Pig food

Nutritional value of soybean meal varies among sources from different countries (EurekAlert!)
Research from the University of Illinois is helping swine producers know what they're getting when they buy soybean meal from different countries. Genetic differences among varieties of soybeans, as well as differences in growing conditions and processing, may affect the nutritional value of soybean meal produced in different places.
I expect the data are better for pig feed than for human food.
