A

Giants

36
Q

What type of tissue is associated with the sacculus rotundus?

A

lymphoid tissue

37
Q

What is the function of the sacculus rotundus?

A

Provides immunity to the rabbit and acts as a valve at the ileo-caecal junction to prevent backflow

38
Q

What is the function of the fusus coli?

A

Pacemaker that activates the movement of the colon and regulates the type of faeces produced

39
Q

What is the fusus coli regulated by?

A

ANS and Aldosterone

40
Q

Where is the vermiform appendix located?

A

Terminal end of the caecum

41
Q

What is the function of the vermiform appendix?

A

secretes bicarbonate to buffer caecal acids

42
Q

What are the 2 types of faeces that are produced by a rabbit?

A

Fecal pellets and Caecotrophs

43
Q

What type of fibres mainly contribute to the prodcution of fecal pellets?

A

long fibres

44
Q

What type of fibres mainly contribute to the production of caecotrophs?

A

short fibres

45
Q

What can cause urinary sediment to be produced in the rabbit?

A

high calcium intake

46
Q

What is the best hay to give to rabbits?

A

Timothy/meadow hay

47
Q

Why should concentrates not be over fed to rabbits?

A

The rabbit does not spend enough time chewing concentrates. This will result in the teeth not being worn down properly which can lead to dental disease.

Because pelleted food only contains short fibres, if it is the main diet it can resulted in reduced gut motility, increased fermentation and can lead to pain.

48
Q

Why should rabbits not be given leafy greens excessively?

A

Some greens such as kale contain high levels of calcium. This can result in the kidney being overloaded with excess calcium which can lead to renal problems.

Too much sediment can also build up in the bladder which could irritate the bladder wall and lead to cystitis.

49
Q

How are rabbits when they are first offered hay or water?

A

3 weeks old

50
Q

When should greens start to gradually be introduced into a rabbits diet?

A

6 weeks

51
Q

What is the requirement space for a rabbit?

A

1500-2200m2

52
Q

True or False?
High temperatures are better for rabbits then low temperatures.

A

FALSE

low temps are better for rabbits then high temps

53
Q

What should the temperature range of a rabbits environment be?

A

Between 15 and 21 oC

54
Q

What is the best combination of rabbits to have living together?

A

Neutered male and a neutered female

55
Q

When do rabbits become sexually mature?

A

4-6 months

56
Q

True/false?
Rabbits have no true oestrous cycle.

A

True

57
Q

What types of ovulators are rabbits?

A

Induced ovulators

58
Q

How many rabbits are born in a litter?

A

4-12 rabbits

59
Q

Give an example of an adaption that rabbits use when in cold conditions.

A

Peripheral vasoconstriciton of the ears and the tail.

(this diverts heat to other areas of the body and reduces vascular supply to the periphery which in turn reduces heat loss.)

60
Q

Give an example of an adaption that rabbits use when in hot conditions.

A

Arteriovenous shunting with counter current heat exchange in ears, tails and feet.

61
Q

What are the main differences between the skeleton of the rabbit and that of the cat?

A
  1. The skeleton of the rabbit is delicate and makes up only 7-8% of the body weight. This is in contrast to the skeleton of the cat, which makes up 12-13% of its body weight.
  2. In rabbits the pubis is not part of the acetabulum unlike in cats.
  3. In the forelimb the radius and ulna are completely fused whereas in the cat they are seperate bones.
  4. In the hindlimb the fibula is short and is half the length of tibia. These are also fused unlike in the cat.
62
Q

What are the 3 best words used to describe rabbit dentition?

A
  1. Hypsodont: High crowned teeth with enamel extending below the gum line
  2. Elodont: Continually growing throughout life
  3. Aradicular: Open rooted, dont develop anatomical roots
63
Q

What gives rabbit/rodent incisors their chisel shape?

A

Enamel on the outer surface is stronger than the dentine inner layer

64
Q

How many cm do rabbit teeth grow in a year?

A

10-12 cm per year

65
Q

What is the main cause of 50% of medical problems seen in rabbits?

A

dental disease

66
Q

True/ False?
Rabbits are unable to vomit

A

True
(due to oesophagus entering the stomach at an oblique angle)

67
Q

How many gyral folds does a rabbits caecum have?

A

3

68
Q

What is the hindgut made up of?

A

Caecum and colon

69
Q

Where is the Fusus coli located?

A

end of the proximal colon

70
Q

When are caecotrophs produced?

A

Every 8 hours after feeding

71
Q

Where are caecotrophs formed?

A

Caecum and proximal colon

72
Q

True or False?
A high protein diet supports consumption of caecotrophs?

A

False

(a low protein diet supports consumption)

73
Q

What impact does calcium from the diet have on on calcium serum and phosphorus concentrations?

A

Increases serum calcium concentrations and decreases phosphorus concentrations

74
Q

True/ False
Gut calcium absorption in the rabbit is dependant on Vit D

A

False

Absorption is not dependant on Vit D

75
Q

What is the calcium phosphorus ratio in rabbits?

A

12:1

(extremely tolerant of high calcium levels)

76
Q

What controls calcium absorption from the gut?

A

Rapid adjustments in PTH

77
Q

Where do rabbits excrete calcium from instead of through bile?

A

Kidneys

78
Q

Where is the larynx positioned in rodents and lagomorphs and what does this mean?

A

High in the oropharynx

Means they are obligate nasal breathers so mouth breathing = poor prognosis

79
Q

What adaptions does the rabbit lung have in order to meet high oxygen demands despite lung size not being proportinally larger to combat this?

A

Low residual lung capacity: Therefore cannot fully exhale all the air from their lungs which helps to maintain high oxygen levels in their lungs.

They also have good chest wall compliance and have a larger volume of alveoli with a smaller diameter creating a larger surface area within a similar volume of lung

80
Q

Why does Pneumonia spread fast in rabbits?

A

Poor lobulation of lungs

81
Q

Why is it important to raise and lower the head every 2 mins during CPR in rabbits?

A

To encourage diaphramatic breathing because rabbits do not use intercostal muscles during respiration as it is mostly diaphragmatic muscle contractions that are used.

82
Q

What lymph nodes are most prone to issues in the rabbits and rodents due to the high occurance of dental disease?

A

Submandibular and cervical

(drain the oral cavity and the top of the neck)

83
Q

What is the name for the normal oral bacteria that is found in rabbits and guineapigs?

A

Step. Zooepidemicus

84
Q

What type of uterus do rabbits and rodents have?

A

Duplex uterus

85
Q

What accessory glands do male rabbits have?

A

Prostate, semical vesicle, bulbourethral

86
Q

What do male rodents and rabbits produce during corpulation to keep sperm within the vagina after mating?

A

gelatinous plug

87
Q

When do testes descend in the male rabbit?
