Abstract
Determination of grazing capacity depends on information about various factors such as forage quality and species nutrient values, and for achieve to ideal animal production information about nutrient value are very important. In this trial, nutrient values of twelve species were to evaluate, that were grazed by Mehraban sheep in two phenological stages (vegetative and maturity) in two sites of AghDagh & Galebor at Hamadan province. Forage quality indices as Crude protein (CP), acid detergent fiber (minus Hemicelluloses) (ADF),dry matter digestibility (DMD) and metabolisable energy (ME) were measured respectively. According to the results, significant differences were observed among the species and phonological stages for all measured and calculated forage quality factors (p<0.05). Generally, Information about forage quality factors is essential for animal nutrition management in rangeland and it should be considered in range and animal management designs.
