Tomato pulp is the by-product of tomato juice manufactures and contains hulls and seeds. Tomato pulp contains 18.6 % dry matter(DM) and itJs nutrient composition includes 14.21% crude protein(CP), 8.26% ether extract(EE), 30.22% crude fiber(CF), 4.45% ASH and 0.45% phosphorous(P), respectively. The gross energy(GE) of tomato pulp was estimated 5233 Kcal/Kg.In This study 60 male lambs. of ATABAY breed was used. ALL of the lambs were similar in weightJ age and breed. A completely randomised design(c.RD) with 4 diets AJB,C and D(contain 0,10,20 and 30 % dried tomato pulpJ respectively).Lambs were fed 96 days.Average daily dry matter intake(DMI) and feed conversion ratios for were A,B,C and D 2.02,2.01,1.95 ,1.93 Kg/day and 8.76 ,8.54,8.26 J8.71, respectively. Final weight and average daily gain of lambs were 63.5,62.21 ,61.14,58.79 Kg and 231.75 ,235.07,216.7 and 198.1 g/daYJ respectively. There was significant difference among the final weight of lambs(p0.05)At the end of the experiment 5 lambs from each treatment were slaughtered and carcass characteristics were measured. There was significant difference between carcass J femur and fat weight (P0.05). The results of this experiment indicated that the costs of B ,C and D diets were 6.96J 17.1 and 27.2 percent lower than A diet. Cost of each kilo gram weight gain in B , C and D treatments(12.3J 16.8 and 21.6%J respectively)was cheaper than A too. Therefore ,the use of dry tomato pulp in fattening lambs diets to 30% level reduced the cost of feed intake and meat production.
