Comparison of the chemical composition of the leaves of eight trees and shrubs for livestock feeding (case study: livestock places around Javaherdeh Ramsar village)

This study investigates the effective factors in land-holders use of 4 tree species including: Acer velutinum, Quercus castaneifolia, Carpinus betulus, Diospyrus lotus and 4 species of shrubs including Mespilus germanica, Prunus cerasifera , Celtis australis and ALbizia julibrissin to feed livestock and determine their nutritional value in livestock places of forest regions around Javaherdeh village in Ramsar city of Mazandaran province at the end of leaf growth stage. In order to perform sampling in a stage vegetative growth was done randomly. Then the green leaves which were dried in the open air and sized were transferred to the laboratory. The aim was to determine forage quality including: parameters of crude protein (CP), phosphorus (P), nitrogen (N), potassium (K), insoluble fibers in acidic detergent (ADF), insoluble fibers in neutral detergent (NDF), Dry matter content (DMD), metabolic energy (ME). This research was conducted in a completely randomized design and the analysis of laboratory data in SPSS software and the analysis of information obtained from the questionnaire using Friedman test was used to perform statistical analysis of collected data. The results showed that the Albizia julibrissin species due to the amount of metabolic energy (11.25), dry matter digestibility (77.97), crude protein (22.77), crude fat (5.26), insoluble fibers in neutral detergent (52.44), have a higher forage quality than the other seven species. The findings indicate that the nutritional value of Albizia julibissin has been associated with its greater utilization by ranchers, it shows the importance of local knowledge in this field.
