scoop up hogs with newspaper.
  • To open up hedgehogs, stroke dorsum backwards from head, bounce gently, gently holding the hind legs, wheelbarrow posture to examine
  • Shallow water
  • General anaesthetic

  • Difficult to orally medicate
  • Easily kept in captivity for prolonged periods
  • Danger that they may be treated where possibly not appropriate, such as burns
23
Q

Distinguish red and grey squirrels in practice.

A

Red – rare, lovable, protected

Grey – common, despised, law actively encourages destruction and forbids release

24
Q

Why are deer admitted to practice?

A
  • Reasons for admission: RTAs, orphans, dog attacks, caught in railings
  • Always radiograph deer that cannot stand on back legs
  • Distressingly common to find pelvic and spinal fractures
25
Q

Why can foxes be admitted to practice?

A

RTA, orphans, snares, old age, shot

26
Q

What makes a release site suitable?

A
  • Ideally all adults go back exactly where found
  • Juveniles need new sites
  • Safe (e.g. roads, hunting, people)
  • Population density suitable
  • Risk of disease transmission
  • Landowner consent
27
Q

What are protected animals in laboratory use?

A
  • All living vertebrates, except man
  • All cephalopods
  • Debate on inclusion of decapods
  • Wild caught primates. Must be bred in a specific research establishment to minimise the impact on welfare.
28
Q

Why do some species get additional protection?

A
  • The act is based around a social contract
  • So public perception of ‘special sense’ dictates which deserve more protection
  • It also dictates what sort of research should be allowed
  • Great apes have highest level of protection
  • Dogs, cats, horses, primates. Companion animals and primates as they are similar to us
29
Q

What is a regulated procedure?

A
  • Any procedure that MAY cause pain, suffering, distress or lasting harm and carried out for a scientific purpose must be documented in a project licence.
  • Each procedure has a prospective severity category, based on potential adverse effects.
  • There are Humane endpoints where the study must be stopped because the benefits of the work no longer outweigh the harms caused to the individual animal.
30
Q

Describe establishment licenses.

A
  • Lists the named persons at the research site
  • What facilities are available and designates room with specific uses (e.g. NSEP, SEP, SF)
  • These must meet the codes of practice: environmental conditions, stocking density and behavioural needs
  • Different to DEFRA
31
Q

Describe personal licenses.

A
  • Grants permission to carry out specific regulated procedures
  • Category of procedure – 5 categories
  • Training record to document competency

  • Must have a PIL to work under a PPL and the ASPA.
  • Could have a personal license to do surgery without having veterinary or medical training.
32
Q

What types of procedures can be done on lab animals?

A
  • Procedures in conscious animals
  • Procedures in briefly anaesthetised animals
  • Surgical procedures or long during anaesthesia (over 15 mins)

37
Q

Describe regulated procedures.

A
  • Any procedure that may cause pain, suffering, distress or lasting harm and carried out for a scientific purpose
  • Each procedure has a prospective severity, based on potential adverse effects
  • Some set limits as to what falls under each category, but plenty of grey areas
38
Q

Describe the mild severity category.

A
  • No significant impairment to well-being/condition
  • Short-term, mild pain, suffering or distress
  • Insertion of a hypodermic needle according to good veterinary practice
  • Procedures that could cause more suffering but effective safeguards can be put in place to treat/end procedure
39
Q

Describe the moderate severity category.

A
  • Likely to experience short-term moderate, or long-term mild, psdlh
  • Procedures likely to moderately impair animal’s well-being
  • Any act of surgery
40
Q

Describe the severe severity category.

A
  • Likely to experience severe or long-lasting psdlh
  • Likely to cause severe impairment of animal’s well-being
41
Q

Describe the non-recovery severity category.

A
  • Animals are anaesthetised at the start of the study and do not regain consciousness at any point throughout the process
  • They are euthanised at the end of the procedure
42
Q

What are the 3 Rs in lab animal use?

A

Replace – has the applicant explored alternative options or can they work to develop non-animal alternatives?

Reduce – appropriate study design to minimise number of animals necessary to attain statistical significance and translatable findings.

Refine
- Using appropriate pain relief
- Ensuring good housing and enrichment
- Ensuring the most refined approach for any procedure

43
Q

Who approves research licenses?

A

Researcher, named veterinary surgeon, named animal care and welfare officer and lay member are the main 4 required.

44
Q

Who are the members of an AWERB review board?

A
  • Researcher
  • Personal License Holder
  • Statistician
  • Named Veterinary Surgeon
  • Surgical Technicians
  • Named Animal Care and Welfare Officer
  • Lay member
45
Q

What is the research scientist tasked with reviewing?

A
  • General scientific background
  • Scientific justification
  • Experimental plans
  • Likelihood of statistical validity
  • Assessing viability of alternatives
46
Q

What is the named veterinary surgeon tasked with reviewing?

  • No unnecessary harm
49
Q

Describe humane euthanasia of lab animals under the ASPA.

A
  • The act specifies how animals must be euthanised
  • This is a “humane” method of euthanasia e.g. Overdose of a general anaesthetic
  • This is known as Schedule 1 euthanasia
  • All personnel should know how to carry out a Sch1 euthanasia of the species they work with
  • This is not a regulated procedure
  • Harder to get CO2 euthanasia wrong but ‘blow to the head’ concussive method is more humane but harder to get right every time.
50
Q

What are the specific guidelines for housing lab animals?

A
  • 5 freedoms met as much as possible
  • Biosecurity and standardisation models
  • Health screening every 3 months
  • Ensuring good enrichment and good health by continually improving practice
51
Q

Describe the biosecurity and standardisation model.

A

Germ Free is the highest level, where animal has no microbial life on its skin or anywhere within its body. Raised in strict isolation with no exposure to any material that has not be sterilised. All water is sterilised, all food and bedding is irradiated. Difficult to maintain so have very strict entry requirements.

Gnotobiotic is the next step down where they are germ free bit introduced to a known specific agent.

SOPF – specific opportunistic pathogen free, meaning any disease causing agents or any agents that may interfere with the research.

SPF

Conventional – intro to a disease that will spread throughout all the animals in eth unit.
