Determination of the In Vitro Gas Production and Potential Feed Value of Olive, Mulberry and Sour Orange Tree Leaves

This study was conducted to determine the potential nutritive value and gas production (IVGP) parameters of . (Olive = OL , . (Mulberry = ML) and . (Sour orange = SOL) tree leaves. Hohenheim gas test was used to determine the 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, gas productions, organic matter digestibility (OMD), metabolisable energy (ME), net energy lactation (NE ) and relative feed values (RFV) (P
