我国饲料级赖氨酸的生产还不能满足饲料生产的需要,大部分产品需从国外进口。2000年国内L-赖氨酸需求量约为7万t,而产量不足2万t。大量的低价进口产品导致国内饲用赖氨酸市场几近饱和。作者指出,国内企业应把重点放在开发赖氨酸的其他用途上,例如,挖掘赖氨酸的医用价值。目前已有3种L-赖氨酸及其复配药获得国家药监局批准使用。 The production of feed-grade lysine in China cannot meet the needs of feed production, and most of the products need to be imported from abroad. In 2000, the domestic demand for L-lysine was approximately 70,000 tons, while the output was less than 20,000 tons. A large number of low-priced imported products led to a near saturation of the domestic feed lysine market. The authors pointed out that domestic companies should focus on other uses for the development of lysine, for example, the medical value of lysine. At present, three L-lysine and its compound drugs have been approved for use by the State Food and Drug Administration.
