无公害生猪生产矿物元素使用现状研究 摘要：本研究为无公害风味猪肉生产集成配套技术中的子项目，主要研究无公害猪肉生产中矿物元素的使用现状。本研究选择平均体重为70.00(1.87Kg健康的DLY商品猪30头，随机分为对照组（基础日粮）、试验I组（1000g/t植物精油））利用原子吸收光谱饲料、肉、肝、血、粪、尿和水铅（Pb）、镉（Cd）、铁（Fe）、铬（Cr）、锌（Zn）和铜（Cu）含量he application research of mineral elements in Pollution-free pig production Abstract：This study was one of the pork production integrated supporting technology flavor in the component. The application of trace elements in pollution-free porkproduction was studied. This study was choiced 30 DLY pigs for 70.00 ( 1.87 Kg that， randomly were divided into the control (basal diet)， trial I (1000 g/t plant essential oil) and trial II (2000 g/t) of feeding trials. After testing， each group 5 pigs were randomly choiced to test and evaluation of slaughter the meat. The feed sample， pork， liver sample， blood， urine sample， dung and water samples were collectedto determine the content of Pb， Cd， Fe， Cr， Zn， Cu by atomic absorption spectrometer.The research results showed that feed of the minerals elements in accord with national pollution-free some production feed health index standard. Flesh of Cr andCd content accord with national pollution-free pork production health index nationalstandards， but Pb more than standard； In drinking water Fe， Cu， Zn， Pb and Cd and Crs content were more than national drinking water hygiene indexes regulation， shows that drinking water quality was pollution-free pig production special need to control the key point； The slaughterhouse waste were used as organic fertilizer use commercial， the environmental impact meet national standards.
