DETERMINATION OF IN VITRO GAS PRODUCTION KINETICS AND CHEMICAL COMPOSITIONS OF LIGUSTRUM AND JASMINE TREE LEAVES

This study was carried out to determine the feed values and in vitro gas production (IVGp) kinetics of Ligustrum vulgare L. (Oleaceae) and Jasminum officinale L. tree leaves. In vitro (Hohenheim) gas test was used to determine the in vitro gas productions of the leaves for 3, 6, 9, 12, 24, 48, 72 and 96 h after incubation. General Linear Modal was used to compare gas production, and gas production kinetics of samples. The findings of the present study suggested that there were differences between the tree leaves in terms of crude protein, ash, ADF, in vitro gas productions, OMD, ME and NEL values (p<0.01). Ligustrum and jasmine leaves had similar condensed tannin and NDF contents (p>0.05), but ligustrum leaves showed more IVGp, organic matter digestibilities and energy values than jasmine leaves (p<0.01). In conclusion, it was determined that the leaves used in the study have low in vitro gas production and can be utilized as additives for alternative roughage feed in ruminant nutrition. However, it is recommended that the results obtained from this research should be combine with other forages and tested in in vivo studies.
