DSM获得FDA的批准，以获得蛋白毒素降解成分

DSM Animal Nutrition & Healthhas receivedFDAapproval of a new enzyme, fumonisin esterase.

Paige Gott, Ph.D., DSM mycotoxin and Hy•D^®category manager, said fumonisin esterase is for the degradation of fumonisins present in swine feed.

“This is the first mycotoxin degrading ingredient to go through FDA’s Food Additive Petition (FAP) process and will be the first product ever to be approved for degrading fumonisins in feed in the U.S. market,” said Gott.

Mycotoxin survey results released during World Pork Expo

Gott also shared updates on DSM's North America mycotoxin survey at a World Pork Expo press conference on June 9.

Survey results showed mycotoxin contamination trends in U.S. corn ingredients, focusing on the year-to-year changes across the country.

“Among the corn samples tested in our annual survey, 90% of the samples were positive for mycotoxins in 2021, versus 88% in 2020,” said Gott.

“We also identified that type B trichothecenes and Zearalenone increased in prevalence from 2020 to 2021, indicating an increased likelihood of exposure in herds and greater potential for negative effects."

Mycotoxin impact on swine feed performance

Lan Zheng, Ph.D., DSM technical services manager, discussed why it’s imperative now — through an anticipated season of high corn prices — to make sure mycotoxins aren’t affecting swine feed performance.

郑说：“霉菌毒素可以带来猪健康和性能的几种负面结果。”“从生殖损伤到消化系统疾病，疫苗功效降低以及对感染的易感性提高，可能是对猪手术的毁灭性。

"And with high corn prices, it’s imperative right now that feed is working without concern of performance-related losses," she said.

Implement a mycotoxin risk-management program

Gott shared why it's important to implement amycotoxin risk-management programin your operation.

“Proper sampling and analysis are key to a comprehensive mycotoxin risk-management program," said Gott.

"Mycotoxins are not evenly distributed throughout feed, leading to variation in exposure over time. Therefore, routine analysis can provide insights into the types and levels of mycotoxins animals are exposed to.

"With this information, it's possible to develop a customized mitigation strategy to address challenges."
