Comparison of Methods for Determining Digestible Amino Acids

Comparison of Methods for Determining Digestible Amino Acids ized AA digestibility values for SBM were generally higher than those for corn and MBM. There were generally no consistent differences in standardized amino acid digestibility values among assays and values were in general agreement, particularly for soybean meal and meat and bone meal. They reported that the standardized values for some amino acids in corn were higher for the PFR than for the PFC and SID assays. The results of the study indicated that all three assays are acceptable for determining the AA digestibility of feed ingredients for poultry.
