Yakın kızılötesı spektroskopısı (NIR) ve ıslak kımya kullanılarak bıtkı ve hayvan yemı materyallerındekı besın içerıklerının karşılaştırmalı analızı

Near Infrared Reflection Spectroscopy is available (NIRS) commercially for use in feed testing laboratories for the assessment of the nutritional content and value of grain and other feeds. About 42 samples were collected in this study traditional chemical methods were used, where the scaling technique was adopted using the kjeldahl device for the purpose of determining the percentage of protein in the samples, and the optical absorption technique was adopted using a spectrophotometer device to measure the percentage of carbohydrates in the samples, and the soxhlet extractor device was used to extract the fat in the samples and determine their proportions. The NIR method was also used for the determination of the nutrients. by using NIRS technique, it was found that the highest percentage of protein in the meat and bone sample was 56 and the low value 6.4 As for the percentage of carbohydrates, where the highest percentage was found in sample wheat screens 72, As for the percentages in fat, where the highest percentage was found in the sample of Corn DDGS 11, and low value of sample macaroni 0.2 while in starch, the highest percentages were found Also in the wheat sample 75, As for the percentages in ash, where the highest percentage was found in the sample of bone meal and meat 29 in which a positive (direct) correlation between the two methods, at a probability level of 0.01 for all materials. by comparing the results of the studied nutrients for each sample, there was little difference between the results obtained by the traditional method and the technical method (NIRS) among most of the samples. Finally, the findings in this study confirmed that (NIRS) is better and more accurate than the traditional method.
