WASTE AND BIOMASS VALORIZATION, 2024 (SCI-Expanded)
Effects of hosting trees on feed quality traits of mistletoe samples were investigated in this study. Mistletoe samples were collected from pine, willow, hawthorn, locust, apricot, wild pear and almond trees. Effects of hosting trees on nutritional traits of mistletoe leaves were found to be significant. The greatest crude protein content was observed in samples collected from locust tree and the greatest crude oil from pine tree, the greatest crude ash from apricot tree, the lowest ADF and NDF ratios from hawthorn tree. Condensed tannin contents of mistletoe samples varied between 0.68 and 0.97% and the differences in condensed tannin contents of mistletoe samples were not found to be significant. Apricot (53.85 ml) and wild pear (54.48 ml) had the greatest gas production and willow tree (10.61 ml) had the greatest methane production. Metabolizable energy (ME) values varied between 8.49 and 10.82 MJ (kg/DM) and organic matter digestibility (OMD) values varied between 58.26 and 73.97%. Although all samples were rich in minerals, pine tree was prominent for micro elements. The major saturated acids found in the leaf oils were palmitic acid and the major unsaturated fatty acids were oleic, linoleic and linolenic acids. The total saturated fatty acid levels of mistletoe collected from different trees were between 13.42 and 25.68%, while the total unsaturated fatty acids were between 74.32 and 86.58%. Mistletoe samples have amino acid content similar to forage crops. In addition, they have high value of proline. It was concluded based on present findings that mistletoe samples might constitute a quality feed source for animals. Use of parasitic mistletoe species in animal feeding may offer a well method in reduction of damages on forest and culture trees and supply a quality feed source for ruminants. [GRAPHICS]
