在饲料中适当添加蛋氨酸、赖氨酸等可减少畜禽粪便对环境的污染。因此,未来几年内饲用氨基酸类的市场需求将不断增长,各公司纷纷进行扩建。目前,全球蛋氨酸的市场需求量为46.5万t/a,年均增长率为3％,中国则高达7％～8％。不过目前蛋氨酸市场没有太大起色,亚洲市场蛋氨酸价格已降至不足2美元/kg,因此各公司在扩建的同时力求降低生产成本。赖氨酸全球需求量为60万t/a,2005年可望达到85万t/a。全球苏氨酸的需求量约为3.3万t/a,其需求的增加可同时带动赖氨酸的消费。
Appropriate dietary methionine, lysine, etc. can reduce livestock and poultry on the environment pollution. Therefore, the market demand for amino acids for feeding in the next few years will continue to grow, and various companies expand one after another. At present, the market demand for methionine in the world is 465,000 t / a, with an average annual growth rate of 3% and in China as high as 7% -8%. However, the current methionine market is not much improvement, methionine prices in Asia have dropped to less than 2 US dollars / kg, so companies in the expansion while trying to reduce production costs. Lysine global demand of 600,000 t / a in 2005 is expected to reach 850,000 t / a. The global demand for threonine is about 33,000 t / a. The increase in demand can simultaneously drive the consumption of lysine.
