目前美国农业部农业研究局、威斯康星大学研究人员，从转基因苜蓿中提取了肌醇六磷酸酶，它可用作非反刍动物如鸡、猪的饲料，使其对磷的吸收提高至４２％。从转基因苜蓿中提取这种酶比传统方法或经发酵处理要便宜。除了含有肌醇六磷酸酶外，转基因苜蓿还富含蛋白质和叶黄素， At present, researchers from the Agricultural Research Service and the University of Wisconsin at the U.S. Department of Agriculture have extracted phytase from transgenic alfalfa and used it as a feed to non-ruminant animals such as chickens and pigs to increase the uptake of phosphorus by 42%. Extracting this enzyme from transgenic alfalfa is less expensive than traditional methods or fermentation. In addition to containing phytase, transgenic alfalfa is also rich in protein and lutein,
