The most important nutritional troubles of rabbits Flashcards
The 4 main ones
Consequences of fiber def
AV value of feed mixture
Mycotoxicosis
Feed toxicosis
4 main consequences of fiber def
- Fermentation dyspepsia
- Fur chewing- tichobezoar- angora
- Saccharomycosis
- Incr risk of reovirus and tyzzers
Saccharomycosis: what is it caused by and what are the clinical symptoms
Cyniclomyces gluttulatus
Gas prod in the gut
Invaginations
Clinical signs of Reo and tyzzers, diffs of tyzzers
Reo: DX and hydrocephalus
Tyzzers: bact hepatitis (diff is pregnancy toxicosis)
Fiber overfeeding
Caecum obstruction– colon rupture
No fiber def in:
Brachygnathia superior (teeth jutting)
Hairless mutation
AV (alkaline value) of the feed mixture
This is the bicarbonate amount to the hydrochloric acid in mmol/kg
Sets the pH of 1kg of feed to 3
Modification of AV
Done to prevent Dx!!
- 20ml/L of acetic acid is ok
- 2.5ml/L of lactic acid is not ok
- 20ml/L of lactulose is ok- but has different MOA
- 1:20 beatdin
For treating constipation or portal systemic encephalopathy
670 mg/ml of Lactulose
Mycotoxicosis- the 3 main
NOTE: the rabbit is v susceptible because they recycle mycotoxins by caecotrophy
- Aflatoxins
- Fumonisin B1
- T2
Aflatoxins
LIVER!!
B1 and B2
G1 and G2
M1 and M2
Fumonisin
B1 affects the lungs and brain
T2 toxin
FI
Immune
Brain
Feed toxicosis
Iatrogenic dysbact: ampicillin, clindamycin, lincomycin
Coccidiostats- Narasin
Ld50 is 11.7 mg/kg
diffsL Vit E/Se myopathy- incoordination and paralysis
Fermentation dyspepsia
If low fibre and high starch- the fermentation of undigested starch produces alcohol- and this alcohol feeds clostridium piriforme- it produces toxins that travel to:
- The brain: cause suffocation
- Caecal wall: cause diarrhoea
