Etiological analysis of moldy forage poisoning in rabbits in rainy season

Entering rainy and humid season, especially in January, readers around the frequent telephone consultation, rabbit disease multiple, loss is not repeated, symptoms to wither, tremor, paralysis, paralysis, abortion, diarrhea, etc., similar to heatstroke, Before death, it looked like coccidia. However, comprehensive proof of the fruit is mold poisoning. Because of the acute onset, rapid death, large losses and wide range of hazards, the author wrote a warning.

1. Etiological analysis:

Rainy month high temperature, sultry humidity, if the grass stored improperly, easy to produce mycotoxins fermentation, especially Aspergillus flavus. Rabbits once ingested, severe cases immediately onset, light cumulative chronic progressive poisoning. Rabbits of different ages and sexes were all hypersensitive, especially young rabbits and nursing rabbits. Although it is not contagious, it is difficult to cure.

2. Typical symptoms: decreased appetite at the initial stage, listlessness, thin and swollen body, yellow mucosa, increased body temperature, abnormal feces, constipation, diarrhea, foul smell of feces mixed with blood mucus, yellow urine, shortness of breath, difficulty in raising head when head touches the ground, water in mouth, numbness in walking, trembling of limbs, backward collision, weakness of limbs, difficulty in getting up, round eyes, gradual death, similar to heatstroke. Severe cases of limb convulsion, struggle and scream, exhaustion and death, and coccidiosis. Pregnant female rabbits often cause abortion or stillbirth.

3. Diagnosis by autopsy: bleeding of internal organs, bleeding spots in liver, kidney and heart limbs. Liver degeneration necrosis, swelling yellow, texture becomes brittle. Stomach, small intestine mucous membrane congestion and hemorrhage, mucous membrane shedding, pulmonary congestion, hemorrhage, poor blood coagulation or coagulation time is long. No heatstroke abdominal hydrops and pulmonary edema, cerebral congestion lesions and no coccidiosis liver intestinal hemorrhage and white nodules and gallbladder swelling lesions, but bladder urine accumulation, coccidiosis is yellow, and this is red yellow, so the diagnosis of mold poisoning is undoubtedly.

4, prevention and control measures: strengthen forage management, keep clean and dry, regularly check drying, purchase feed, especially forage should be carefully inspected, found mildew refused to purchase. Green materials should be cut and stored in thin stalls. It is strictly forbidden to feed overnight grass. Wet mixed feed should be mixed and fed, and often clean the feed, clean and disinfect the feed tank and drinking water, to prevent retained feed rancidity and mildew. Pellet feed should not be over-processed, generally processed once a day, after processing, it should be stored in bags when drying in the sun, otherwise the feed seems to be pellets, but the heat is not exhausted, it is more likely to deteriorate. In order to prevent feed mildew, we can add mildew inhibitors, such as calcium propionate, sodium propionate, etc., but practice thinks that the prognosis of rabbits is bad. The rabbits were found to be suffering from the disease and immediately stopped feeding the original feed and replaced with fresh fodder. Drinking and inhaling electrolytic multi-dimensional, etc., while oral nystatin, clotrimazole and garlic. Light can be relieved and gradually recovered, heavy can not be saved, death and regret. In short, the key to this disease lies in prevention, once the disease occurs, it is difficult to turn the corner.
