This experiment was carried out at the Grdarash field belongs to the Agricultural researches directorate/general Agriculture directorate-Erbil in September (2007) E 27 Arabic lambs aged (5-6 months) With average initial weight (39.178 Kg / lamb) were used.

Lambs were divided in to (3) groups (9 lambs / group).

Control group was fed on (85% barely E 10% bran and 5% straw) E and second and third groups were fed on various by-product in replacement with barely in loss and block shape respectively.

The total gain of three groups were (392708.32E 634826.52 and 445613.72 ID respectively)E average simple returned (0.33E 0.47 and 0.38 respectively) E average fund return (3.06 E 2.139 and 2.66 times respectively) E total fund return period (183.6 E 128.34 and 159.6 days 238.52 & 250.52 days respectively) E forage productivity (26.89 E 31.74 and 29.74 respectively).

At sensitive estimating total gain for three groups were (336498.6E 488257.6 and 391816.6 ID respectively) E average fund return (0.317E 0.466 and 0.373 times respectively) E average fund return (3.153E 2.148 and 2.676 times respectively)E total fund return period (189.18E 128.88 and 160.56 days respectively) and forage productivity (17.07E 21.41 and 20.06 respectively) .It was found the lambs were fed on different by-product in loss or block type were more economical than lambs fed on barely and the effect of changing price representing by sensitive it's effect was less negative in lambs fed on different by-product in loss or block type than lambs in control group fed on barely only at estimating average fund return and total fund return period.
