Fermented soybean meal helps pigs digest the phosphorous in the meal better than conventional soybean meal, University of Illinois researchers have discovered.The fermented meal is considered a promising substitute for fish meal in weanling pig diets because of its protein content, lower cost, and lack of anti-nutritional factors.
"Most of the phosphorus in soybean meal is bound to phytate, so it's not available to pigs,” explained animal sciences professor Hans Stein. "Fermentation releases phosphorus from the phytate molecule."
Previous research by Stein’s group found that pigs digest the phosphorous in fermented corn more easily than that in non-fermented corn.
"If swine producers use fermented soybean meal without phytase, they can use a greater digestibility value for phosphorus than if they use conventional soybean meal. Therefore, they need less supplemental phosphorus from other sources in the diets to meet the pig’s requirements.”Source:
