    Chemical Composition and Nutritive Value of Oak (Quercus robur) Nut and Leaves
    (GARUDA SCIENTIFIC PUBLICATIONS, 2010) Kilic, Unal; Boga, Mustafa; Guven, Inan
    To determine the potential nutritive value of different parts of Quercus robur chemical composition and in vitro gas production technique were used. Crude protein, dry matter contents and gas production of kernel were higher (P<0.01) than the other parts of oak, whereas, CT, NDF and ADF contents were lower. The NDF and ADF contents of cup and hull were significantly higher compared to those of the other parts of oak. Oak nut and leaves have potential nutritive value for ruminant animals.

    Determination of potential nutritive value of cotton gin trash produced from different feed companies
    (TAYLOR & FRANCIS LTD, 2015) Ozkan, Cagri Ozgur; Boga, Mustafa; Atalay, Ali Ihsan; Guven, Inan; Kaya, Emrah
    The aim of this study was to determine the potential nutritive value of cotton gin trash obtained from five different companies using chemical composition and in vitro gas production technique. There was considerable variation among cotton gin trash obtained from five different companies in terms of chemical composition and in vitro gas production, metabolizable energy (ME) and organic matter digestibility (OMD). The crude protein (CP) contents of cotton gin trash ranged from 6.59% to 12.55% on dry matter (DM). Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents ranged from 49.24 to 62.22% on DM and 40.73 to 48.31% on DM respectively. The gas production ranged from 22.91 to 33.51 ml of 200 mg of DM after 24-h incubation. The ME and OMD contents of cotton gin trash ranged from 5.38 to 7.09 MJ/kg DM and 37.44 to 52.69% respectively. In conclusion, chemical characterization of CP, OMD and ME suggests that the cotton gin trash moderate level of CP concentration and was digestible therefore it could be said that cotton gin trash will provide roughage of an acceptable quality for ruminant animals.

    Effect of Varieties on Potential Nutritive Value of Pistachio Hulls
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2013) Boga, Mustafa; Guven, Inan; Atalay, Ali Ihsan; Kaya, Emrah
    The aim of this study was to determine the potential nutritive value of pistachio hulls obtained from six different varieties using chemical composition and in vitro gas production technique. In vitro gas productions of pistachio hulls were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times and their gas production kinetics were described. There is considerable variation among pistachio hulls obtained from six different varieties in terms of chemical composition and in vitro gas production, metabolisable energy (ME) and organic matter digestibility (OMD). Dry matter (DM) contents of pistachio hulls ranged 26.45 to 29.25%. Ash content of pistachio hulls ranged from 8.50 to 19.86%. The crude protein (CP) contents of pistachio hulls ranged 7.27 to 14.99%. The hulls from Kirmizi, Ohadi and Keten Gomlegi (KG) had significantly higher CP contents than the others. The NDF and ADF contents of pistachio hulls ranged from 18.25 to 22.49% and 14.32 to 18.29% respectively. The pistachio hulls from Ohadi and Uzun had significantly higher NDF and ADF contents than the others. The CT contents of pistachio hulls ranged from 2.03 to 2.63%. The hulls from Beyaz Ben (BB) had significantly higher CT content than that of KG. The gas production rate ranged from 0.071 to 0.107%. The gas production rate of pistachio hulls from Sultani and KG were significantly higher than the others. The potential gas production of pistachio hulls ranged from 65.92 to 73.46 mL. The potential gas production of pistachio hulls from BB and Ohadi were significantly higher than the others. The ME and OMD contents of pistachio hulls ranged from 9.76 to 11.05 MJ/kg DM and 69.00 to 74.50% respectively. The ME contents of pistachio hulls from BB and Ohadi were significantly higher than those of Kirmizi, Uzun and KG whereas the OMD contents of pistachio hulls from Ohadi were significantly higher than those of pistachio hulls for Kirmizi, Sultani, Uzun and KG. In conclusion, chemical characterization with CP, OMD and ME suggests that the pistachio hulls had moderate level of CP concentration and was quite digestible therefore it can be said that pistachio hulls will provide feedstuffs of an acceptable quality for ruminant animals.
