University of Illinois researchers recently found that pigs digest the phosphorous in fermented soybean meal (FSBM) better than the phosphorus in conventional soybean meal. "Most of the P in soybean meal is bound to phytate, so it's not available to pigs", explained animal sciences professor Hans Stein. Previous research by Stein's group found that pigs digest the phosphorous in fermented corn more easily than that in non-fermented corn. "Fermentation releases phosphorus from the phytate molecule", Stein said.
In this study, Stein and his team looked at whether FSBM offered the same advantage. They observed that the standardized, total-tract digestibility of phosphorus in FSBM is 65.5 percent, compared with 46.1 percent in conventional soybean meal. When the enzyme phytase was added to the diets, the digestibility of phosphorus in FSBM increased slightly to 71.9 percent, whereas phosphorus digestibility in conventional soybean meal increased to 71.4 percent.
