An article co-written by USSEC consultant and professor of animal nutrition at the University of Illinois, Dr. Hans H. Stein, was published in early April in the Journal of Animal Science.
The article, “Chemical Composition and Amino Acid Digestibility of Soybean Meal Produced in the United States, China, Argentina, Brazil, or India,” written by Vanessa Lagos, Ph. D. student in the Stein Monogastric Nutrition Laboratory, and Dr. Stein, reported the results of a case study on the effects of origin of soybean meal on the digestibility of amino acids. The study, “Ileal Digestibility of Soybean Meal in Swine,” was funded by USSEC and the Indiana Soybean Alliance.
Dr. Stein concluded his study in July 2016 and discussed his methodology and results at the 2016 U.S. Soy Global Trade Exchange. His team analyzed digestible, metabolizable energy by analyzing the feces and urine of pigs.
“The most expensive part of the diet is the energy,” Dr. Stein stated.
The study showed that U.S. soybean meal had more digestible amino acids than that of other origins, and that soybean meal from the U.S. has greater digestibility and less variability in composition and digestibility.
