The disease is the most serious disease in the production of rex rabbits, especially the morbidity and mortality of young rabbits aged 2 to 3 months. Causes of diarrhea are mainly caused by two aspects, one is caused by pathogenic bacteria such as E. coli, Salmonella, Sesbania, Bacillus subtilis, parasites, etc.; second, due to improper feeding and management, causing indigestion or gastroenteritis type Diarrhea, such as sudden changes in feed, feed forage and mildew, deterioration of drinking water, feeding with dewy grass or indigestible feed, rabbit house cold and humid, etc., can cause diarrhea. Control methods: 1 to strengthen the feeding and management, it is strictly prohibited feeding corrupt spoilage feed, reasonable feeding of juicy, green feed, to maintain the health of the rabbit house. 2 When the rabbit is found to have decreased appetite, abdominal distension, and lack of energy, it is necessary to reduce or stop the supply of concentrate, feed a small amount of green vegetables or easily digestible feed, and immediately feed half of oxytetracycline per tablet. 3 times. The bottom ash or charcoal ash can be added to the weaned rabbit's concentrate. 3 In China, diarrheal diseases in rabbits are mostly caused by Clostridium perfringens type A, manifested as acute diarrhea, fecal samples are black jelly-like. There is currently no effective treatment for this disease. For rabbits that have already developed the disease, clostridium perfringens hyper-immune serum can be injected together with anti-inflammatory and fluid replacement to control the development of this disease. At the peak of onset, healthy rabbits were injected with inactivated aluminum hydroxide of Clostridium perfringens, and the results were good. 4 When rabbits have already started diarrhea and no etiology has been identified, comprehensive mixed drugs can be used for treatment: sulfaquinone, chloramphenicol, and lanthanum nitrate are mixed and powdered and fed. At the same time intramuscular chloramphenicol injection (1 ml each time, the amount of rabbits halved), 2 times a day. When diarrhea has stopped, continue to administer for 2 to 3 days.
Caused by Pasteurella multocida, young rabbits and lean rabbits are most susceptible to infection. If you do not isolate the treatment in time, it can cause a large number of deaths in the short term. Symptoms: The incubation period of the disease varies in length. Acute cases usually die within 10 hours of onset. There are no obvious clinical symptoms: chronic cases are not easily distinguishable from colds at the onset. Rabbits often use the front paws to rub the external nostril, upper lip, nostrils swelling, and then, ear, eye and subcutaneous infection, there purulent conjunctivitis, otitis media, subcutaneous abscess, mastitis and other complications. Treatment: 1 penicillin, streptomycin 100,000 units mixed intramuscular injection, 3 times a day, once every 3 to 5 days: 2 oral administration of sulfamethazine, 0.05 to 0.2 grams per kilogram of body weight, 2 times a day, even for 3 ~ 4 days. Prevention: Quarantine regularly with a brilliant green solution (available at pharmacies), use a 0.2 to 0.5% brilliant green solution for nasal drops, 2 to 3 drops per rabbit, observe if there is purulent mucus outflow from the nostrils after 18 to 24 hours. It is a negative reaction; injection of rabbit aluminum hydroxide formaldehyde formaldehyde vaccine to prevent injection; in the feed sulfa drugs, such as 100 kg of feed mixed with sulfa oxalin 22.5 g, have a better preventive effect.
A protozoan disease caused by parasites of various species of Eimeria parasitizing in the epithelial cells of the gut or bile ducts. Symptoms of suffering from rabbits: Puppies less than 60 days of age often present with an acute process, suddenly fall sideways when the disease occurs, head backwards, quickly died after oozing. Chronic disease loss of appetite. Abdominal distension, diarrhea, fecal contamination of the anus. 1 to 4 months old young rabbit infection rate is high, the mortality rate of 80 to 85%; adult rabbits often no obvious symptoms after infection, but often emit coccidia eggs pollute the environment and expand the infection. Commonly used therapeutic drugs include chlorpheniramine, dichlorure, rabbit globules, sulfamethazine, and the like. Each kilogram of concentrate is mixed with 300 mg of chlorophenylhydrazine (150 mg after 1 to 2 weeks), which has a significant effect on coccidiosis in rabbits. Preventive measures: Remove feces and urine once a day. In the spring and summer rainy season, the rabbits are fed with 150 mg of chlorobenzene per kilogram of concentrate. This can basically control the disease.
