A concern for the growth and utilization of sheep is raised since ancient times in Romania. The development of livestock sector is determined by the climate and the geographical configuration with the availability of grasslands maintained by transhumants. The pastoralism founded a domestic processing of milk, wool and leather products with positive socio-economic implications on material and spiritual life of local people. The sheep breeds prevailed until the 20th century were ‘Tucana’ and ‘Stogose’ and, to a lesser extent, ‘Tisigai’. These breeds, generally unimproved, have a profound fitness and resistance to harsh weather conditions. These breeds were also fit for traveling long routes in search of food. The utilization of a sheep breed is determined by the national economic demand, productivity potential of the breed, available, technology, improvement and utilization methods of the breed. The said sheep breeds were appreciated because they produce a diversity of products having superior nutritional or economic values. It is known especially for its white wool, which is used in domestic industry for making clothes and other products including artifacts, textiles, Persian carpets, etc. Considering the local natural conditions and the national economic demands, the sheep husbandry was assisted continuously to support intensive and multilateral development producing the necessary raw materials for the textile, fur, leather and food industry. Both research and the technical developments have contributed to the zootechnical field geared to resolve the problems appeared in the development of sheep. The scientific knowledge and expertise need to be combined with application skills leading to the development and modernization of complex technologies helping growth of sheep products.

A rising of sheep flocks represents one of the economical procedure imposed to be solved every one year, in the generations’ succession, through a judicious organizing of a complex reproduction activity, of breeding, of exploiting, of improvement and economical analyzing. A consequence of unspecified disease of this specie is the morbidity and the losses, generated by the infringement breeding exploiting conditions, adding the parasitical diseases, especially these linked to the lawns. This work suggests to be a radiography of the actions connected to breeding and exploiting the sheep on family farm conditions. The scientific management of production process is supposed to know the results of the activiyies of the assembly factors, which influence in a positive or a negative way the economic efficiency level, regarding the irrational leading of all the actions made to obtain a maximum economic efficiency.

Nowadays, tigaie breed represents almost 26 percents of tha total sheep group in our country, being grown on the hill, plateau and depression areas, with atmosphero=ic precipitation of 650-800 mm, and in limited number in some submontane areas. The proportion of the Tigaie breed will be in the future of about 24% of the total herd. Due to its exceptional resistance and superior combining capabilities, the Tigaie breed will be a biological source of industrial cross-breeding and improvement, as well as the creation of new types, for fine-meat-milk wool, such as Spanca genetically stabilized or semifine-wool, as well as semi-wool milk. In order the breed to be properly harvested in the shown directions, it is necessary to keep valuable cores in the pure breed, subject to an appropriate selection and propagation program. The economic efficiency of animal production is largely determined by the results obtained by forage crops, the low cost of feed, contributing to the increase in the economic efficiency of livestock production.
