In order to increase the data pool of feed resources and complete the Iranian tables,90 villages were selected by stratified randomized sampling method. Pea straw and sunflower(stem and plate) were sampled from 90 selected village and 30 final samples were prepared for each feed . All samples were chemically analyzed and digestibility was determined in vitro and in vivo . The average DM,CP,EE,CF,NDF,ADF ,Ca and P were 95.05 ± 0.44, 4.54±0.87,0.65±0.1,38±2.14,47.3±3.1 , 38.67±3.1, 2.88±0.39 and 0.29±0.04 for pea straw95.03±.38 , 3.99±0.96 , 1.01±0.5, 43.84±4.48, 57.03 ±4.37 ,44.89±4.28 , 2.25±0.48 and 0.23±0.04 for sunflower stem and 94.97±0.34 7.78±1.41, 2.83±0.49 , 17.47±2.14, 23.3±3.22 , 17.75±2.49 , 2.45±0.27and 0.25±0.02 percent for sunflower plate respectively. The average in vivo digestibility of DM, OM ,CP ,CF and NFE were 43.52 47.87 , 52.48 , 50.84 and 42.92 percent for pea straw , 48.87, 50.33 , 48.32 , 36.27 and 51.08 percent for sunflower stem and 49.65 , 55.75 , 52.92 , 47.77 and 49.47 percent for sunflower plate respectively. In vitro digestibility of DM, OM were 51.48 ± 2.7 and 53.85 ±4.4 , 43 ± 3.5 , 46.06 ± 3.4 , 49.4 ± 2.9 and 59.4 ± 3.4 percent for above fed stuff respectively. No significantly differences were observed between the in vivo and in vitro methods for DM and OM digestibility of the feedstuff.
