    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 the In Vitro Gas Production and Potential Feed Value of Olive, Mulberry and Sour Orange Tree Leaves
    (De Gruyter Poland Sp Z O O, 2018) Olfaz, Mustafa; Kilic, Unal; Boga, Mustafa; Abdi, Abdiwali Mohamoud
    This study was conducted to determine the potential nutritive value and in vitro gas production (IVGP) parameters of Olea europaea L. (Olive = OL), Morus alba L. (Mulberry = ML) and Citrus aurantium L. (Sour orange = SOL) tree leaves. Hohenheim gas test was used to determine the in vitro gas productions of the leaves. The gas production of samples over time was recorded for 3, 6, 9, 12, 24, 48, 72 and 96 h after incubation. Completely Randomized Design was used to compare gas production, and gas production kinetics of samples. The findings of the present study suggested that there were differences among the tree leaves in terms of crude protein, NDF, in vitro gas productions, organic matter digestibility (OMD), metabolisable energy (ME), net energy lactation (NE L ) and relative feed values (RFV) (P<0.01). ML had the highest condensed tannin contents (P<0.05), in vitro gas production (IVGP), OMD and energy values (P<0.01). SOL had highest RFV values. OL showed the lowest IVGP when compared to SOL and ML. Low NDF and ADF contents of SOL would probably increase the voluntary intake, digestibility and relative feed values of these leaves by ruminants. In conclusion, it was determined that OL, ML and SOL used in the study have low in vitro gas production and can be utilized as alternative roughage feed in ruminants. However, it is recommended that the results obtained from this research should be tested in in vivo studies.

    Effects of Feeding Regime Without Roughage on Performances and Rumen Development of Calves During Preweaning Period
    (ANKARA UNIV, FAC AGR, 2010) Goncu, Serap; Boga, Mustafa; Kilic, Unal; Gorgulu, Murat; Doran, Figen
    The objective of the study was to investigate the effect of only concentrate diet on growth and rumen development of Holstein calves during preweaning period. Thirty female and nine male calves were allocated to three treatments. Nine male calves were also divided into three treatments to operate for rumen wall samples. First group was fed with a calf starter and alfalfa hay as free choice, second group was received calf starter only and third group were fed with a total mixed ration (TMR) during the pre-weaning period. The average daily gain of the free choice, calf starter only and total mixed ration groups were 528.39 +/- 29.82, 509.00 +/- 34.08 and 479.21 +/- 25.86 g respectively. The average daily feed intake of the groups were 672.75 +/- 69.86, 619.73 +/- 77.75 and 499.60 +/- 81.69 g respectively. Calf starter group showed similar performances to free choice and TMR group of calves (P > 0.05). Protozoa number were not significantly different among the treatments while total bacteria numbers were higher for calf starter group than the other two groups (P < 0.05). The calves received calf starter only had flatter and more branched papillae than did the other calves. These results revealed that it is possible to rear calf successfully without roughage during preweaning period.
