I. The incidence characteristics of mycotoxins in rabbits
1. There are obvious seasons Sex: Rabbit mycotoxins mostly occurred in the high temperature and humidity season from July to August;
2. Related to the physiological stage of rabbits: Rabbit mycotoxins mostly occurred in lactating female rabbits, followed by female rabbits in late pregnancy. This condition in pregnant rabbits can lead to miscarriage;
3. It is not infectious;
4. The use of drugs is basically ineffective: antibacterial drugs cannot effectively control the disease, so rabbit mycotoxins After the onset of poisoning, it is likely to cause the death of the sick rabbit.
II. Symptoms of mycotoxin poisoning in rabbits
The clinical symptoms of mycotoxin poisoning in rabbits are mostly acute. Abnormal feces, sometimes constipation, sometimes diarrhea, sometimes with mucus on the fecal ball; some rabbits also show staggering walking, trembling, weakness of limbs, paralyzed as soft as mud, head drooping and difficult to lift, wet nostrils and mouth Symptoms such as round eyes and round eyes; some rabbits have bleeding spots on the ear shell or other parts of the skin; the rabbits have elevated body temperature, shortness of breath, rapid heartbeat, and arrhythmia, mostly progressive 2 to 4 days after the onset Before death, some rabbits will struggle and move their limbs before they die.
Third, preventive measures against mycotoxins in rabbits
High humidity and The right temperature is a must for fungus or mold to multiply. Usually, the temperature is about 30°C, the relative humidity is above 80%, and the moisture content of grains and forage grass is above 14%, which is most conducive to the reproduction and growth of Aspergillus flavus. The vast majority of grains, forages and forages can serve as substrates for Aspergillus flavus. If every kilogram of feed contains 1mg of aflatoxin, it can lead to the death of livestock and poultry. Therefore, mycotoxins in rabbits should be the first priority. The specific preventive measures are as follows:
1. Strictly manage feed: It is forbidden to feed moldy feed to rabbits, scientific storage and management of feed, and special personnel to manage feed to prevent damp and moldy. Peanut skin powder, peanut seedling powder, sweet potato seedling powder and other roughages are relatively easy to mold, followed by wheat bran, which is easy to absorb moisture. In addition, if the pellet feed is not dried in time or stored for too long during the processing, it is also prone to mold.
2. The breeder usually does not pay attention to controlling the feeding amount, and does not clean up the residual feed in the feeding trough in time. The feed or feeding trough is damp and moldy in the feeding trough, and the rabbit accidentally ingests it. It can easily lead to mycotoxin poisoning.
3. In high temperature and high humidity seasons, an appropriate amount of antifungal agents can be added to the rabbit feed, such as propionic acid and its salts, benzoic acid, sodium benzoate, formic acid and its salts, p-hydroxybenzoic acid Esters, citric acid, sodium citrate, calcium lactate, ferrous lactate, fumaric acid and fumaric acid diester, etc., these substances have good anti-mildew effect.
4. Treatment of mycotoxins in rabbits
1. If If a rabbit is found to be poisoned by mycotoxins, immediately stop feeding it the original compound feed, and use fresh forage instead; method of treatment. Supportive therapy: inject 20-40ml of 25% glucose intravenously into the rabbit, twice a day, until the rabbit recovers.
3. Add an appropriate amount of dispersible vitamins to the drinking water of the rabbits, according to the dosage of 1.5 times the dosage in the instructions for use of the drug, for 5 consecutive days. Alternatively, 50-100ml of 10% sugar water can be given orally to the rabbits every day;
4. Subcutaneously inject 0.5-1ml of sodium caffeine to help the rabbits to enhance cardiac function;
5. To help the rabbits to release the poison, you can use 20g starch, add water and boil it into a paste, then add 5-6g of sodium sulfate, and give it to the rabbits. ;
6. Inject 3-5ml of vitamin C into the rabbits every day for detoxification, for 3 consecutive days, and use some hepatoprotective drugs during this period;
7. Feed the rabbits Appropriate amount of nystatin, clotrimazole and allicin and other drugs that are highly sensitive to mold can achieve the purpose of bacteriostasis.
Most of the rabbits can recover quickly as long as they stop eating moldy feed and take antifungal drugs in time. Through the above-mentioned measures, the condition of the rabbits can be effectively controlled after three days of treatment.
