Özet
Bu çalışmada iki ve üç fazlı üretim sistemlerinden elde edilen pirinanın kimyasal bileşimi ve in vitro gaz üretimi ile rumen içi fermentasyon özelliklerinin belirlenmesi amaçlanmıştır. Bu amaç doğrultusunda üç ve iki fazlı zeytinyağı üretim yapan tesislerinden yaş çekirdekli, kuru çekirdekli ve kuru çekirdeksiz pirina örnekleri temin edilmiştir. Çalışmadan elde edilen bulgulara göre pirina örneklerinin kuru madde (KM) içeriklerinin faza ve pirina tipine göre önemli düzeyde değiştiği belirlenmiştir (P≤0.05). Kuru çekirdeksiz pirina örneklerinin, ham protein (HP) içeriği bakımından diğer pirina (KM’de % 5,63) örneklerinden önemli düzeyde daha düşük ortalamaya sahip olduğu bulgulanmıştır (P≤0.05). Kuru çekirdeksiz pirina örneklerinin diğer pirina örneklerinden daha düşük asit çözücülerde çözünmeyen lignin (ADL), kondanse tanen (KT) ve toplam fenolik bileşen (TFB) içeriğine sahip olduğu belirlenmiştir (P≤0.05). Buna karşın kuru çekirdeksiz pirina örneklerinin, diğer pirina örnekleriyle kıyaslandığında 96 saatlik kümülatif gaz üretimleri, organik madde sindirilebilirlikleri (OMS) ve metabolize olabilir enerji (ME) içerikleri bakımından daha yüksek ortalamaya sahip olduğu belirlenmiştir (P≤0.05). Sonuç olarak kuru çekirdeksiz pirinanın ruminant beslemede kullanılması önerilebilir ancak HP içeriği düşük olduğundan rasyonun proteince desteklenmesi gerekmektedir.
Abstract
This study was conducted within the borders of Çanakkale Province Yenice (Ahiler village-P1) and Ezine (Kızıltepe village-P2)and formation of two soil profiles on andesitic rocks under different precipitation and temperature conditions were investigated. The annual average rainfall of Yenice district (847 mm) is higher than that of Ezine (547 mm). Some physicochemical analyzes and mineralogical analyzes such as XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy), and EDS - EDX (Energy Dispersive X-ray Spectroscopy), and major oxides were performed was performed on soil samples taken on the basis of horizon in soil profiles with morphological definitions. Some weathering rates such as CIA (chemical weathering index), PIA (plagioclase alteration index) and SiO2/Al2O3 were calculated from the oxide analyses results. Profile 1 contains O-A -Bt-C-R and profile 2 contains A-Bw-C horizons. Profile 1 is sandy loam on the surface, clay loam and clay subsurface, and profile 2 is generally sandy clay loam. While an argillic horizon was formed in P1 as a result of leaching, there was a cambic horizon in P2. While the cation exchange capacity (CEC) in P1 was 42.48 cmolkg-1 in the argillic horizon, it was determined as 26.72 cmolkg-1 in the cambic horizon of P2. CIA and PIA dissociation indices of P1 were higher than that of P2. According to this result, it was determined that feldspars were more decomposed in P1 which had an older profile compared to P2. In addition, according to XRD analysis, kaolinite was present in P1 and albite was not found in feldspars, while kaolinite was not found in P2 and a significant amount of albite was determined. Soil profiles are classified as follows, respectively, according to soil taxonomy; profile 1 is Lithic Haplustalf, profile 2 is Humic Dystroxerepts; According to the WRB classification, profile 1 is classified as Epileptic Luvisols (Abruptic) and profile 2 is classified as Haplic Cambisols (Dystric).The results of the study showed that the differences in precipitation, which is one of the climate parameters, affect the profile structure of the soils, weathering levels, physico-chemical properties, and soil taxonomy in two soil profiles formed on andesitic rocks and under similar topographic conditions
