Recently, Zhao Bujing, Tianchang Town, Binhai County, telephoned the newspaper “The Pastoral Doctor 110†and reported that his family had a total of more than 500 ducks. The current average weight is 2 to 2.5 kg. The main practice is to raise fish and supplement the feeding of wheat and rice. Daily wheat, Rice was fed at a rate of 6 to 4 and the daily feed was no more than 50 kilograms. However, 4 days after the wheat was fed, the ducks gradually died. So far, 71 ducks have been killed. For spinning, not eating, bloating and so on. He asked: Why did the duck die? How should I treat? Did the dead duck overfeed and drink too much water?
The reporter interviewed Min Wei, director of the poultry research department of the Nanjing Institute of Animal Husbandry and Poultry Research. After learning about the pathogenesis of Zhao Bujing duck, Yu Wei said that the death of the duck may have the following reasons: (1) Storage time of wheat or rice If it is too long or it is stored improperly, it will cause duck aflatoxin poisoning death caused by moldy feed; (2) When feeding ducks, it should not be fed too much wheat, because wheat contains ergot alkaloids, general animal feed contains 0.5% ergot Alkali feed can appear toxic symptoms, clinical manifestations of gastrointestinal diseases and neurological symptoms. The reader thinks that the possibility of ducks eating more bloating and death is relatively small. At present, the feed formula for ducks should be improved first, and the proportion of corn in duck diets should be increased. Generally, the amount of corn added to duck diets should reach 60% to 70%. The amount of wheat added is controlled at about 15%.
In addition, the reporter also interviewed the researcher of the poultry research department of the Anhui Provincial Institute of Animal Husbandry and Veterinary Medicine, Zhan Kai, and Zhan Kai said that according to Zhao Bujing’s statement, he first performed the determination of residues of organophosphorus and other pesticides in wheat, and detected whether it was caused by drug residues. Duck poisoning died. In addition, the duck's digestive function of wheat is relatively poor, and wheat contains some anti-nutritional factors, and is not suitable for long-term overfeeding. In addition, unreasonable farming environment, large temperature difference between winter temperatures, improper immunization, etc. are all likely to cause duck disease, such as duck viral hepatitis, E. coli infection, so it should strengthen feeding and management, timely immunization. In addition, there is no clinical case of ducks dying from bloating caused by eating too much wheat. In addition, the feed for ducks should be dominated by feeding corn, and the use of wheat should be appropriately reduced.
