    Determination of Nutrient Contents and In vitro Gas Production Values of Some Legume Forages Grown in the Harran Plain Saline Soils
    (ASIAN-AUSTRALASIAN ASSOC ANIMAL PRODUCTION SOC, 2014) Boga, M.; Yurtseven, S.; Kilic, U.; Aydemir, S.; Polat, T.
    The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non salty electrical conductivity (EC)<4 dS/m; low salt: 4 dS/m>EC<8 dS/m, medium saline: 8 dS/m>EC<16 dS/m and high salt: 16 dS/m>EC) was used in the study. Results indicated that salinity and plants had no significant effect on ash and ether extract. Dry matter (DM), acid detergent fiber, digestible dry matter, dry matter intake (DMI) were affected by plant, salinity and plantxsalinity interaction. On the other hand neutral detergent fiber, relative feed value (RFV), and DMI were affected by salinity and plantxsalinity interaction. Mineral contents were affected by plant species, salinity and salinityxplants interactions. In vitro gas production, their kinetics and estimated parameters such as were not affected by salinity whereas the gas production up to 48 h, organic matter digestibility, metabolizable energy (ME), and net energy lactation (NEL) were affected by plant and plantxsalt interaction. Generally RFVs of all species ranged from 120 to 210 and were quite satisfactory in salty conditions. Current results show that the feed value of Medicago saliva is higher compared to Lotus corniculatus and Trifolium alexandrinum.

    The effects of different compounds in some essential oils on in vitro gas production
    (KIELANOWSKI INST ANIMAL PHYSIOLOGY NUTRITION, 2011) Kilic, U.; Boga, M.; Gorgulu, M.; Sahan, Z.
    The aim of this study was to determine the effect of essential oils (EO) of oregano, ORE (Origanum vulgare); black seed, BSD (Nigella sativa); laurel, LAU (Laurus nobilis); cumin, CUM (Cumminum cyminum); garlic, GAR (Allium sativum); anise, ANI (Pimpinella anisum), and cinnamon, CIN (Cinnamomum verum) on in vitro gas production (IVGP) and IVGP kinetics of barley, wheat straw and soyabean meal. IVGP values were determined by using rumen liquor from three dry Holstein cows. The findings of this study indicate that the effects of EO, doses, and EO x dose interactions were significant. IVGP was decreased by ANI, GAR and ORE, and only CUM increased IVGP. These EO and their different doses or combinations in diets could be used to improve the performance of ruminants. Moreover, EO may act at different levels in energy and protein metabolic pathways, thus their careful selection and combination may be a useful tool to effectively manipulate rumen fermentation.
