Determination of Quality of 33 species forage in Lar aera (Case study: Lar area, part ΙΙΙ in Down Elarm)

Information on forage quality and changes in pasture is one fundamental case in determination amount of forage daily requirements of animal unit to calculate grazing capacity of rangeland. Therefor, in this study 33 species of usable by the animal in vegetative and flowering stages were collected from the pasture in part one of down Elarm from Lar area. Percent of ADF and CP of samples was determined in the laboratory. Using the results obtained and the proposed equation Agriculture Standards Committee of Australia, percent of DMD and energy levels were determined according to MJ per Kg, for dry forage of pasture. So, the average percentage of CP in part one for 33 species in the vegetative stage is 19.95%, in the flowering stage is 14.4%. Average percentage of ADF for 33 species in the vegetative stage is 27.91%, in the flowering stage is 25.05%. The amount of DMD for 33 species in the vegetative stage is 52.24%, in the flowering stage is 48.62%. Also, Average values of metabolizable energy according to MJ per Kg in vegetative stage is 6.87 MJ, in flowering stage is 6.26 MJ.
