ABSTRACT
<p><b>OBJECTIVE</b>To compare the digestibility of main nutrients in genetically modified rice with double antisense starch-branching enzyme gene and parental rice.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
