SUMMARY A dynamic flock model (DFM) of intensive Barki sheep production system in Matrouh Governorate is presented. The model studies the complexity of the reproduction management systems of three lambing in two years and the productive efficiency and financial return. The data for three production cycles were collected during 2006-2009 from a Barki flock of the Sustainable Development Center for Matrouh Resources, Desert Research Center, Ministry of Agriculture. The flock size was started by 367 yearling ewes, all joined for first time in September, 2006 with 30 fertile rams in matting groups. According to the first meeting result, the ewes divided into two batches. First batch including the pregnant ewes and other including non pregnant ewes. Productive traits studied were lambing %, weaning %, twining %, mortality % from birth to weaning%, number of ewe joined, number of ewe lambing, number of lambs born, number of lambs weaned and replacement rate of yearling ewes. Financial indicators considered for each production cycle were gross output of flock product (lambs sold, wool, manure and culling animals) and gross margin. Input/output data of both batch's productivity and financial were analyzed at each phase corresponded to the characterization of the each batch flock. The results showed that The overall average of lambing %, weaning %, twining % and mortality from birth to weaning% were 86%, 98%,5% and 9%, respectively. The differences of gross margin ranged between -32625 LE in first cycle to 21748 LE in third cycle. The gross output of lambs, wool, manure and culling animals in first production cycle was about 87%, 2%, 11% and 0%, respectively of the total gross output. While, in second production cycle was 71%, 2%, 9% and 18%, respectively and in third production cycle was 67%, 2%, 11% and 21%, respectively. It could be concluded that productive studied traits were better than investigated by other research paper, except that weaning %, which led to less sold lambs, which effected on financial return. Finally, could be investigated that intensification Barki sheep production system in Matrouh governorate was not satisfied income, because the gross margin contributed -23%, 8% and 12% for three studied production cycles, respectively.
