With the continued development of highly accurate and rapid near-infrared reflectance spectroscopy (NIRS) analyses of nutrient profiles of poultry feed ingredients, it is possible to successfully implement NIRS into large-scale commercial formulation programs. In addition, these real-time feed ingredient analyses make use of modeling programs that factor nutrient cost and quality along with bird performance and revenue parameters more applicable. Trouw Nutrition has developed the NutriOpt System, a modular precision-feeding system, which uses NIRS-determined nutrient values of feed ingredients, advanced nutrient analysis, and dynamic modeling. The purpose of the current research was to validate the performance and economic impact of NutriOpt formulation technologies and NutriOpt Broiler Model solutions during a 49-day broiler production period. Relative to broilers fed a consultant-formulated control diet, based on wet chemistry analyzed standard nutrient values for the ingredients, broilers fed with diets formulated using NIRS analyzed nutrient profiles of the ingredients had at least equivalent growth rates and feed-to-gain ratios from 0 to 49 D of age. However, this equivalent or better performance was achieved at lower feed costs and improved profitability. Formulating diets based on the NIRS nutrient values of the ingredients and a model to optimize margin per bird on a live weight basis or to maximize breast meat yield resulted in numerically improved profit margins. Taken together, the results indicate that Trouw Nutrition formulation technologies under certain conditions can be used to reduce formulation costs and improve overall profitability relative to a representative feeding program.

随着高精度和快速近红外反射光谱仪（NIRS）分析家禽饲料成分的营养成分，就可以成功地将NIRS应用于大规模的商业配方计划。此外，这些实时饲料成分分析利用了建模程序，该程序将养分成本和质量以及禽类性能和收入参数都考虑在内。Trouw Nutrition开发了NutriOpt系统，这是一种模块化的精确进料系统，它使用NIRS确定的饲料成分营养值，高级营养分析和动态建模。当前研究的目的是验证在49天的肉鸡生产期间NutriOpt配方技术和NutriOpt肉鸡模型解决方案的性能和经济影响。相对于肉鸡饲喂顾问制定的对照饮食，根据湿化学分析成分的标准营养值，使用NIRS分析成分的营养成分饲喂的肉鸡的生长率和饲料增重比至少为0到49D。但是，以更低的饲料成本和更高的获利能力实现了同等或更好的性能。根据成分的NIRS营养价值和日粮（以活重为基础来优化每只鸡的利润率或最大化胸脯肉产量）的模型来制定饮食，从而可以在数字上提高利润率。两者合计，结果表明，在一定条件下，Trouw Nutrition配方技术可用于降低配方成本并相对于具有代表性的喂养计划提高总体盈利能力。用近红外光谱分析法配制的日粮饲喂的肉鸡，其成分的营养成分至少具有相等的生长速度，饲料的增重比为0至49D。但是，以更低的饲料成本和更高的获利能力实现了同等或更高的性能。根据成分的NIRS营养价值和日粮（以活重为基础来优化每只鸡的利润率或最大化胸脯肉产量）的模型来制定饮食，从而可以在数字上提高利润率。两者合计，结果表明，在一定条件下，Trouw Nutrition配方技术可用于降低配方成本并相对于具有代表性的喂养计划提高总体盈利能力。使用NIRS分析成分饲喂的日粮的肉鸡，其0至49 D年龄段的生长率和饲料增重比至少相同。但是，以更低的饲料成本和更高的获利能力实现了同等或更高的性能。根据成分的NIRS营养价值和日粮（以活重为基础来优化每只鸡的利润率或最大化胸脯肉产量）的模型来制定饮食，从而可以在数字上提高利润率。两者合计，结果表明，在一定条件下，Trouw Nutrition配方技术可用于降低配方成本并相对于具有代表性的喂养计划提高总体盈利能力。
