Diagnosis and treatment of Ganmaotong poisoning in rabbits

In October 2005, 120 young rabbits raised by Liu in Fangzheng County, Heilongjiang Province had the symptoms of runny nose and sneezing similar to a cold due to the influence of cold. The rabbits were fed with "Ganmaotong" (human medicine, produced by Zhengzhou Kangli Pharmaceutical Co., Ltd.) with a dose of 1 tablet for every 2 young rabbits. The rabbits were fed at 9 am, 55% of the rabbits were found abnormal at 10:00 in the evening, and 7 died the next morning. Then came to our clinic for treatment, during which 8 died one after another. After systematic examination, it was diagnosed as "Ganmaotong" poisoning, because it is timely, and corresponding measures are taken to avoid greater losses.

1 clinical symptoms

The liver and heart blood smears of dead rabbits were stained and examined under microscope, and no bacteria were found.

Case replication: two healthy rabbits weighing 1 kg were added with Ganmaotong tablets, 8 tablets per kg, 65 grams of food for each rabbit. Poisoning symptoms appeared after 13 hours of observation, and 1 rabbit died 23 hours later. The changes of symptoms and autopsy were consistent with those of the original rabbit.

4 diagnosis

The rabbits who died of the disease had a history of feeding Ganmaotong. The dosage of "Ganmaotong" should be 30 tablets for rabbits weighing 1 kg per day, while the dosage for 1 rabbit in this household is 2 tablets, which is 15 times that of Ganmaotong.

Most of the dead rabbits are strong rabbits, and the phenomenon of grazing for food in this part of rabbits is serious, so there are many diseases and deaths.

Then according to the situation of laboratory examination (omitted), it can be confirmed that the rabbits of this household are poisoned by excessive amount of food "Ganmaotong".

5 treatment

First of all, stop feeding the feed containing "Ganmaotong", supply water to slightly satisfy the symptoms, and add glucose powder, compound vitamin B and vitamin C to drinking water for 3 days.
