title: [The main nutrients digestibility of genetically modified rice and parental rice in the terminal ileum of pigs].
abstract: OBJECTIVE
  To compare the digestibility of main nutrients in genetically modified rice with double antisense starch-branching enzyme gene and parental rice.
  
  
  METHODS
  Seven Wuzhishan healthy adult barrows were surgically fitted with a T-cannula at the terminal ileum. After surgery, seven pigs were randomly divided into two groups, and fed genetically modified rice and parental rice by a crossover model. Ileal digesta were collected for analysis of main nutrient digestibility.
  
  
  RESULTS
  The apparent digestibility levels of protein in genetically modified rice and parental rice were 69.50% ± 4.50%, 69.61% ± 8.40%, respectively (t = 0.01, P = 0.994); true digestibility levels of protein were 87.55% ± 4.95%, 87.64% ± 9.40%, respectively (t = 0.01, P = 0.994); fat digestibility levels were 72.86% ± 0.34%, 77.89% ± 13.09%, respectively (t = 0.95, P = 0.378); carbohydrate digestibility levels were 72.92% ± 7.43%, 92.35% ± 5.88%, respectively (t = 4.27, P = 0.005). The apparent and true digestibility of 17 amino acids had no significant difference in the two rice.
  
  
  CONCLUSIONS
  Carbohydrate digestibility in genetically modified rice was significantly lower than that in non-genetically modified rice, other main nutrients digestibility in the two rice have substantial equivalence.
