I. The pathogenesis of Pasteurella rabbits
Many healthy rabbits have Pasteurella in the nasal mucosa and tonsils, but rabbits generally only get sick when the environment deteriorates or their resistance decreases. Such as improper feeding and management, unbalanced nutrition, long-distance transportation, parasitic infection, feed mutation, excessive fatigue, low ambient temperature, humidity, crowding or poor ventilation, etc., it is easy to cause the resistance of rabbits to decline, and Pasteurella take advantage of the opportunity. Invades the rabbit’s body, causing endogenous infection. The feces and secretions of sick rabbits with this disease will excrete toxic bacteria, contaminate the feed, drinking water and utensils in their environment, and then infect healthy rabbits through the digestive tract or respiratory tract. Infection occurs through wounds on the skin and mucous membranes of healthy rabbits under the action of a blood-sucking insect vector.
2. Preventive measures for Pasteurella rabbits
1. Strengthening Feeding management and good health and epidemic prevention measures. Usually pay attention to prevent rabbits from catching a cold; when shearing rabbits, be careful not to cut the skin; regularly quarantine the breeding rabbit farm, and eliminate the positive rabbits in time; when introducing breeding rabbits, isolate and observe the breeding rabbits for a period of time before mixing them; inoculation.
2. Do a good job of cleaning and disinfection. The resistance of Pasteurella multocida itself is weak, and some commonly used disinfection drugs can kill it. Therefore, if you can regularly use 3% Lysol solution or 20% lime milk to disinfect rabbit houses, rabbit cages, venues, etc., and use 2% caustic soda water to wash and disinfect breeding utensils, the occurrence of this disease can be effectively reduced.
3. Immunization. Regularly inoculate rabbits with Pasteurella rabbits propolis inactivated vaccine or rabbit plague + Pasteurella rabbits propolis double inactivated vaccine.
Third, the treatment of rabbit pasteurellosis
If the rabbit If Pasteurella rabbits appear in the colony, it is recommended to eliminate the sick rabbits with obvious symptoms in time. For asymptomatic healthy rabbits, inject them with inactivated propolis vaccine against Pasteurellosis rabbits for emergency prevention, and quickly enhance the immunity of healthy rabbits.
For some sick rabbits with mild symptoms, they can be isolated and treated. They were injected with penicillin, intramuscularly, 50,000 units per kg body weight, twice a day, for 3 to 5 days. Alternatively, they can also be treated with intramuscular injection of streptomycin, 10,000 units per kg body weight, twice a day, for 3 to 5 consecutive days; or tetracycline, chlortetracycline, and oxytetracycline can be given orally to sick rabbits wait for drug treatment.
If high-quality breeding rabbits have acute symptoms of rabbit pasteurellosis, they can be treated with anti-septic serum. Subcutaneous injection of 2 to 3 ml per kg body weight, and then 1 injection every 8 hours. In addition, in order to have a faster therapeutic effect, 400,000 units of penicillin and 500,000 units of streptomycin can be combined intramuscularly.
If it is a chronic disease, penicillin or streptomycin solution can be used to treat the sick rabbit nasally. If the sick rabbit does not have runny nose within 20 days, it can be considered as cured. .
During the treatment of sick rabbits, you can feed more nutrient-rich feeds to the rabbits to improve the resistance of the rabbits. If there are many sick rabbits, an appropriate amount of furazolidone premix can be added to their concentrated feed, and the addition amount is: 1000-2000g per ton of feed.
