Practical feeding Flashcards
Feeding rabbits
- crepuscular feeders
- hind gut fermenters (pure vegetarians)
- like to eat at dawn and dusk
Rabbit food
- Hay, grazing, browsing
- green vegetables
- sometimes concentrates (small amount fed at night)
Types of rabbit food
- Extruded pellets - best
- alfalfa mix - can be sugary
- cheap ‘museli’ mixes - high carb, upset gut flora, poor caecal flora, non-caecotrophy, soiled perineum prone to fly strike, dental disease
- ‘breeder’ pellets
- ‘treats’ often lead to obesity
Problems arising from poor diet in rabbits
- incorrect Ca:P (osteodystrophy, dental disease, calciuria)
- low fibre (poor gut motility, poor caecal flora, non-caecotrophy, dental disease)
What should Ca:P be in rabbits
1.5 - 2 : 1
How much concentrates should rabbits be given in food?
Don’t need any but can have up to 2-3% of BW per day
What greens should you give to rabbits?
- not lettuce
- not carrots daily as very sugary
Feeding guinea pigs
- herbivorous
- eat grass
- require daily vit C
- do not rely on in water supplementation only, or just vegetables
Vitamin C for guinea pigs
Require 10-30 mg/kg/24hrs
Disease may be seen within 14 days of starting a deficient diet
Requirement increases x2 or 3 in disease, growth, pregnancy, lactation, stress, etc
Correct feeding of guinea pigs
Grazing and/or hay
Concentrates adequately supplemented with vitamin C
+/- green vegetables
Avoid cheap mixes and very sugary treats
Problems arising from the incorrect feeding of guinea pigs
Lack of fibre
- Barbering
- Loose stools
Incorrect calcium ratios
- Renoliths and sludge
- Dental disease
Malocclusion
- Usually secondary to scurvy
- The lower teeth curve in and trap the tongue on the floor of the mouth
Scurvy (hypovitaminosis C)
- In young animals: joint swelling/pain
- Adults: malocclusion, poor wound healing, immunosuppression
Chinchillas
- Mountain dwelling herbivores from South America
- cannot tolerate more than 3% fat in diet
Correct diet of chinchillas
Hay
Good quality chinchilla pellets
Treats such as hard vegetables and fruit
Problems arising from the incorrect feeding of chinchillas
○ Dental disease
○ Oesteodystrophy
○ Hypocalcaemic fits
○ Greasy fur, scaly skin
○ Fatty liver disease
○ Paraphimosis
Colic/bloat
Degus
- Octodon degus - a Hystricomorph rodent
- True herbivores
- Lives in colonies with burrow systems in south America (rabbit niche)
- Commonly develops diabetes mellitus if fed diet too high in soluble carbohydrates
- Pellets and hay
Rats and mice
Parasites of man
- Eat whatever we try to grow for ourselves, or what we leave behind
- Require/expect plenty of animal protein in their diet
- True omnivores
Hamsters and gerbils - what they eat in the wild
- invertebrates
- fresh vegetation
- dry seeds
Commercial small mammal foods
- Differ greatly in quality, with many being mixes
- There are not some good pelleted foods available, though also some poor ones
- Consider supplementing with seeds, fresh vegetables/fruit, insects, other protein source
Problems of incorrect feeding in rats, mice, hamsters, and gerbils
- Undersize
- Poor skin/hair loss
- Poor immune system and poor general health
- Poor dentition
