In addition to protein content, lower cost, and lack of anti-nutritional factors, fermented soybean meal (FSBM) also meets pigs’ phosphorous requirements.
Recently published work by the Hans Stein group at the University of Illinois (presented at the 44th Nottingham Feed Conference) has found that pigs digest the phosphorous in FSBM better than the phosphorous in conventional soybean meal.
The same group had previously found that pigs digest phosphorus in fermented corn more easily than in non-fermented. The fermentation process releases phosphorous from the phytate molecule making it available to the pig. The traditional method for increasing phosphorous availabily in conventional soybean meal is to add the enzyme phytase to help to release the phosphorus. But when using FSBM the addition of the enzyme is not necessary, because it does not increase the digestibility of the phosphorus any more than using FSBM alone.
