Abstract :The aim of the experiment was to determine the chemical composition of some feed stuffs used for animal nutrition by chemical and near infrared reflectance spectroscopy insert ignore into journalissuearticles values(NIRS); methods and also find out the relationship between two methods. As materials, 14 different feedstuffs were used in the study. Although there were significant relationships insert ignore into journalissuearticles values(R 2 = 0.931, 0.990, 0.993, 0.990, 0.970, 0.980); between two methods in terms of the contents of moisture, crude protein, crude cellulose, crude fat, and starch and crude ash contents. Although comparison of feedstuffs that were analyzed in terms of ADF and NDF contents, the relationships insert ignore into journalissuearticles values(R 2 =0.329 and 0.339); were found insignificant. As a result, if calibration of NIRS was done accurately for analyzes and also NIRS needs more information in its library for more accurate/precise estimation of nutrition contents. Therefore, this study clearly showed that the chemical composition of diets used for poultry nutrition could be estimated readily and cheaply with the aid of NIRS.
