CP: 15—-> 23%
CF: 12-15% (2-3% is indigestible to prevent diarrhea)
DE 10-12MJ
Ca: 4-11g/kg
p: 3-8g/Kg

Q

rabbit feed

A

Fibre: hay
Energy: cereal grains
> Not rye: anti-nutritional, high viscosity on gut,
pentosans!!
Others: roots + tubers (dried sugar beet pulp)
Extracted meals: sunflower meals (protein
source)
Additives: coccidiostats, pellet binders (molasses), vit + minerals.

Q

Sample diet

A

Oats (best), barley wheat
Low levels of corn (high in starch and low amylase production)
Alfalfa: 50% of pellet (helps with the indigestible fibre)
Dried beet pulp
coccidostat
pellet binder (Molasses)

Q

Feed intake

A 
Growing 50-150g
Pregnant: 100-200g
Suckling: 300g
Pregnant + lactating: 450g
Non producing or buck: 130-150g
17
Q

Rabbit milk

A

Fat: 10-15%
Protein: 13.5%

18
Q

Fibre

A 
CF: 12-15%, 2/3% indigestible
NDF: cellulose, hemicellulose, lignin
Cellulose: prod. lactic acid, decr. pH, kill pathogen
ADL: absolutely indigestible Lignin: 
            > Stimulates the gut wall
19
Q

Fibre deficiency:

A 
Fermentation dyspepsia
Sacchromycosis over production
Fur chewing (Angora)
Cl. spiroforme over production
Tyzzers disease: bacillus piliformis
20
Q

Fermentation Dyspepsia

A

Undigested starch fermentation in the caecum: alcohol production causing yellow faeces, gas production

21
Q

Fermentation Dyspepsia

A

Undigested starch fermentation in the caecum: alcohol production causing yellow faeces, gas production

22
Q

Cl. spiroforme

A

Over production: change in pH + lactic acid formation- toxic

23
Q

Tyzzers disease

A

Bacillis piliformis

24
Q

Saccharomycosis

A

Over Production: gas production, prolapse and mucosal damage to stomach

25
Q

CF over feeding

A

Obstipation: colon rupture causing faeces to enter abdomen ==> peritonitis

26
Q

Alkaline value of feed

A 
bicarbonate value = to HCl
pH of 1kg of feed = pH3
Modify AV
     > acetic acid
     > lactulose (binds NH3)
27
Q

Rabbit nutritional troubles

A

Fibre def or over feeding
Alkaline value of feed
Mycotoxicosis
Feed poisoning

28
Q

Mycotoxicosis

A 
Aflatoxicosos
Flumanison B1 (lung + brain oedema)
T2 toxin (decrease appetite, ovary development)
29
Q

Feed poisoning

A

Dysbacteriosis: antibiotics
> incr. pH, cause overgrowth of microflora: diarrhea
Coccidostats over dose: in-coordination, HL paralysis
