主　　题：Amino acids Sows Soybean meal Standardized ileal digestibility 

摘      要：Background Two studies were designed to determine standard ileal crude protein(CP)and amino acid(AA)digestibility of soybean meal(SBM)from different origins fed to non-pregnant and pregnant *** solvent-extracted SBMs from soybeans produced in the USA,Brazil,and China were *** Exp.1,eight different diets were created:a nitrogen(N)-free diet and 7 experimental diets containing SBM from different origins as the only N *** non-pregnant,multiparous sows were arranged in an 8×8 Latin square design(8 periods and 8 diets).In Exp.2,the diet formula was the same as in *** gestating sows(parity 3)were assigned to 4 different diets in a replicated 4×3 Youden square design(three periods and four diets)in mid-gestation and again in late-gestation *** When fed to non-pregnant and late-gestating sows,the standardized ileal digestibility(SID)of CP and most AAs from different SBM were not significantly different(P0.05).When fed to mid-gestating sows,the SID values for Arg,His,Lys,Phe,Cys,Gly,Ser,and Tyr in SBM 1 were lower than in SBM 4 and 5(P0.05),whereas SID for Leu from SBM 5 was higher than in SBM 1 and 4(P0.05).SID values for Ile,Ala,and Asp from SBM 4 were lower than in SBM 1 and 5(P0.05).Sows had significantly greater SID values for Lys,Ala,and Asp during mid-gestation when compared with late-gestation stages(P0.05).Mid-gestating sows had greater SID value for Val and lower SID value for Tyr when compared with non-pregnant and late-gestating sows(P0.01),whereas non-pregnant sows had significantly greater SID value for Met when compared with gestating sows(P0.01).Conclusions When fed to mid-gestating sows,the SID values for most AAs varied among SBM *** SID values for Lys,Met,Val,Ala,Asp,and Tyr in SBM were affected by sow gestation *** findings provide a cornerstone for accurate SBM use in sow diets.
