The Effect of Fermented Soybean Meal Supplementation on Nutrient Apparent Total Tract Digestibility and Ileal Digestibility in Weanling Pigs

Kim, In-Ho

Abstract Text: Fermentation processes have been used to prepare traditional soybean foods, making them highly digestible and nutritious. Five pigs [(Landrace × Yorkshire) × Duroc, BW = 17.0 ± 0.3 kg] were used in a 5 × 5 Latin square design with 5 diets and 5 periods to evaluate the effect of fermented soybean meal on apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID). Dietary treatments were: SBM, soybean meal; CJY, fermented soybean meal by yeast; CJYB, fermented soybean meal by yeast and Bacillus; CJC, canola meal; and FSBM, Soytide, fermented soybean meal by Bacillus subtillis. Pigs fed with CJYB or FSBM had higher ATTD and AID of nitrogen (P<0.05) than those fed CJC, and pigs fed with CJYB or FSBM had higher (P<0.05) AID of nitrogen than those fed with SBM. Pigs fed FSBM and CJYB had higher (P<0.05) ATTD of leucine, lysine, phenylalanine, glutamic acid, tyrosine and total essential amino acids (EAA) compared with those fed CJC. The AID of total EAA of CJYB and FSBM were higher (P<0.05) than CJC, and the AID of lysine and phenylalanine in FSBM was higher (P<0.05) than that in CJC or SBM. The AID of glutamic acid, serine and total non-essential AA of CJYB and FSBM treatments were higher (P<0.05) than CJC treatment. Pigs fed with FSBM had higher (P<0.05) AID of asparatic acid and glycine compared with those fed with CJY or CJC. Overall, the AID of total AA in CJYB and FSBM treatments were higher (P<0.05) than that of CJC treatment. In conclusion, results indicate that compared with canola meal, fermented soybean meal by yeast and Bacillus or Bacillus subtillis can improve AID and ATTD of nitrogen, increase ATTD of EAA and AID of total AA in weanling pigs.
