Rabbit farm Query from: Dr Karikkathil Smita Sivadasan of Ernakulam in Kerala


Rabbit farm Query from:
Dr Karikkathil Smita Sivadasan
SMS (Animal Husbandry)
Krishi Vigyan kendra (of CMFRI), ICAR
Kasturba Nagar, Kadavantra P O,
Ernakulam Dist- 682 020
Kerala State

Case report from a very small unit of 6 rabbits here at Ernakulam.

The details of the case reported are as below

The unit is being maintained in an unhygienic way. The shed is simply a tarpaulin sheet tied on side of their house with no proper ventilation. It is surely getting very damp due to the continuous rains here. They have reported two deaths last week showing sneezing, loss of appetite, and watery to yellowish discharge from the nostrils and labored breathing in later stages. Since I was not in station, suspecting pasteurellosis, i had advised enrofloxacin orally but they had given Amoxycillin orally and the rabbit died next day. The second death was not reported. Now one of their rabbit is reported to be lethargic, off feed and lying most of the time on one side of the cage.
Remarks: Hygiene in rabbitry is the foremost important. Whether they have cages or not? Tell them there is no scope for saving those rabbits

My query regarding the above case is

  1. Whether it is safe to give Amoxycillin orally in rabbits? I have read that it may cause slow death in some rabbits due to digestive disturbance.

Ans: Under the scenario mentioned above, not advisable to give oral medications at all. Yes, it is not safe to give Amoxycillin orally to rabbits. Instead try to give long acting penicillin injections intra muscularly using sterile needle.

  1. The feed box is also very much damp and the unused feed is lying in it since they have brought the unit. They have not cleaned till this day. Can fungal toxins cause such symptoms?

Ans: Yes, fungal toxins sure to form. Daily cleaning of feeders is most important. Why they rear
rabbits like that? (unhygienic and unethical way)

  1. The present rabbit is not showing any head tilt or discharge from its nostrils. They have not fed grass for the past 4-5 days due to continuous rains here. As such it is not showing any pain on palpation. They have not noted whether faeces are being voided or not. Can less fibre in diet cause such symptoms? They have reported to have given Amoxycillin yesterday and today. I have advised enrofloxacin orally along with liver tonics.

           Ans: Problem is pneumonia. Under this severe conditions, No oral medication please. Prevention
           is better than cure. Try giving Hostacycline powder through feed/water for 3 days to the         
           remaining rabbits.

Question 1.    Good rabbit farmers, their addresses and management practices that make their enterprise unique with some exclusive photographs of such enterprises.
Ans = Mr.Arul kumar Mob: 09841616111 having a very good rabbit farm near Udumalpet in Thiruppur District of TN. At present the rabbit strength is around 2000. Having 8000 sq. ft building with modern facilities. About 2 hours journey from Coimbatore towards Palani.
Question 2.      Other than Chinchilla and White Giant what are the new lines that might be promising as a meat purpose.
Ans = Dutch, Black Brown, Grey Giant, Flemish Giant, New Zealand white and Californian rabbits.
Question 3.      Automation of rabbit farm to reduce drudgery, nipple waterer, rabbit feeder and waterer, other fumigation measures, chemicals that could be used to fumigate, those to be used as water sanitizers
Ans =One can visit the rabbit farm of Mr.Arul kumar Mob: 09841616111 to get first hand information on the above aspects. Flame gun has to be used for cleaning the cages and sheds. No chemicals are to be used. Potable water is sufficient, hence no need of sanitizers.
Question 4.     Diseases, especially coccidiosis, pastuerellosis, cannibalism, worms, fungal skin diseases, mange, allergy, rhinitis, pneumonia with their recent treatments and post mortem findings etc with photographs
Ans = Prevention is better than cure. Good management will avoid diseases. However Disease wise treatments;
Coccidiosis = use Supercox or Rancox through water @ 2gm/lit of drinking water for 5 days before weaning the youngones from mothers. Weaning at 6 weeks of age
Pasturellosis = Use enrofloxacin antibiotic liquid @ 10 ml/lit of drinking water for 3 days
Cannibalism = it is a managemental problem, provide adequate protein in the feed
Worms = not a problem in caged rabbits, hence no deworming needed
Mange = Apply ascabiol lotion; sterilize the cages and sheds by using flame gun. If not subsides with 14 days, give HITEK oral liquid 0.5 to 1.0 ml. In severe cases try Injection Ivermectin 0.1 ml s/c route
Pneumonia = Use injection Benzathine penicillin 0.5 ml i/m  route. Provide good ventilation and avoid over crowding.
 Question 5.      Feeding practices that could reduce cost of concentrates, alternate feeding approaches to reduce cost. New concentrate formulations for farmers to reduce feed cost
Ans = Palatable, non-poisonous tree leaves and vegetable wastes can be effectively used for feeding. Kitchen waste can be used. Cheaper source of grains, oil cakes/ protein sources and brans can used at equal portions with 1% each of calcite powder and Dicalcium phosphate along with Trace mineral mixture (100 gm/ Quintal of feed).  
Question 6.     Approaches to enhance body weight gain and improve feed conversion ratio
Ans = provide mineral mix 20 gm /kg of feed and vitamin mixture 1gm/ kg of feed. Balanced feeding is must. Try liver tonics through water.
Question 7.      Hormonal and Nutritional approaches to get more kids/ litter and wean more kids/ kindling
Ans =  Ad libitum feeding will take care of the above issues. No need of exogenous Hormones. In each mating, allow 3 services by the same male partner.
Question 8.     Any new topics that could gather the imagination of farmers including some photographs of your esteemed Institute that is doing great services to rabbit farmers
Ans = Rabbit farming needs definite skills; provide all inputs to get good out put. Undergo training from Govt. organizations. Start with minimum rabbits, gain experience and expand. Make own marketing arrangements.

Common constraints in Rabbit Farming

Common constraints in Rabbit Farming:-
(Question raised by Mr.K.L. Johnson of Thrissur,KERALA his email i.d = )
1. Non-availability of quality parent stock of pure breed rabbits. Because of this, unhygienic, poor quality rabbits are sold at a high cost (even up to Rs.1500 per rabbit) by some cheaters. We never encourage the greedy persons

2. Since there is no vaccination to rabbits, improper and inadequate prophylaxis leads to severe mortality in young stock of rabbits (kits and weaners)

3. Basically rabbits are herbivorous animals they need lot of green forages, fodders and grasses. Inadequate roughage and fibre causes mortality in young stock and poor growth in adult stock

4. Animal Husbandry Department is NOT paying attention to rabbit farming, always neglecting the importance of rabbit farming in rural economy

5. Marketing channels are NOT standard and always fluctuating. Because of this cheaters take advantage of the situation and buying rabbits on live weight basis and selling to other parties on UNIT basis to a high cost

6. Ours is a research organization only (SRRC - CSWRI MAnnavanur Kodaikanal), extension activities are limited. Hence extension departments should train the farmers well before they take up rabbit farming.

7. Rabbit farming needs definite skill. It is NOT like other livestock farming. One should be well trained on all aspects rabbit husbandry

8. Rabbits are PRONE for diseases such as Coccidiosis, Mange infection, Mucoid Enteritis, Paresis, Bloat etc. Hence, prophylaxis is must. No cure for the above conditions

9. Caged rabbits need all the nutrients in a balanced form. Deficiency nutrients (minerals and vitamins) adversely affect the overall performance of the rabbits

List continues…

Clarifications for the questions raised by Dr.(Mrs.) H. Dhanalakshmi, Ph.D.,Veterinary Officer

Frequently asked Questions on rabbit farming & diseases:

Clarifications for the question raised by Dr.(Mrs.) H. Dhanalakshmi, Ph.D., Veterinary Officer, Livestock breeding farm, Hesaraghatta, Bangalore- 89 (e-mail:

Are you selling rabbits from your centre (Kodaikanal)?

Yes, @ Rs.300 each. We have White Giant and Soviet Chinchilla breeds of rabbits.

Please write me in detail about the procedure for procurement of rabbits for the government officials and also for the private people from your centre.

Please send your written requirement to us. We will inform the status after getting your requisition.

Since, there is heavy demand for breeding rabbits from our centre, private people have to pay 25% of the cost of rabbits as advance and wait for about 4-6 months.

Case No. 1: The farmer has a capacity of 500 animals. They are healthy. Only thing is kids of age between 21 days to 35 days die suddenly especially after weaning. Otherwise they are healthy. Usually animals die during night. Postmortem and culture and sensitivity revealed that the animals were positive for Salmonella organisms. What will you recommend for this problem? How to overcome this disease?

Answer: The problem is Hepatic Coccidiosis. Remedy = SUPERCOX (or) RANCOX - 100 gm pocket, Dose = 2 gm per litre of drinking water for 5 days to weaner rabbits. It can be given thro feed also, @ 1gm per kg of feed for 5 days. This is compulsory. This drug contains diaveridine and sulphaquinoxaline

Case No.2: Animals are healthy. Only adult animals die suddenly with no symptoms. PM findings revealed Salmonellosis.

Answer: Give tetracycline water soluble powder @ 1gm per litre of drinking water to all rabbits as a routine measure for 5 days every month

Case No.3: Animals die after showing symptoms of extended neck, shivering of legs and sometimes paralysis of legs. What may be the reasons for this type of symptoms? Please recommend the medications or precautionary measures.

Answer: same as case No.1. In addition give B-complex liquid (GROVIPLEX) @ 20 ml per litre of drinking water to all rabbits for 3 days.

Do you recommend HS vaccination in rabbits?

Answer: In India, NO vaccination is followed for rabbits; rather no vaccine is available for rabbits.

Is there any medication/precautionary measure for adult animals getting hind leg paralysis?

Answer: No treatment for hind leg paralysis (i.e. PARESIS). The animal has to be slaughtered at the earliest and the meat can be used for human consumption. Precaution = avoid visitors inside the farm. Also prevent entry of predators and dogs inside rabbitry

Is there any routine medication practices that I should recommend to the farmers to increase the production and reduce the mortality rate?

Answer: Routine medication is RANCOX through drinking water as mentioned in the earlier email

Does coccidiosis flare up under stress conditions?

Answer: Coccidiosis is a menace in rabbits and definitely it will flare up under stress conditions

Case No. 4: Young animals (15-25 days old) die due to unknown reasons. On postmortem, we could find lesions in the lungs i.e., congested lungs. No other lesions could be recorded. What would be your tentative diagnosis and also treatment?

Answer: Tentative diagnosis is Pasteurellosis. Treatment = NIL. Prevention is better than cure. Provide good care to the young rabbits in terms of ventilation, sanitation. Daily observation is needed. Avoid crowding. Provide good bedding material for e.g. coconut coir fibre.
