At present, many new features have emerged in the epidemic of rabbits, and farmers must observe carefully, be patiently fed and effectively controlled.
(1) Rabbit lice are still the number one killer of rex rabbits, but clinical atypicalization dominates the mainstream.
In recent years, the disease has apparently been characterized by early age, atypicality, and sporadic symptoms. First of all, the age of onset presents a diversified trend, especially in puppies who have just weaned, as early as about 40 days of age. Secondly, the clinical symptoms and anatomical features are not exactly in line with the typical rabbit palsy. Its main features are depression, loss of appetite, gradual death, and cramps. The necropsy features showed thymic swelling, other symptoms such as pulmonary and tracheal hemorrhage, liver degeneration, renal swelling, rectal jelly-like mucus and anal mucous yellowish embolism, and some have 1 to 2 symptoms. Many of them are not uniform. In addition, rabbits rarely spread in large areas, mostly scattered and localized.
Countermeasures: The disease can only take precautions-based measures. In management, as long as the immunization program is sufficient and timely injection of vaccine can be effectively controlled. The pups were first exempted in 35 days and 40 days, each subcutaneously injected with 2 ml and boosted once after 20 days. After the injection 3 times a year. The effect of injection single seedlings is best, and the seedlings have certain effects on the immunity of rabbits; there are following three treatment approaches after the occurrence of rabbits lice: injection of hyperimmune serum, the quickest effect, the best effect, but the high cost, lack of supply; injection of interferon , Interfering with the replication of rabbit prions, effective in the early stages of disease. However, after the epidemic, there is still a need to inject vaccines; rabbits and quail vaccines are used for emergency prophylaxis, with 2 to 3 ml each, gradually controlling the condition after 3 days, and generating strong immunity after 7 days.
(2) The three diseases of infectious rhinitis, ringworm and foot dermatitis are the three major problems that plague Rex rabbits. Effective control cannot be ignored.
1. Infectious rhinitis: Effectiveness of drug use, withdrawal of drug relapse, and infective rhinitis in rabbits are the result of a combination of multiple pathogens, including Pasteurella multocida and Borrell bacteria. It is one of the major infectious diseases in rabbits. The disease has high morbidity, strong infectivity, occurs in four seasons, is susceptible to small and large rabbits, has little effect on vaccines, is difficult to control, has a low cure rate, has a high recurrence rate, has a long duration, and is prone to deterioration and secondary infections. It is one of the most stubborn diseases in production.
Countermeasures: Many drugs have an effect on the prevention and treatment of infectious rhinitis. Chinese and Western combination of drugs - nasal anal net best. However, it cannot be eradicated. The rate of relapse depends on the environmental improvement. Other methods recommended: penicillin and streptomycin, each of 20,300 units per kilogram of body weight, mixed with intramuscular injection. Daily 2 times for 3 consecutive days; intramuscular injection of 20,000 units per kilogram body weight 3 times a day for 3 days; kanamycin, 15 mg/kg body weight 2 times a day for 3 consecutive days; per kilogram of body weight Intramuscular injection of ofloxacin 4 mg or ciprofloxacin hydrochloride 3 mg twice daily for 3 to 5 days.
2, rickets: a wide range of invasion, high incidence, interactive infection, control more difficult.
Rabbit plague, also known as rabbit rickets, is an ectoparasitic disease caused by parasites or ticks on rabbits. The disease is widespread and has a high incidence. The disease is highly contagious. If the treatment is not timely, the sick rabbit can die due to gradual weight loss and weakness, and the damage is very serious.
Countermeasures: Do not buy sick rabbits with deafness. Keep cages dry and often sterilize rabbit cages with flames. Each quarter was fed with 5% triclosan and 2% aqueous solutions of trichlorfon for 1 time. When the rickets occur, apply the affected part to the rabbit with 5%-10% dicofol oil solvent and aqueous solution in time, and repeat it 7 days later. At the same time, the rabbit cage and the site were sprayed with a 5% aqueous solution to incinerate the grass. The rabbits had a net application of the affected area once. After a severe 7 days, they could be used repeatedly to kill the eggs. Oral Wei Jia (avermectin) orally taken, 0.1 g per kilogram of body weight, 7 to 10 days repeated medication once. Insecticides require instructions for intramuscular injection. 2% trichlorfon solution wash the affected area, avoid washing with soap or detergent. After washing, dry it with dry cinder or dry sand to prevent poisoning.
3, Rex Rabbit foot dermatitis: common multiple, although not immediately die, but affect the breeding value of rabbit species and commercial rabbit fur quality.
Rabbits are reluctant to exercise, loss of appetite, loss of appetite, slowness of movement, difficulty in bearing the weight of the lower extremities, frequent exchanging of supportive weight on the extremities, and occasional arching of cages. Examine the rabbit's foot and check for hair loss. Erythema, suppuration, ulceration, ulceration and irritable bowel formation after prolonged bleeding. Some inflammatory epithelial dermis can produce secondary bacterial infections.
Countermeasures: Strengthen feeding and management, pay attention to the cleanliness of the rabbit cages, clean the bottom of the cage thoroughly and regularly spray with 0.3% peroxy acetic acid spray; rabbit cage bottom is best made of bamboo. The cage bottom should be smooth, the nails should not protrude, and there should be no sharp objects in the cage; the immunization should be performed with injection of Staphylococcus seedlings, 2 ml per rabbit, and immunization twice a year. At the time of treatment, the rabbits were first placed in a cage covered with dry, soft grass (or other bedding material). Repeat the winding around the lesion with a rubber plaster (try to relax the wound), then gently press with your hand. Compaction overlap adhesive plaster, self-healing 20-30 days; headquarters shearing and disinfection, remove necrotic tissue, 3% peracetic acid cleaning, rubbed sulfapyridine, oxytetracycline ointment, etc., when the ulcer began to heal, can be coated Wipe 5% gentian violet solution once a day; severe external use of sterile gauze bandage is good, at the same time injection of green, streptomycin 100,000 units each day sooner or later, until healed; severe cases immediately eliminated.
