摘　　要：随着饲料原料价格上涨,玉米、小麦等传统谷物的持续供应已成为一项挑战。大麦已被认为是一种优秀的能量替代原料。大麦的营养价值和成分与玉米接近,蛋白质与氨基酸较高,但是含有β-葡聚糖等各种抗营养因子以及营养成分和质量的可变性等一些限制因素,大麦在家禽日粮中的使用率仍然相对较低。大麦中的β-葡聚糖,主要通过增加动物体内食糜黏度,从而影响营养成分的吸收。肉鸡养殖过程中,通过使用酶制剂、调整生产工艺以及对大麦进行发酵处理等方法,降低大麦中抗营养因子对消化率的影响,从而提高大麦在肉鸡饲粮中的使用量。With the rising of the price of raw materials,the sustained supplying of traditional grains such as corn and wheat are going to be a challenge.Barley has been recognized as an excellent energy substitute material.The nutritional value and composition of barley is similar to the corn,with higher protein and amino acids.But the usage rate of barley in poultry diets is still relatively low because of theβ-glucan and various anti-nutritional factors.Barleyβ-Glucan mainly affected the absorption of nutrients by increasing the viscosity of chyme in animal.During the breeding process,methods such as using enzyme preparations,adjusting production processes,and fermenting barley were used to reduce the impact of anti-nutritional factors on digestibility,thereby increasing the amount of barley used in poultry diets.
