The need for roughage in the animal nutrition industry has led to the search for various alternative roughage. In this context, as a result of the research, tree leaves have the potential to be considered as a nutritious and balanced forage source for animals. In this study, it was aimed to investigate the usability of apple (Malus domestica), apricot (Prunus armeniaca), cherry (Prunus avium), grape (Vitis vinifera), and umber mulberry (Morus rubra) leaves in ruminant nutrition. As a result of the research, nutritional contents of tree leaves (dry matter, crude protein, crude ash, crude oil, neutral detergent fiber, acid detergent fiber, acid detergent lignin, tannin), in vitro gas, carbon dioxide and methane gas production, in vitro gas post-production rumen fluid volatile fatty acid contents were found to be different from each other (P<0.05). In addition, although metabolic energy, organic matter digestion, digestible dry matter, dry matter consumption and relative feed values were found to be different in tree leaves (P<0.05), the highest values of these parameters were found in mulberry leaves. Metabolic energy (ME-J/kgDM) in grape, mulberry, apple, apricot and cherry is 9.24, 10.69, 10.07, 10.24, 9.33, organic matter digestibility (OMD-%) is 56.49, 58.98, 54.46, 57.34, and 58.31, respectively. has been detected. In the volatile fatty acids in the rumen fluid of the leaves after in vitro gas production; Total volatile fatty acid (TVFA-mmol/L) was defined as 69.16, 76.25, 66.04, 68.63, and 65.24, acetic acid (AA-mmol/L) was determined as 44.90, 48.52, 41.93, 46.82, and 43.62, respectively. As a result of our detailed studies, it has been determined that the leaves of various fruit trees stand out with their considerable nutritional content. The most important reason for the differences in the findings is that the nutritional content of tree leaves is different from differs. As a result of our comprehensive study, these nutritional content differences offer significant potential for using leaves of various fruit trees as a source of forage.
