Determination of Anti Methanogenic Characteristics of Some Tree Leaves Using In Vitro Gas Production Technique
Journal Title: Black Sea Journal of Agriculture - Year 2019, Vol 2, Issue 1
Abstract
The aim of the current experiment was to determine the antimethanogenic properties of some tree leaves containing condensed tannin. It has been found that there are significant differences among tree leaves of Styrax officinalis, Salix alba and Alnus glutinosa in terms of chemical composition. Crude ash contents of tree leaves ranged from %4.42 to 13.33 with highest being for Styrax officinalis. Ether extract contents of tree leaves ranged from %5.68 to 9.28 with highest being for Styrax officinalis and Salix alba. Crude protein contents of tree leaves ranged from %11.64 to 18.40 with highest being for Alnus glutinosa. Neutral detergent fiber and acid detergent fiber contents of tree leaves ranged from %28.95 to 50.21 and 22.73 to 33.09 respectively, with highest being for Salix alba. Condensed tannin contents of tree leaves ranged from %1.59 to 14.29 with highest being for Styrax officinalis. It has been found that there are significant differences among tree leaves in terms of gas, methane production, organic matter digestibility, metabolisable energy contents in the absence and presence of PEG. Supplementation of PEG improved all parameters measured in the gas production experiment. It can be said that the tree leaves studied in the current experiment has a low anti-methanogenic potential since the percentage of methane ranged from %11 to 14. It is required that these tree leaves should be tested with in vivo experiment to determine the anti-methanogenic potential of these tree leaves.
