Phosphorous study on soybean meal

Hans Stein

New research indicates the production area of soybeans does not affect phosphorous digestibility in soy meal.

Dr. Hans Stein at the University of Illinois says previous studies show the protein content of soybeans differs depending on where it is grown, but his latest work suggests that isn’t the case for phosphorous.

“There were no big differences in the concentration of phosphorous among soybean meal produced in different regions of the country, and the digestibility of the phosphorous was also not different.”

He tells Brownfield these findings are welcome news for hog farmers because phosphorous is essential to a pig’s diet.

“A pig cannot live without phosphorous.  In fact, if you fed a phosphorous-free diet for a couple of weeks, the pig would start suffering and eventually break bones and could not survive.”

Stein sourced soybean meal donated from crushing plants in northern, eastern and western regions of the U.S.
