Why the UA range changed Using the data from the simulation conducted by Havenstein et al. (2003) with “1957” broilers versus “2001” broilers it is possible to estimate the trypsin inhibitor intake of the “1957” birds fed 1957 diets and compare it with the estimate of TI intake by the “2001” birds fed 2001 diets.
