Q

Reptile & Amphibian cleaning Routine

A
  • Change drinking or bathing water daily
  • Food dishes and water dishes should be cleaned every day
  • Spot cleaning of the substrate should be done regularly – sloughed skin and uneaten food should be removed
  • Faeces and soiled substrate removed (cheaper substrate i.e. newspaper can be removed whenever soiled i.e every 2-3days
  • Complete substrate change depends on type. Astroturf once a week
  • Not all disenfectants safe to use (phenols toxic to rep/amph) 3% bleach solution safe
  • Water used in vivarium should be de-chlorinated

Q

Fish-eating Snake diet

A

Garter snakes are fed on fish and amphibians.

If fed only raw fish they will develop a vitamin B1 (thiamine) deficiency.

To prevent this, the fish must be heated (80°c for 5mins) and cooled.

Diet can also be supplemented with thiamine 35mg/kg of food.

Q

Knowing when to feed snakes

A

Hatchlings will begin to feed after their first shedding of skin (around a week after hatching). They will need to be fed at least once a week.

Feeding routine is based on trial and error as well as watching snakes behaviour

Food for Lizards
Different species may be carnivorous, insectivorous, herbivorous, frugiverous or omnivorous. Some species can change eating habits as they age. Geckos/skinks eat insects/mealworms but these must either be gutloaded or dusted in calcium. Insects which can be provided as food are * Crickets * Fruit flies * Locusts * Mealworms
26
Food for Chelonians
Tortoises are Primarily herbivores. They have no teeth but a hard horny beak which is worn down by eating tough fibrous foods. Should reflect natural diet and be fed ad-lib Plants = Dandelion leaves, Bramble leaves Leafy Greens Veg = Kale, carrot Flowers= Dandelions, courgette flowers
27
Food for Terrapins
Terrapins are omnivores but largely eat fish and aquatic invertebrates. They will only feed in water. A suitable diet of fresh fish i.e. prawns, shrimps , tadpole or tinned catfood/dogfood. Suitable plants are dandelions and watercress.
28
Sexing birds -Budgies
– blue cere and more brightly coloured, female has a beige cere. Surgical sexing involves using an endoscope through ribs into the abdominal airsac where the gonads can be seen. DNA sexing can be done through blood or the pulp of the pulp from a freshly plucked body feather.
29
Breeding birds
Most breed in summer months stimulated by daylight (some stimulated by rainfall and food availability). It is possible to artificially increase day length to 15 hours per day. Boost diet before breeding season & use special breeding cage. Budgies do not line nest, lay eggs in a concave within the nesting box.
30
Suitable nesting materials | for birds
- Spaghnum moss - Twigs/branches - Coconut fibres - Felt liners - Soft dry wood
31
Breeding period for birds
Will normally lay one or more eggs before they start to brood. Brooding usually begins once the second or third egg is laid. The budgies incubation period is 18 days but first egg may have been laid 2 days previous. Incubation temp should be 36.9°C – 37.5°C. Relitave humidity should remain constant to prevent eggs drying out.
32
Budgie incubation period and temperature
The budgies incubation period is 18 days but first egg may have been laid 2 days previous. Incubation temp should be 36.9°C – 37.5°C.
33
Budgie Breeding
Age at first breeding - 9 months eggs laid on alternate days. Can number 3-10 average of 5-6. Incubation 18 days Nest Box. Plywood. 9”x6”x5” lay eggs in concave in nesting box base.
34
Handling birds
- Dim lights - Use a hood for birds of prey - Reduce noise levels - Remove all cage furniture prior to capture
35
Transportation of Birds
- Secure in well ventilated, darkened container - Ventilation holes should be low to avoid dazzling - Disposable cardboard box useful - A new piece of carpet in base of box for ducks - Big enough for bird to stand in but not big enough to flap wings - If using birds own cage, remove all furniture and blanket over the top to darken.

37
Pain and Stress in birds
Mouth breathing Anorexia Ruffled feathers
38
Euthanasia in birds
IV injection of pentobarbitone via ulnar vein OR if difficult to get a vein IM injection of ketamine (40mg/kg) prior to IV injection
39
Ketamin injection for birds
IM injection of ketamine (40mg/kg) prior to IV injection of pentobarbitone
40
Common Nutritional Diseases in birds
Hypovitaminosis A Hypovitaminosis D Iodine deficiency
41
Hypovitaminosis A in birds
Commonly seen in parrots due to all seed diet – pick out sunflower seeds which have low vitamin A. Prevention better than cure. Feed a good variety deep yellow and orange fruit and veg. Sweet potato, carrot, mango, chilli peppers.
42
Hypovitaminosis D in birds
caused by low calcium/high phos diet. Kept in shaded areas. Excess results in calcification of soft tissues. Balanced diet and sunshine to avoid.
43
Iodine Deficiency in birds
Budgies have a high requirement for iodine in diet. Causes enlarged thyroid which presses on the windpipe causing noisy breathing. Give iodine block.
44
Viral Avian Disease
Proventricular Dilation Sydrome- similar to GDV except viral. Affects first part of stomach. Causes damage to crop and proventriculus. Diagnosis is based on clinical signs; weight loss, passing undigested seeds, vomiting, progressive paralysis, no vaccination no cure. Diagnosed post mortem.
45
Proventricular Dilation Sydrome-
Similar to GDV except viral. Affects first part of stomach. Causes damage to crop and proventriculus. Diagnosis is based on clinical signs; weight loss, passing undigested seeds, vomiting, progressive paralysis, no vaccination no cure. Diagnosed post mortem.
46
Bumblefoot
bacterial Caused by standing on same perch for too long, sandpaper and obesity. Causes wounds or injuries to feet, pressure sores and infection. Can be catogerised. (1-3) Prevention better than cure. Use perches various diameters extending bloodflow and pressure. Quality diet. Exercise. Treatment- Ball bandage. Debride, Treat infection. Antibiotic impregnated beads – put in wound. Prognosis poor type 3.
47
Chlamydophylia Psittaci
Zoonotic - Airborne disease. Spread via inhalation of dust off bird faeces, dander and oral & respiratory secretions. Bird can shed disease if immune system down but can carry for months or years without clinical signs. Clinical signs- clear nasal discharge, sneezing, conjunctivitis, green diarrhoea, dyspnoea & feather plucking. Diagnosis – xrays (of lungs and enlarged spleen) and blood test (WBC count) Treatment- tetracyclines & enroflaxin
48
Aspergillosis-
fungal Caused by fungal organism, poor hygiene, stress, vit A deficiency. Can’t be transmitted bird to bird, caused by poor hygiene in cages, mouldy straw and food. Can lead to dyspnoea and death. Can produce aflotoxin which can lead to liver failure. Diagnosis- WBC, xrays, endoscopy Treatment- Surgical debridement, nebulise with amphotericin and itraconizole (oral) oral itroconizole – 3-12 months, 5-10mg/kg b.i.d. IV amphotericin- given over 3-5 days with fluids to prevent renal toxicity 1.5mg/kg
49
aspergillosis treatment
Treatment- Surgical debridement, nebulise with amphotericin oral itroconizole – 3-12 months, 5-10mg/kg b.i.d. IV amphotericin- given over 3-5 days with fluids to prevent renal toxicity 1.5mg/kg
50
Salmonellain birds
bacterial- Zoonotic Spread through water. Carried by rodents, insects and wild birds. Clinical signs- sudden death, enteritis, diarrhoea, wasting, toxaemia, septicaemia, hepatitis Diagnosis- faecal samples. Treatment- difficult
51
Avian Parasites
Scaly beak and tassel foot - mite Red feather mite
52
Scaly beak and tassel foot
- mite affects budgies, cockatiels and canaries. Clinical signs- crusting and enlargement of the cere, beak deformity, thickening of leg skin. Mite eats cell debris. Diagnosis- superficial skin scrape from beak or legs Treatment- invermectin injection
53
