In order to investigate management of traditional, industrial and semi industrial sheepfeedlot units in seven state of IranKhorasan, Fars, Yazd, Hamedan, Markazi, Kerman shah, and Kurdistan studied. To estimate their production function (PF) and efficiency (E), 1144 active units were studied by completing questionnaires. The 194 active units were studied by direct control from 2002 to 2005. In each unit dietary and body weight changes of selected lambs and chemical compositions of feedstuff were measured. After data setting, descriptive parameters of quantitative and qualitative traits were computed. To compare means, non parametric tests (Chi-square and Kolmogorov– Smirnov tests) and parametric tests (paired–samples and independent– samples T tests) were used. Production function was estimated by using Cobb–Douglas model and efficiency was calculated by using deterministic production frontier and COLS method. In this survey meat production was affected by herd size, feeding and labor inputs. Fars province had 3,3% (lowest) and Kordestan had 47,7% (highest) percentage of industrial units. Ninety-six percent of feedlot units in the reviewed provinces were individually possession. The graduating position of feedlots managers were 28% unlettered, 22,8% having reading and writing ability, 9,9% diploma and less than 2% graduated in all provinces. Age average of most feedlots managers was 50 ± 0,38 years. Herd size and feeding inputs were used about pleasure boundary contrary to labor that was used more than pleasure boundary. Constant returns to scale was observed in feedlot units. Only 5,9 percent of traditional units showed more than 90% technical efficiency. Most of traditional units (73,5%) had above 70% of technical efficiency. Just 13,8% of industrial and semi-industrial units had more than 90% technical efficiency. Nearly 69% of these units showed above 70% of technical efficiency. The problems of active unit owners' in order of priority were: in adequacy of cash (%43), unit deficiency (%11), feedstuff inflation (%11), disproportionate of cast with income (%17), inadequacy of security, hygienic problems of housing, fluctuation of prices, lamb and feedstuff providing. The results showed less that %20 of initiated sheep fattening capacity in industrial and semi-industrial units were active, because of owner's inadequacy of cash, inadequacy of governmental support policies and non existence of economical profit.
