【 摘 要 】

This study was conducted to evaluate effects ofinfrared irradiationfor60, 90, 120 and 150 sonstarchruminal degradability and chemicalcompositionofbarley grain. Three ruminally fistulatedramswere used tomeasurein saccodegradation.There wasa linear increaseon DM chemical compositions irradiatedbarley grain (P<0.05). Infraredirradiation decreasedpotentially degradablefraction andconstant degradation rate of starch(P<0.001).Effective ruminal degradability of starch for irradiated barley grain decreasedlinearly(P<0.001) as irradiation time increased until 90. It was concluded that infrared irradiation for 90 s could decrease starch degradability of barley, a benefit characteristic of barley feeding in ruminant nutrition.
