This study was conducted to determine the nutritive value of range plants in Baft area located in Kerman province(eastern Iran). Twenty seven species were sampled in 3 phonological stages (Flowering ,Seedling and Late seedling) from 133 rural location. The plants were: Artemisia aucheri , Artemisia persica , Scorzonera tortuosissima , Cousinia sicigera , Poa sinaica , Ajuga chamaecistis , Ziziphora clinopodioides , Amygdalus lycioides , Amygdalus elaeagnifolia , Daphne mucronata , Daphne stapfi , Ephedra intermedia , Efedra pachyclada , spachianus , Astargalus squarosus , Heliantemum lippii , Gymnocarpus decander , Zygophyllum atriplicioides , Fagoina indica , Hammada salicornica , Krascheninnikovia ceratoides , Ochardenus aucheri , Clypeola aspera , Allyssum linofolium , Ferulago ungulate , Semenovia suffruticosa and Dorema aucheri. All samples were prepared and chemically analyzed . The digestibility was measured using of In vitro in flowering, Seedling and late seedling stages were taken samples. The results of study technical method. Result showed that : The highest CP (16. 77%) was found in flowering stage of Ajuga chamaecistis , EE (6. 77%) in late seedeling stage of Dorema aucheri, Ash (30. 05%) in late seedeling stage of Zygophyllum atriplicioides, ADF (54. 4%) in late seedeling stage of Astragalus squarrosus , NDF (73. 0%) in late seedeling stage of Poa sinaica and DDM (82. 95%) in flowering stage of Fagoina indica. The lowest and highest percentage of Ca, P, Mg, K and Na were respectively 0. 33-8. 86 , 0. 008-0. 209 , 0. 052-0. 85 , 0. 35-1. 87 and 0. 05-0. 35 , Fe, Cu, Mn and Zn orderly were 65-1283 , 2. 03 - 14. 15 , 22. 7 - 174 and 6 - 67 mg/kg. As the plants matured concentration of CP, DDM, DE, ME and TDN decreased but ADF and NDF increased. There was a negative correlation between CP with ADF and NDF, DDM with ADF whereas a positive correlation was observed between CP and DDM. It can be concluded that the dominant forages contained CP, Energy and Ca enough for the extensive system grazing small ruminant in the area, but it's necessary to use P supplements to their diets. Also range plants had the highest quality in the vegetable stage.
