Importance of Rabbit

  1. Meat: The meat of rabbit is white, fine grained, tender and nutritious. The meat of rabbit is even more nutritious than that of poultry chicken.
  2. Rabbit skin or pelt: This can be used for making jackets, head-gear, carpets or rugs and other decorative households or ornaments.
  3. Manure: It has been discovered that rabbit manure is high in nitrogen and phosphorus and therefore can be used to improve the fertility of the soil.
  4. For research purpose: At the National Veterinary Research Institute (N.V.R.I), Vom, rabbits are kept largely as laboratory animals.

 

Problems Militating Against Rabbit Production in Nigeria

Major problems which militate against commercial production of rabbits in Nigeria include:

  1. Unpredictable breeding behaviour of rabbits.
  2. Incidence of respiratory diseases, e.g ., snuffles and pneumonia.
  3. Inadequate sanitation and proper sanitation programmes.
  4. High nest-box mortality of litters.
  5. Lack of ability to embark on mass production, because most operation in rabbitry cannot be automated.
  6. It is labour-intensive.
  7. Lack of capital also impedes large investment in rabbitry.
  8. Inadequate supply and high cost of concentrate feeds.

 

Housing of Rabbits

  1. Rabbits are usually kept in hutches.
  2. The hutches are arranged in single, double or triple tiers.
  3. The waist – high, single tier hutches are preferable for they save time and labour in feeding and management.
  4. Wooden or metal hutches with Wire-netting surroundings are widely used.
  5. The hutches are placed under a building usually referred to as rabbitry. The rabbitry must be well ventilated.
  6. The floor of the rabbitry should be made with concrete for easy cleaning.
  7. The roof should be made with corrugated iron sheets or asbestos sheets.
  8. The hutches can also be placed in poultry deep litter-house.
  9. The males are kept separate from the female within the rabbitry.
  10. Legs of hutches should be placed in disinfectant bowls to keep off termites and other insects attack.

 

Feeding

  1. Rabbits are simple stomach herbivores, i.e ., they feed mainly on plants.
  2. Rabbits are given concentrates in form of pellets in small quantities.
  3. The pellets given can be supplemented with Aspilia africana, sweet potato leaves, Amarantus, Water leaf, Centrosema spp, Emilia spp, Tridax spp and Calopogonium spp.
  4. Rabbits can be given poultry grower’s mash in the absence of rabbit pellets. This should, however, be sprinkled with water to prevent wastage and nasal irritation.
  5. The protein content of feeds for dry Does and Bucks should be 12-15% while that of pregnant does and nursing does is 16-20%.
  6. The feed should be served in feeding troughs.
  7. Water should be supplied all the time.

 

Hygiene/Health

Common hygiene or sanitary measures to be adopted in rabbitry include:

  1. Clean the floor of the rabbitry daily.
  2. Disinfect the rabbitry at regular intervals to keep it germ-free.
  3. Clean the feed and water troughs to prevent contamination.
  4. Remove dusts and cob-webs from the rabbitry.
  5. Isolate any sick animal for treatment.
  6. Remove and bury dead animal.
  7. Deworm the rabbits at regular intervals.
  8. Treat the rabbits with drugs such as antibiotics and coccidiostats (Prophylactic).
  9. Keep the surrounding of the rabbitry weed-free.
  10. Provide a disinfectant bath or foot dip at the entrance to prevent introduction of germs into the rabbitry by visitors.

 

Diseases of Rabbits

Common diseases of rabbits include:

  • Coccidiosis.
  • Enteritis.
  • Ear canker mange.
  • Helminthiasis.
  • Ringworm.
  • Sore hock.
  • Mixomytosis.
  • Mastitis (nipple inflammation).
  • Pneumonia.
  • Bloat.

 

1) Coccidiosis

Causative agent: Coccidiosis is caused by protozoon.

The symptoms include:

  • passing of soft faeces which may be blood stained.
  • loss of appetite.
  • loss of weight.
  • death in severe cases.

Control measures include:

  • Treatment of sick animals with coccidiostat.
  • Raising rabbits on wire/raised cages.
  • Prophylactic use of coccidiostats in feeds.

 

2) Enteritis

Causative agent: Enteritis is caused by protozoa, feed changes, stress or through poisoning.

Symptoms include:

  • High temperature.
  • Diarrhoea which smells unpleasantly.
  • Loss of appetite.
  • Watery faeces.

Control:

  • Avoid lumping together the young with different litters.
  • Apply appropriate drugs (antibiotic).

  • Adopt good feeding regime/programme.

 

3) Ear Canker

Causative agent: Ear canker is caused by mange mite.

Symptoms include:

Control Measures:

  • Treat affected ear with appropriate drug (liquid parafin on cotton wool);
  • isolate affected animal;
  • invite a veterinary doctor;
  • use of miticides.

 

4) Bloat

Causative agent: This disease is caused by feeding disorder (when animals eat too much green feed too fast) and also when feeding on mouldy feed.

Symptoms include: distended stomach/abdomen and respiratory difficulty.

Control:

  • Feed animals with balanced diet.
  • Do not allow the animals to get too hungry before feeding.

 

5) Mixomitosis

Causative agent: It is caused by virus.

Symptoms include:

  • Runny nose.
  • High fever.

Control measures:

  • Isolate infected ones.

Symptoms include:

  • Poor growth.
  • Anaemia.
  • Diarrhoea.
  • Death in high infestation.
  • Constipation.

Control measures:

  • Deworm regularly.
  • Practise good sanitation.

 

7) Ringworm

Causative agent: Ringworm is caused by fungus.

Symptoms include:

  • Circumscribed lesion on skin.
  • Loss of hair on affected skin.

Control measures

  • Use of fungicide to cure lesions.
  • Isolate affected animals.

 

8) Sore-hock

Causative agent: Sore-hock is caused by pressing the hock against hard structure which leads to injury and infection.

Symptoms include: raising up the hock when in sitting position.

Control measures:

  • Dress wound with disinfectant solution.
  • Cover wound with antibiotics dressing.

 

Finishing of Rabbit to Market Weight

The adult doe does not have any particular heat period. The presence of a buck could stimulate the doe to come on heat. The gestation period of doe is 31 days.

Prior to kindling, nest boxes and bedding materials are provided for the doe in the hutch. The doe can give birth to four to eight litters at a time. The young ones are fed first with colostrum and after two to three days on milk produced by the doe. After about four to eight weeks, the young rabbits (fryers) are weaned and they will start to feed on solid food and green feed as well. Growth is rapid and in the absence of diseases and parasites, coupled with good feeding programmes and management, the rabbit will mature after attaining 4-5kg at four to six months of age.

Rabbit should never be lifted by their ears or legs as that might permanently injure them. Small rabbits or fryers may be lifted and carried comfortably without hurting them by grasping the loin (between the hips and ribs), with the heel of the hand towards the tail of the animal. For heavy rabbits, grasp a fold of skin over the shoulder and lift, holding the rabbit against the body with its head under an arm, the fore-arm being extended along the side of the animal and the head under its rump for support. This prevents struggling and the rabbit may be carried comfortably.
