Abstract

The zearalenone contents in feeds and feedstuffs were determined using immunoaffinity-HPLC method in this study for knowing the zearalenone contamination situation in feeds and complete feeds of pig farms in Beijing area. Fifty-five feedstuffs which were corn, soybean meal, bran and distillers dried grains with solubles (DDGS) and seventy-six complete pig feeds were collected from 15 pig farms located in Changping district, Daxing district, Yanqing district, Pinggu district and Shunyi district in Beijing area, and the zearalenone contents were determined. The results showed that the detection rates of zearalenone in corn, soybean meal, bran, DDGS and complete feeds were 100.00%, 54.45%, 100.00%, 100.00% and 58.88%, the over standard rates were 0.00%, 0.00%, 0.00%, 41.18% and 0.00%, and the average contents were 109.08, 9.19, 14.92, 882.68 and 58.88 μg/kg, respectively. The results indicate that there are differences in zearalenone contents among different kinds of feeds and feedstuffs. The average content of zearalenone in DDGS is exceeded, but average contents in complete pig feeds and other feedstuffs such as corn, soybean meal and so on are not exceeded.

Key words： feedstuff; zearalenone; mycotoxin; contamination
