Abstract
This study aims to determine the crude protein and metabolizable energy values in ruminant mixed feeds based on the measurements obtained from Near Infrared Reflectance Spectroscopy (NIRS) device. The mixed feeds used in the study were produced in Balıkesir. Reference analyses were determined by making chemical analyses of mixed feed samples used in the study. Metabolic energy value of mixed feed samples was calculated by using the determined nutrient values in equations. Portable NIRS device was used in the study. The relationship between estimates obtained from NIRS device and reference values was statistically evaluated. In regression analysis, R2 value was found as 0.0064 for crude protein while it was 0.9397 for metabolizable energy. It has been demonstrated that the NIRS method is a fast, reliable and good estimation method for quantitatively determining the metabolic energy value in ruminant mixed feeds.

Summary
Energies are transformed into one form to another transformed into heat energy. Green plants store the physical energy energy cannot be transformed into other forms of of the sun by converting it into chemical energy. The chemical energy (gross energy) in the Humans and animals transform chemical energy in feed can be determined by the heat energy plants into biochemical energy (ATP) by released as a result of the burning of the feed biochemical reactions (oxidation). Energy is not substance in the calorimetry bomb. Energy energy is obtained by removing the energies of which is an abstract concept can be defined feces, urine and fermentation gases (methane) as the ability of the body to work. There are from gross energy (Kirchgessner, 1985). Various forms of energy and these forms can be There are from gross energy (Kirchgessner, 1985). various forms of energy and these forms can be
