Prevention and treatment of mucinous enteritis in rabbits with abdominal enlargement and drooling fecal tape

Rabbit mucinous enteritis is one of the rabbit intestinal infectious diseases caused by certain serotype Escherichia coli, which is characterized by abdominal enlargement, fecal mucus or watery, salivation, high morbidity and mortality. Rabbit mucinous enteritis is closely related to feeding and management, especially improper feeding, which affects the normal intestinal microflora of rabbits and makes non-intestinal pathogenic Escherichia coli multiply and produce toxins. The disease has no obvious seasonality and can occur in both male and female rabbits. The incidence of the disease is high in young rabbits aged from 1 to 4 months.

Rabbit

1. Clinical symptoms:

The incubation period was 632 hours. The most acute type: there is often no clinical manifestation, and a few hours after the onset, he falls to the ground and dies. Acute type: elevated body temperature, depressed spirit, loss of appetite or cessation of appetite, breathing slightly faster, abdominal dilatation, auscultation intestinal tinnitus, feces dry and sparse, and died within 1-2 days. Subacute: the course of disease is 7-5 days, and the symptoms are typical. In the early stage of the course of the disease, in addition to acute symptoms, feces are grape-shaped and stained with gelatin-like mucus, or yellow to brown watery dung, turbid urine. In the middle of the course of the disease, the body temperature is gradually normal, conjunctival pallor, rough coat, no stool or fishy smell of feces, mucus and thin feces pollute the anus and hind limbs, and the urine is rice soup-like, pink and fishy. In the later stage of the course of the disease, the body temperature is low, the limbs are cold, the mouth is drooling, the feces are black, roll and scream, the head and neck lean back, the hind limbs are stiff, and eventually die of dehydration and exhaustion.

Second, prevention and control measures:

Strengthen feed management and mix feed reasonably. When changing the feed, it must be carried out step by step, not abruptly; do a good job in environmental hygiene at ordinary times, and disinfect the rabbit breeding places and utensils regularly. Once the disease is found, immediately isolate and treat, strictly disinfect the contaminated rabbit cages and appliances, and urgently inoculate the corresponding (such as the isolated) Escherichia coli alumina formaldehyde vaccine.

In drug treatment, suitable antimicrobials such as gentamicin and streptomycin can be selected. When possible, it is best to conduct a drug sensitivity test. For example, streptomycin is injected intramuscularly 20 mg / kg body weight twice a day for 3-5 days, and sulfadiazine is taken orally 15 mg / kg body weight twice a day for 2-3 days, combined with symptomatic treatment such as astringent antidiarrhoea, rehydration, cardiotonic and diuretics to prevent dehydration in rabbits. If young rabbits can be inoculated with anti-Escherichia coli serum which is dominant in rabbit farm, it has better prevention and control effect.
