The improvement of sheep production systems in the Fahs region necessitates a diagnosis of the current situation and a thorough analysis of management practices. To meet these objectives, 110 farms having the Barbarine meat breed from the region were surveyed. The analysis of gathered data revealed that the region is characterized by familial farming (91.8% of farms are small sized: 0 to 24.7 acres) held by middle age farmers (45.5% were 35 to 55 years old) of which 80% are illiterate or at most have attended primary school). The total sample size of animal was 2059. Animals were lodged in traditional and are mostly fed on pasture and by-products, and supplemented occasionally by concentrate during critical physiological stages. The overall management of the Barbarine breed seemed unsatisfactory with indicators below common accepted performances. In fact, 80% of farmers practice shearing on pregnant ewes, a long breeding period without the ram effect, and do not respect the sex- ratio. The lambing period was then unnecessary long (July-December) with a peak in October (53.6%). The analysis of reproduction performances showed that farms may be classified into two categories: The first class of 19% of herds had 90%, 9.23% and 14.4% rates for fertility, sterility and abortion, respectively; and the second class with 113, 108 and 9.23 for prolificacy, fecundity and young mortality, respectively. Net income varied from 18.4 TD to 126 DT/ewe indicating important differences in management practices among farmers.
