Investigation of Potential Nutritive Values of Some Tree Leaves and Its Extracts by Using In Vitro Gas Production

This study was performed to assess the nutritional value of specific tree species (laurus nobilis, albizia julibrissin, glycyrrhiza glabra, salix alba, robinia pseudoacacia, liquidambar orientalis, juniperus communis, quercus coccifera, cedrus libani, arbutus andrachne) growing in different regions Kahramanmaras, besides gas production leaves and their extracts at various dose levels (0.6, 1.2 1.8 mL). The ADF NDF contents were differed between 16.20% - 32.47% 28%-49.66%, respectively. Liquidambar orientalis had highest values for both characteristics, whereas Salix alba lowest values. CP value, varied 7.94% 25.94%. concentration condensed tannins, 16.19%, Albizia julibrissin concentration, 2.12%. ME OMD ranged from 6.72 10.24 MJ kg-1 43.68 65.72%, GP content samples 22.25-40.03 mL 200-1 mg(DM). According study's dose, CH4 significantly increased when compared control group. leaf group 44.89 mL, doses at, 0.6, 1.2, found; 51.05-105.96 52.71-106.26 47.33-106.85 correspondingly. Methane (%) 16.54%, observed 16.64%-34.40%, 22.44%-34.80% 18.41%-31.46% Significant relationships production, ADF, have been found.
