大麦营养价值及在肉鸡饲粮中的应用.

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 the β-glucan and various anti-nutritional factors. Barley β- 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.
