抽样调查北京地区猪场饲料及饲料原料赭曲霉毒素A污染状况
Sampling and Investigating Ochratoxin A Contamination of Feeds and Feedstuffs from Pig Farms in Beijing Area
摘要
Abstract
This study was conducted to determinate the ochratoxin A (OTA) content in feeds and feedstuffs by means of immunoaffinity column clean-up and high-performance liquid chromatography (HPLC) for knowing the OTA contamination situation in feeds in Beijing area. One hundred and thirty-one feed samples including 14 corn samples, 11 soybean meal samples, 13 bran samples, 17 distillers dried grains with solubles (DDGS) samples and 76 complete pig feed samples from 15 pig farms located Changping district, Daxing district, Yan-qing district, Pinggu district and Shunyi district in Beijing area were collected to determinate the content of OTA. The results showed that the detection rates of OTA in corn, soybean meal, bran and DDGS were 92. 86% , 63. 64% , 76. 92% and 100. 00% , and the average contents of OTA were 22. 12, 10. 81, 7. 78 and 22. 46 (xg/kg, respectively. The OTA content in corn was exceeded and the over standard rate of OTA was 7.14% . The detection rates of OTA in complete pig feeds (piglet, weaner piglet, growing pig, grow-fin-ishing pig, pregnant sow and lactation sow) were 100. 00% , 85. 70% , 85. 70% , 94. 44% , 90. 00% and 100. 00% , and the average contents of OTA were 4. 39, 15. 74 , 11. 66, 13. 07, 47. 75 and 15. 40 (xg/kg, respectively. The OTA content in pregnant sow feed was exceeded and the over standard rate of OTA was 20. 00% , while the OTA contents were lower in the other complete feeds. The results indicate that OTA contamination extent is different in kinds of feeds and feedstuffs. The average levels of OTA in corn and pregnant sow feed are exceeded, but those in the other complete pig feeds and feedstuffs are not exceeded.
