    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.

    EMISSIONS OF SOME GREENHOUSE GASES FROM THE MANURE OF EWES FED ON POMEGRANATE PEEL, YUCCA EXTRACT, AND THYME OIL
    (Corvinus Univ Budapest, 2018) Yurtseven, S.; Avci, M.; Cetin, M.; Ozturk, I; Boga, M.
    Sixteen dairy ewes 1 to 2 months pregnant and weighing 50.4 +/- 1.02 kg on average were randomly assigned to one of the four treatments, four animals to each treatment: 1) control, 2) yucca saponin (YE, 0.1%), 3) pomegranate peel (PP, 15%), or 4) thyme oil (TO, 0.1%). Total gas production from the fresh manure was measured and the contents of CH4, N2O, and CO2 were determined. Digestibility in vivo and nitrogen balance were also determined. Feed intake and body weight were not affected whereas some properties of the manure (dry matter, total N, ADF, and NDF but neither ash nor pH) were affected by the composition of the feed. Total manure production and the emissions of CH4 and CO2 expressed as parts per million per millilitre of manure were similar in all the four treatments whereas the content of N2O was higher in the control. Supplementing the rations with tannin, saponin, or thyme oil reduced N2O emissions from the manure.
