Coccidiosis is the most common and serious harm rabbit of a parasitic disease. Rabbit coccidiosis can cause a large number of young, young rabbits incidence of death, the growth rate decreased, decreased immunity, susceptible to other diseases, increased production costs, a significant decline in economic efficiency, seriously affect the development rabbit industry. Therefore, we must take seriously the rabbit coccidiosis, to take preventive measures rabbit coccidiosis. The disease pathogen Eimeria rabbit, rabbit parasites on 14 species, mainly in Sri Lanka's Eimeria, perforation Eimeria, Eimeria large and medium-sized Eimeria, caecum Eimeria like. Coccidia are single cell parasite. Trophozoites coccidia rabbit intestinal epithelial cells or bile duct epithelial cells parasitic, reproduction, after the formation of oocysts excreted in feces, contaminated feed, water, utensils, bedding and rabbit cages. Rabbit coccidia oocysts at a temperature of 20 ℃, 55-75% humidity ambient, after 2-3 days or develop into invasive oocysts, this would have infectious oocysts. Susceptible rabbits swallowed invasion oocysts after the onset of infection. Oocysts strong resistance to the external environment, can live in the water for two months in moist soil can survive for more than a year. It is very sensitive to temperature, 20 minutes at 60 ℃ water death; 80 ℃ death in water 10 minutes; boiling water for 5 minutes to die. Oocysts below -15 ℃ will freeze to death, but the general chemical disinfectants kill them very weak. According to the site of coccidia parasite, rabbit coccidiosis can be divided into two categories: coccidia parasites in the liver called coccidiosis, called intestinal parasites in the intestinal epithelium ball of coccidiosis hepatic biliary epithelial cells within the cell. However, in clinical encounter often mixed infection of these two types of coccidiosis. 1. The popular features of the disease can occur throughout the year, the rainy season in the South often show peak incidence; in the north in summer and autumn, more hair, showed endemic. All varieties of rabbits are susceptible, after weaning to 3 months old rabbit susceptible, the mortality up to 50%. General adult rabbits infected with the parasite, few incidence of death, but it can discharge oocysts are important source of infection. 2. Symptoms of coccidiosis incubation period of 2 to 3 days or longer. Liver coccidiosis symptoms of mental fatigue, loss of appetite, failure to thrive, weight loss, liver tenderness, anemia, visible mucous membranes pale, some jaundice. Intestinal coccidiosis was mostly acute after, before the onset of young rabbits eat forage that is suddenly no abnormal performance against the failure, limb spasms paddling, head back, screaming, rapid death, or may be temporarily restored, the interval a period of time, repeat the above symptoms, and ultimately death. Chronic intestinal coccidiosis performance of physical deterioration, loss of appetite, bloating, diarrhea, abnormal urination, wet hair near the base of the tail, yellow. 3. coccidium dead rabbit liver pathology necropsy necropsy was swollen liver, liver surface visible yellow-white nodules, ranging in size, hard, or liver surface shows a large blister-like lesions, there are more translucent liquid . Nodules or blisters are a large number of oocysts. Swollen gallbladder, bile thick, sampling smear on bile duct, gallbladder mucosa, can be detected oocysts. Pathological changes of intestinal coccidiosis mainly in the intestinal tract, intestinal vascular congestion, intestine tympany, intestinal congestion or bleeding, duodenal dilatation, hypertrophy, congestive or hemorrhagic mucosal inflammation in the small intestine filled with gas and a lot of mucus. Oocyst detection as the main basis for judgment. Acute cases sometimes naked eye can not find lesions, oocyst examination also difficult to find, to make a diagnosis based on clinical symptoms. Chronic, there are many large needle cap and small yellow-white nodules on the intestinal wall suppurative, necrotizing lesions, nodules containing a large number of coccidia oocysts. 4. Prevention: ⑴ Tushe building should choose sunny, Gaozao place and to keep clean environment. ⑵ should wash utensils cleaned and disinfected, especially rabbit cage cage floor regularly with a flame disinfected to kill oocysts. ⑶ to 3 months after weaning rabbits using drugs to control coccidiosis, and regardless of the season. Commonly used drugs and the prevention of coccidiosis usage: diclazuril broad spectrum benzeneacetonitrile anticoccidial drugs per 100 kg of feed mixed with 1 / kg Diclazuril premixes 100 grams.
