Animals under 3Kg

21
Q

Describe the access to water needed for waterfowl spp

  • Not only for drinking
  • Also to be able to get their head under water at least
  • Pond (s) – natural or artificial
  • Easy to clean and move
22
Q

Name some geese breeds

Greylag
Toulouse

23
Q

Where needs to be clinically examined in waterfowl spp?

A
  • Temperature
  • Mouth
  • Oropharynx
  • External parasites - Skin, feathers or scales
  • Vent
  • Abdomen
  • Feathers
24
Q

Medial metatarsal vein

25
Q

List some neonatal problems of water fowl spp

A
  • Starving
  • Yolk-sac infection
  • Yolk-sac retention/rupture
  • Chilling
  • Leg and wing deformities
  • Infections e.g. E.coli, Aspergillus
26
Q

What is angel wing?

A

Deformity
- Excessive protein intake during rearing can cause urates to be deposited in soft joints –the carpal area seems to be the last to ossify
- The primary feathers are the last to be produced and at peak primary feather growth the carpal joint deforms with the weight of the blood quills making the primaries eventually point outwards

27

Lameness
Slow growth
Twisted bones

Check diet formulation/management and supplement vitamin D
