To determine the chemical compositions, minerals and in vitro digestibility Legum straws during 1381 to 1383 years in shahrekord, kohrang and lordegan climates in Chaharmahal & Bakhtiari, samples took of legume species include: (lens calinorismedik Lentil, Lathyrus sativus L., Phaseolus Lunatus., Phaseolus colcaratus, phaseolus vulgaris var., cicer arietinum L., Vicia sativa and Vicia Feba). Which they were most dominant Legum straws that they used in ruminant winter diets in this province. These Legum straws gathering of different climates for three years (1381- 1383). All straws were chemically analyzed for DM, CP, CF, ASH, EE, NDF, ADF, ADL , Ca, P, Ma , K, Fe, Mg, Cu, Zn, and in-vitro digestibility include DMD , OMD and DOMD were determined in-vitro and energy was determined using of calorie meter bomb. All of the data classification with Excel software and used of SAS for statistical program. Total mean of CP for the above Legum straws was 7,52, 10,32, 7,57, 7,61, 8,01, 5,93, 7,21 and 8,72 percent respectively. Highest and lowest amount of CP were in Lathyrus sativus L. and cicer arietinum. Highest CF amount in pea straw with 31,89 percent and Lowest it was in was chiti bean with 27,41 percent. The results showed the highest and lowest amount of GE were 4007 kcal/ K DM and 3690,9 kcal/kg DM for lathyrus sativus and phaseolus lunatus respectively. The maximum NDF was due to pea straw with 48,6 percent and the minimum to chiti bean with 42,88 percent .A the maximum ADF was due to pea straw with 33,08 percent and the minimum to chiti bean straw with 29,80 percent. The mean of dry mater digestibility (DMD) for above Legum straws were 59,98, 59,8, 66,72, 65,9, 69,64, 53,52, 61,17 and 59,17 percent respectively, that was maximum in chiti bean straw and minimum in pea straw. The highest and lowest organic mater digestibility (OMD) was 67,38 and 49,82 percent which found in chiti bean straw and pea straw respectively. The minerals status showed that all of the Legum straws were above in Ca can provide for ruminant requirements. The mean of element was lowest in lens. Straw (0,14 percent) and highest in lathyrus (0,20 percent) and content of p was lower than critical value required for ruminant. The maximum Cu was 9,69 mg / kg DM in Vicia sativum and the minimum was 22,03 mg/kg DM. In addition to effect of climates and years were significant on nutrient, minerals and digestibility.
