Q

Why neuter female rabbits

A
  • Negate pseudo pregnancy
  • Reduce risk of uterine cancer

Q

Why is pseudopregnancy very possible

A

• Caused by infertile mating or presence of a male nearby (sometimes spontaneous ovulation) – may see changes in hormones and false-pregnancy like changes in behaviour
• One false pregnancy, often leads to more
- CL secretes progesterone, mammary glands enlarge, nest building

25
Q

Region most likely to break and why

A

Lumbar - kicking out

26
Q

Rabbit skin is

• which are normal, BUT can be much larger if rabbit is overweight

29
Q

Rabbits and Ca

A
  1. absorb ALL dietary Ca and then excrete via kidney
  2. most mammals absorb enough to maintain serum Ca within range
  3. For rabs this means serum Ca concs much higher than other mammals and fluctuates
  4. Kidneys are unipapilate
30
Q

Urine

Q

What deos urine look like of rabs with high Ca levels.

Excessive prolonged Ca intake can result in what?

A
  1. Thick and creamy

2. Urine stones

32
Q

What diseases are the French, english dwarf adn mini lop prone to

A

• Dwarf and mini Prone to dental disease due to shortened jaw causing maleclusion and tear duct can be more convultued
• Ear problems
2. French and English
• Issues with ears (ear infections and abrasion)
• French boxy head - dental
• English quite prone to problems of heat loss due to hugeee ears

33
Q

Lion head rabbit

A
  1. shortened skull

2. Stressed quite easily so not best with kids

34
Q

Angora

A
  • Wool type coat
  • Bred for fibre
  • Find it difficult to groom
  • Extremely long and therefore easily matted undercoat
  • Often dirty bottom as find it hard to eat caecotrophs
35
Q

Rex

A
  • 2-4 kg

* Short dense fur, areas in contact with ground can be easily abraided

36
Q

Himilayan

A
  • 1-2 kg

* Distinctive markings of while face and collar

37
Q

Giant rabbit breeds, weight and issues

A
  • Continental giants
  • Flemish giant
  • 11kg
  • Prone to artheritis
  • Issues with weight on hocks and foot pads
38
Q

Belgian hare

A
  • 3-4 kg

* Treat like rabbit, not hare

39
Q

New Zealand rabbit

A
  • NZ red
  • NZ white

40
Q

Netherland dwarf

  • Wild so not best for children v quick
  • Boxy head v probe to dental disease
41
Q

What legislation are rabbits under

A 
1. Animal Welfare act 2006
•5 freedoms/needs
2. Codes of practise for keeping rabbits
•	NI, Wales, Scotland, England
3. England - protected under welfare of farmed animals regulation (2007)
42
Q

Routine health checks

A
  1. Myxomatosis YEARLY. Flies can act as vectors so EVEN indoor rabs can get it but more common
  2. RHD - Viral haemorrhagic disease caused by caliciviris: high mortality and sudden haemorrhage through nose.
    - can affect both indoor or outdoor
43
Q

Rabbit behaviour

A
  1. Social and gregarious species
  2. small family groups, don’t like newbies
  3. kept with companion NOT guinea pig as causes respiratory diseases
  4. Hide pain and injuries (wont make nosies) - prey species
  5. territorial so when cleaning try not to disturb scent marking
44
Q

Why shouldn’t you keep rabbits and guinea pigs together?

A
  1. R can bully
    rabbits can give guinea pigs
  2. Bordatella bronciseptica bacteria which rabbits can have asymptomatically but v problematic to GP!
45
Q

NAme of the main respiratory disease for rabbits

A

Pasturella

46
Q

How much mroe Ca will pregnant, feeding young and growing rabs need?

A

calcium 0.6-1% MORE Ca which is required for optimal health

47
Q

Rabbit diet:

A
  1. at least 80% hay or grass AD LIB!
    mixture of timothy, fescue, cocksfoot and meadowgrass ideal
  2. Alfalfa ONLY for growing or pregnant (high protein and Ca, low fibre)
  3. Supplement with edible wild leafy plants, carrots, spinach, rocket etc
  4. fruit ONLY as treat or training aid
  5. Cereal and concentrate mixes are bad
48
Q

Why are cereal and concentrate mixes bad?

A 
o	High protein, high calorie
o	Selective feeding
o	Reduced caecotrophy
o	Boredom  eat high calory, no more eating for rest of day
o	Dental disease
o	Obesity
49
Q

Why are we moving away from museli with rabbits?

A
  1. hihgly selective feeders
  2. will choose grains and pulses over grass pellets
  3. problematic as no good for grinding teeth, high in calories, sometimes Ca balance not right
  4. reduced caecotrophy can result in dirty botty and vit an mineral imbalance
50
Q

How to gain rabs trust:

A
  • Any stress can reduce gut motility significantly
  • Especially problematic in the vets! – cats and dogs about
  • Take time, handle on floor, on a towel
  • Let them come to you/feel “in charge” – sit on the floor, let them see you
  • Do not touch nose, however stroking round cheeks and chin can mimic natural mutual grooming behaviour
  • Don’t pick up if you can avoid it.
  • Tip of nose sensitive
  • Stroke cheeks and chin, natural grooming behaviour
  • Food is good!
51
Q

Handling advice

A

Ideally introduce from young
• Support hind limbs (if kick out can cause serious damage to spine), keep spine straight
• As little as possible!!!
• Never by the ears, avoid scruff
• Never use Tonic immobility in the place of anesthesia or sedation. They are fully aware, just in state where pretending to be dead. increases cortisol, resp and HR

52
Q

Environment and housing

A 
1. difficult to recreate as warrens are extensive
Must have:
-	Sit up with ears erect
-	Stand up
-	Hop
-	Lie down fully stretched
-	Play
-	Eat and drink
-	Maintain hygiene
-	10-20oC - prone to ehat stroke
-	Variety of levels and spaces 
o Chance to dig, stand on top of things, access to outside
-	Scent marking surfaces
-	Access to outside  BIGGER IS BETTER
53
Q

What do dirty environments predispose to

A
  1. Flystrike/myiasis which can quickly escalate to maggots
  2. Pododermatitis - bones in contact with ground and v little protection apart from hair
  3. Respiratory disease - poor ventilation, ammonia can cause pneumonia
