Q

What is dacrocystitis in rabbits?

A

Where reserve crowns impinge on the nasolacrimal duct

25
Q

What can dental disease cause?

A

Digestive disorders
Perianal matting - caecotrophs more eaten
Poor grooming

26
Q

What is the lobulation of rabbit lungs?

A

Both lobulated

No septa separating the lobules so pneumonia not localised

27
Q

What is it called when rabbits eat at dawn and dusk?

A

Crepuscular

28
Q

What is the primary bacteria in the caecum of rabbits?

A

Bacteroides - rather than lactobacillus

29
Q

How many lobes do rabbit livers have?

A

4-6

30
Q

Which liver lobe can be an issue in rabbits?

A

Caudate lobe - on a stalk so can torsion

31
Q

What animal is the rabbit GI tract similar to?

A

Horse - same in terms of midgut fermenter, always needs to be eating as gut stasis can be life threatening

32
Q

Which areas are glandular and non glandular in stomach?

A

Glandular - fundus

Non glandular - cardia

33
Q

What sphincter is well developed in rabbit stomachs and what does this cause?

A

Cardiac sphincter - cant burp or vomit

34
Q

What does the end of the ilium expand into in the rabbit?

A

Sacculus rotundus

35
Q

What tissue is the sacculus rotundus made up of?

A

Lymphoid tissue

36
Q

What does the sacculus rotundus open into?

A

Ampulla caecalis coli

37
Q

What is attached to the caecum?

A

Vermiform appendix

38
Q

What is the caecum divided into?

A

3 parts - by its flextures into gyri

39
Q

What part of the rabbit GI tract has taeniae and houstra adn how many?

A

Proximal colon
First section has 3 taeniae
Second section has 1 taenia

40
Q

What divides the proximal and distal colon?

A

Fusus coli - third part of proximal colon

41
Q

What does the fusus coli do?

A

Regulates the passage of ingesta into the distal colon as a pacemaker

42
Q

What are the three types of colonic motility?

A

Segmental
Haustral
Peristaltic

43
Q

What is the fusus coli made up of?

A

Circular muscle, highly innervated

44
Q

How are the different GI tract contents dealt with by the fusus coli?

A

High fibre eliminated fast

Nutrient rich particles sent back to caecum to become caecotrophs

45
Q

What is caecotrophy necessary for?

A

Production of vitamin B and K

46
Q

What is caecotrophy?

A

Bacterial fermentation used to synthesis nutrients

Avoids the need to store large volumes of food

47
Q

What are caecotrophs made up of?

A

Richly concentrated digestible fraction

48
Q

What do the different contractions do?

A

Segmental and haustral contractions separate the ingesta into solid and liquid mechanically

49
Q

What do the different contractions do?

A

Segmental and haustral contractions separate the ingesta into solid and liquid mechanically

50
Q

What happens in the hard faeces phase?

A

Solid particles pass down lumen

liquid fraction pass to periphery of haustra then returned to caecum by antiperistalsis

51
Q

When does the soft faeces phase occur?

A

When the rabbit is not feeding

52
Q

What happens in the soft faeces phase?

A

Caecum contracts
Digesta passes into distal colon
Increased motility in distal colon, decreased in proximal colon and caecum

53
Q

What happens to caecotrophs after excretion?

A

Eaten directly from anus
Coated in mucus - prevent acid digestion
Fermentation continues in fundus of stomach
Absorption of nutrients in small intestine

54
Q

What kind of kidneys do rabbits have?

A

Unipapillate - fused cortex, smooth

55
Q

What kind of uterus do rabbits have?

A

Duplex - 2 cervices

56
Q

What kind of young do rabbits have?

A

Altricial

57
Q

What kind of oestrous cycle do rabbits have?

A

Induced ovulators

58
Q

How long are rabbits gestation?

A

31-32 days

59
Q

What accessory sex glands do rabbits have?

A

All of them
