Abstract :
In order to determine of effects of gamma-irradiation on soybean meal chemical composition, this study was carried out. Gamma-irradiation of soybean meal at doses up to 16 kGy could change its protein structure by Create cross linking and proteins bind together and gel formation. Data showed that amount of dry matter, crude protein, fat, ash, crude fiber, acid detergent fibers have no significant difference between treatments (p > 0.05). But the amount of NDF, phytic acid and trypsin inhibitor were treated with various doses of gamma radiation showed a significant difference (p < 0.05). So that, with increasing doses of gamma radiation, significantly decreased levels of trypsin inhibitor and phytic acid. Gamma-irradiation of soybean meal can improve nutritive value of feed stuffs
