In order to understand the situation of heavy metal residues of the beef industry chain in Yili area of Xinjiang.The heavy metals (Pb, As, Hg, Cr and Cd) in soil, feed and beef of the cattle farm were determined using the atomic absorption spectrometry.The results showed that the heavy metal (Pb, As, Hg, Cr and Cd)contents in soil samples were 0.03-0.20, 3.87-8.30, 0.15-0.23, 0.09-0.48 and 0.41-0.86 mg/kg, respectively.The heavy metal (Pb, As, Hg, Cr and Cd) contents in feed samples were 3.01-18.09, 75.35-94.27, 19.65-24.37, 0.06-1.04 and 1.81-8.46 μg/kg, respectively.The heavy metal (Pb, As, Hg, Cr and Cd) contents in beef samples were 0.23-0.54, 1.22-7.12, 0.28-0.53, 0.01-0.27 and 0.02-0.03 μg/kg, respectively.The correlation coefficient of the heavy metal element between soil and feed, feed and beef, soil and beef were 0.96, 0.99 and 0.98, respectively.It was concluded that the heavy metal (Pb, As, Hg, Cr and Cd) contents in soil, feed and beef of the cattle farms in Yili area did not exceed the standard and that in the soil, feed and beef had the high correlations. 相似文献

为了解和评价新疆肉牛养殖场的环境,对新疆阿克苏和伊犁及塔城地区的肉牛养殖场土壤进行了重金属含量的测定。根据《畜禽场环境质量标准》(NY/T388-1999)等标准和规范,对3地区的8个肉牛养殖场的土壤采用原子吸收法进行重金属砷(As)、汞(Hg)、铅(Pb)、镉(Cd)、铬(Cr)的检测。结果显示,8个肉牛养殖场土壤中总As、总Hg、总Pb、总Cd、总Cr的平均值分别为0.389、0.568、22.708、0.573和149.449mg/kg,均低于《畜禽养殖产地环境评价规范》规定的最高限值。8个肉牛养殖场综合污染指数(P综)值为0.577~0.994,其中伊犁地区2个监测点和塔城地区1个监测点的土壤环境P综为0.7~1,土壤环境质量处在尚清洁水平;其余5个监测点P综均≤0.7,土壤环境处在清洁水平。结果表明,3地区肉牛养殖场的土壤环境均符合畜禽养殖产地环境规范和畜产品安全生产要求。 相似文献

随着人民生活水平及质量的不断提高,公众对动物源性产品安全的重视程度日益增强,重金属元素污染是当今饲料中存在的不安全因素之一,极少量的重金属便可对动物及人体造成危害,因此有必要建立快速、准确的方法用于检测饲料中重金属元素,从源头上防止重金属进入人们的餐桌。分析了重金属元素对动物机体的危害,并介绍了近年来饲料中重金属元素检测的一些方法。 相似文献

In order to study and evaluate the feeding environment of the beef cattle farms in Xinjiang, the contents of heavy mentals in the soil from 8 beef cattle farms in Xinjiang Aksu, Yili and Tacheng regions were tested according to the Field of Livestock and Poultry Environment Quality Standard (NY/T 388—1999).The atomic absorption spectroscopic method was used to determine the contents of As, Hg, Pb, Cd, and Cr.The mean contents of As, Hg, Pb, Cd, and Cr in 8 beef cattle farms soil were 0.389, 0.568, 22.708, 0.573 and 149.449 mg/kg, respectively, and they were all below the upper limit of NY/T 388—1999.The comprehensive heavy metal pollution index of 8 beef cattle farms were 0.577 to 0.994, and the index were 0.7 to 1 of two observation points in Yili and one observation point in Tacheng.The soil environment quality of these 3 farms were at the level of slight cleaning.The comprehensive heavy metal pollution index of other five observation points were ≤0.7, the soil environment was in a clean level.The soil environment of beef cattle farms in these three regions conformed to the standards of livestock for environment quality and safe products. 相似文献

为了全面了解肉牛饲料营养的最新研究进展,作者查阅并总结了2015年关于肉牛饲料营养的国外文献报道,主要从精饲料、粗饲料以及精、粗饲料搭配3个方面进行了综述。精饲料主要包括蛋白质饲料和能量饲料,其中蛋白质饲料的营养研究主要侧重于不同蛋白质饲料对肉牛消化性能、生产性能、酮体特性和肉质以及瘤胃发酵的影响;能量饲料的营养研究侧重于不同类型及加工工艺对肉牛的生产性能、胴体特性以及瘤胃发酵特性的影响;粗饲料的营养研究主要集中于粗料来源及粗料的加工工艺对肉牛生产性能和消化性能两个方面的影响。另外,对精、粗饲料的搭配比例对肉牛生产性能、胴体特性、瘤胃发酵以及采食行为的影响也进行了综述。通过总结和分析肉牛饲料营养的国外研究成果,为中国肉牛业的快速发展提供一定借鉴。 相似文献
