| 摘 要： | 通过对9家预混料生产厂家的4%系列猪用预混料的调查研究,以期了解预混料微量元素的含量。调查结果表明,在抽查的9家预混料生产厂家中,共45个产品中铜、铁、锰、锌的自定标准值和实测值都极大超过了中国肉脂型生长肥育猪和妊娠母猪的饲养标准(1986)和美国NRC(1998)建议的猪营养需要量。铅、砷等危害极大的元素须严格的控制。铜、铁、锰、锌等微量元素的大量添加,虽然可以提高猪的生产性能,但会对环境造成极大的危害。

| Abstract: | The microelement content of premix is known according to the investigation on the series 4% premix of nine factories.The investigation result indicates that the standard value and practice value of copper,iron,manganese and zinc in 45 productions exceed the standard value of the meat-fat growth pig and pregnancy sow in China(1986) and the standard value of the pig in USA(1998),the content of lead and arsenic are rigid regulated.Lots of investigations testify that the ability of production is enhanced because of the microelements accession,such as copper,iron,manganese and zinc,but the lots of microelement bring great harms to environment. |
