title: Comparison of ileal digested production of parental rice and rice genetically modified with cowpeas trypsin inhibitor.
abstract: OBJECTIVE
  To compare the ileal digestibility of protein and amino acids in parental rice and rice genetically modified with sck gene.
  
  
  METHODS
  Six experimental swines were surgically fixed with a simple T-cannula at the terminal ileum and fed with parental rice and rice genetically modified with sck gene alternately. The ileum digesta were collected and analyzed for determination of apparent and true digestibility of protein and amino acids.
  
  
  RESULTS
  The apparent and true digestibility of protein was similar in these two types of rice. Except for the apparent digestibility of lysine, there was no difference in the apparent and true digestibility of the other 17 amino acids.
  
  
  CONCLUSIONS
  The digestibility of protein and amino acids is not changed by the insertion of foreign gene, so it can meet the request of "substantial equivalence" in digestibility of protein and amino acids.
