To comidering of herdsmen unu to have llock. The lasl winler and carly spring with feeding shortage were mc~. and pay attenlion by the gr,1zing slalislil: of more 3.5 on the same kvd of range land production and for the purposing to supply partly of animal rorage requriment and the su!"\\'ey or livestock grazing on grain yield and suitable number was implimenlcd. Therefore. 65 male lambs with avcrage ages ISO:!: 15 days and the average live weight 30:t 1.2 kg were sekc.:ted. The c.:ompcktly randomized block dcsign(CRBD) was chosen as the stalistil:al th::sign of the Experiments with 4 treatment amI 3 repliL:,\\tion wcre used. 65 lambs w(.;rc divided into three groups 4, Sand 12 lambs. Four trealment consist of 4. S. 12 lambs ami cantor! trealment (no grilling). The goal or this expriment was using wheat green forage to sludy the grazing elTcCls un grain yield. each cxprimcnlal plots divided by means of faneing each others. For cach lams were rl:d with 250 gr wheat straw and ISO gr barely sllch as supplement...l fecLiing. Thc grazing priml was 15 days that animals red ad-libitum from wheat green ['oragc during 4-0 hOllrs in mid-day. Time of animal entranee to plot was selected at this lime 12 l em plant hight and 4 leaves stage and time of animal Exparture green forage 17 em plant hight too. The mount of green forage was measured. The measured factors were consist uf ear number in squre meter.grain number in car, ear lenght. plant hicght, the one thousand of grain, grain yield straw yieJd and Biological yield. All of the lambs were weighted at the beginning of trial and the end of trial. The results of Exprimcnl animal phase imlicate that average daily grain betwcen groups was significant. (PO.OI). A:i well as 4 animal treatment with 162 gr grain were higher than other groups this mount of S and 12 animal treatment 145 gr and 125 gr ADG were respectively. The average gain during grazing priod were for each animal such as 2.430 kg. 2. 177 kg and 1/863 kg as follow as 4.8 and 12 animal treatment respectively. The grazing dIect on grain yield. struw yield and Biulogical yidd were significant (p 0. 01). Grain vield were no significant Jirrcrence between contort with S91.5G kg/plot and four animal treatment with 854.07 kg/plot (each plot
