摘要: 1. The aims of this study were to investigate the potential near infrared reflectance spectroscopy (NIRS) predict chemical and physical characteristics wheat also nutritive value for broiler chickens. 2. A total 164 samples, collected from a wide range different sources (England, Northern Ireland Canada), varieties years, used in study. 3. Chemical parameters measured included specific weight, thousand grain vitro viscosity, gross energy, nitrogen, neutral detergent fibre (NDF), starch, soluble non-starch polysaccharides (NSP), lysine, threonine, amylose, hardness, rate starch digestion protein profiles. 4. A 94 samples selected inclusion three bird trials at 650 g/kg typical UK starter/grower diet. Birds housed individual wire metabolism cages 7 28 d offered water food ad libitum. Dry matter intake (DMI), live weight gain (LWG...
