Abstract
The determining and comparing of nutrient composition of some alternative feeds with chemical analysis and near infrared reflectance Spectroscopy (NIRS) techniques was purposed in the research. Cotton leaf, cotton seed, mulberry leaf, olive leaf, carob, artichoke leaf, and crop residue of tobacco were used as alternative feed materials. The differences in the crude protein (CP) values of feeds analysing with two methods was lower compared to the differences of the other nutrient values of feeds. The crude fibre (CF) content of carob was determined similar in both technique, while the ash, ether extract (EE), NDF, ADF, CP and CF (P<0.05) content of carob were determined differently. There were no (P>0.05) differences content of ash, EE and CP of olive leaf, mulberry leaf and cotton seed between two technics. As a conclusion, nutrient contents of some plant materials considered as alternative feed were determined by the chemical and NIRS methods. But, for the results analyzing by NIRS method in order to give the results that are closer to the values analyzing by chemical methods, further researches containing much more feeds samples and also covering the different physiology stage of plant is needed to enrich the results of this study.
Özet
Bu çalışmada; bazı alternatif yemlerin besin madde kompozisyonunun kimyasal ve Spektroskopik (NIRS) yöntemlerle belirlenmesi ve karşılaştırılması amaçlanmıştır. Materyal olarak; pamuk yaprağı, çiğit, dut yaprağı, zeytin yaprağı, keçiboynuzu, enginar yaprağı ve anızlık tütün kullanılmıştır. Her iki yönteme göre analiz edilen yemlerin ham protein (HP) değerleri arasındaki fark, diğer besin maddelerininkine göre daha düşük bulunmuştur. Keçiboynuzunun ham selüloz (HS) içeriği her iki yöntemde de birbirine yakın değerler (P>0.05) verirken; asit deterjanlarda çözünmeyen lif (ADF), ham kül (HK), ham yağ (HY), nötral çözücülerde çözünmeyen lif (NDF) (P 0.05). Araştırma sonuçları değerlendirildiğinde NIRS metoduyla elde edilen sonuçların, kimyasal metotla elde edilen sonuçlara daha yakın değerler verebilmesi için, bundan sonraki çalışmalarda bitkilerin değişik fizyolojik dönemlerini de kapsayacak ve örnek sayısının fazla olması önemlidir
