Q

Describe alpacas.

A
  • Male alpacas = macho
  • Female alpacas = hembra
  • Baby alpaca = cria
  • Alpaca being born is called an unpacking or creation, even though a lot of breeders call it a birthing.
  • Pregnancy for 11-12 months. While gestation period may vary between alpacas, the individual will have the same gestation period for each cria.

Q

Describe camelid fibre.

A
  • Not wool or fleece
  • Measured in microns – average diameter of 66% of a sample, which includes 2000 measured fibres. In alpacas, average micron count can range from 15-45 microns. In adult alpacas, a micron count of 25 or less is desirable. Crimp – an organisation or uniform waviness in an individual lock of fibre.
  • Do not bed them on shavings
  • Do not brush them
  • Vicuna is the finest

Q

How are alpacas sheared?

A
  • Alpacas can be sheared in a standing or lying position, lying may be less stressful for the alpaca
  • Alpacas can be stretched out on a sheering table or on a tarpaulin on the floor
  • Wary about neck trauma that could lead to ataxia

Q

What is a safety precaution that must be taken in alpaca housing?

A

Q

Describe how to hold an alpaca.

A
  1. Wrap one arm around its neck and other is placed on the shoulders
  2. Llamas and alpacas generally respond well to suggestion rather than force
  3. Restraint – alpacas can be ‘chunkered’, which involves restraining the animal in sternal position. Snugly tie a rope passing over the back to secure each of the hind fetlocks.

May drop to their knees and try surprise you by springing back up.

Q

What precautions must be taken when putting a headcollar on an alpaca?

A

Obligate nasal breathers, so nose band must be as high as possible , just below the eyes (not into the eyes so corneal ulcers do not form).

Q

What is the exception to the normally docile behaviour of camelids?

A

Berserk male llama syndrome (BMLS):

  • The exception to this generally placid temperament
  • Hand raised male cria, do not have a fear of people so try to attack them
  • Should be castrated by the age of 2 months or at the latest, before weaning

Q

How often must camelids been foot trimmed?

A

Foot trimming may be required every 6 months and you may be asked to do it as a vet although it can be done by owners. Just trim nail only.

Q

What is the problem with overshot lower jaw in camelids?

A
  • Overshot lower jaw occurs most often and in extreme cases teeth can protrude outside the lips
  • This defect can lead to eating difficulties and starvation although most alpacas on good feed seem to manage well
  • Body condition scoring alpacas with this problem is important
17
Q

Describe the camelid digestive tract.

A
  • Has 3 compartments – C1, C2 and C3
  • C1 and C2 are anaerobic fermentation chambers, hosting microbial flora and fauna
  • C1 contractions happen every 4 minutes
  • Efficient urea re-utilisation means bacterial protein is digested
  • Faecal output probably the best indicator of GI tract disorder – faeces should be hard pellets, as they live in arid conditions so have water preservation.
18
Q

Describe camelid nutrition.

A
  • Alpacas and llamas would naturally graze poor quality grass and herbage
  • 5-7 alpacas per acre suitable
  • Alpacas may not graze long grass and so can starve in a field full of the stuff
  • Topping paddocks may help avoid this problem
  • Complete diet with vitamins A, D and E
  • Trace element requirements can be met by supplementing grazing with concentrates
  • Best to feed small pelleted complete diets
19
Q

What would you feed a healthy and a sick alpaca?

A

Healthy alpacas – hay, Readi-Grass, alpaca specific hard feed. Not coarse mix, cattle feed or straw

Sick alpacas – hay, Readi-Grass, alpaca specific hard feed, sugar beet (soaked), haylage, picked grass, Mollichaff

20
Q

Describe rickets in camelids.

A

Rickets/vitamin D deficiency/hyperphosphataemia

  • Camelids, particularly young alpacas, are particularly susceptible
  • Worst in low inter sunlight areas/dark fibre animals
  • Ill-thrift and/or lameness, severe depression due to time of year and weather
  • Hypophosphataemia is present
  • Marked anaemia develops and recovery is uncommon
21
Q

What should the body condition score of different alpacas be?

A
Wether = 2.5-3.5
Non-pregnant mature female = 2.5-3.5
Mature male = 2.5-3.5
Pregnant female = 3-3.5
Working male = 2.5-3.5
Growing/under 15 months = 3-3.5
22
Q

What scale is used to body condition score camelids?

A
1 = emaciated 
1.5 = poor 
2 = thin 
2.5 = borderline 
3 = moderate 
3.5 = high moderate 
4 = excess
4.5 = fat 
5 = grossly obese
23
Q

Describe camelid reproduction.

A
  • Induced ovulators
  • Females ‘kush’ and waits for male to mount. Ogle and strange noises may occur in the hour long process of mating
  • Tie up female to avoid trauma to the penis
  • Test for pregnancy by spitting off, which tells us if corpus luteum is present at 16 and 32 days. Ultrasound scan of abdomen from 60 days
  • Pregnant for roughly 11 months, which varies between alpacas but is consistent within themselves
24
Q

Describe camelid parturition.

A
  • Very hard to predict
  • Udder development doesn’t correlate to parturition date
  • Most give birth during daylight hours and standing up
25
Q

What is agalactia?

A
  • Not uncommon
  • If no colostrum, it is an emergency and requires plasma from the alpaca
  • If there was colostrum, can supplement with goats milk
  • Try massage of udder and oxytocin to aid milk let-down
26
Q

What is checked and what is normal levels for clinical examination of camelids?

A
  • Normal temperature is 37.5-38.9˚C
  • Heart rate = 60-72 bpm
  • C1 turnover is 3-4 per minute, check faecal output
  • Pulse = no readily accessible arteries
  • Check mucous membranes for colour – pale is bad
27
Q

How is a blood sample taken from the jugular vein in camelids?

A

Either low on the neck the thoracic inlet

OR

Near ramus of mandible, right hand side, as haemotoma on left hand side may occlude oesophagus

Be careful of hitting carotid artery

28
Q

How is a blood sample taken from the thoracic inlet in camelids?

A
  • Skin is thinner and easier to restrain
  • Heavily fleeced makes more difficult
  • Greater chance of jugular cannulation
  • Palpate for ventral projection of 6th cervical vertebra, wrap fingers around site and occlude vessel
  • Aim need medial to projection, towards centre of neck
29
Q

How is a blood sample taken from the high neck?

A
  • Juglar more superficial
  • Separated from carotid so less chance of puncturing
  • Skin is thick
  • Hard to visualise so need to ballott
  • Draw line along ventral mandible, with head slightly flexed
  • Occlude vein to confirm site
30
Q

What are the injection sites in alpacas?

A

Subcutaneous: neck

Intramuscular: quadriceps

31
Q

Which disease should all alpacas get vaccinated against?

A

Clostridial diseases, booster at 6 weeks prior to giving birth

32
Q

Describe parasites in camelids.

A

Endoparasites:

  • Camelids are susceptible to a range of parasites that affect sheep and cattle: nematodes, coccidia, liver fluke
  • Usual rues apply as for sheep and cattle
  • Modified stolls FEC recommended as more sensitive, but less than 10 epg

Ectoparasites:

  • Lice: both biting and sucking lice
  • Mites: sarcoptes, psorotes, chorioptes and demodex
