  The results regarding influence of structure food on the main reproductive indexes in young sheep female of Tsigai breed, 12-13 months old are presented in this paper. The main reproductive indexes were calculated in time period October 2009-May 2010 for three groups of young female sheep. Groups were fed with different rations structures: string, semi-concentrated and semi-succulent. Results showed that the highest values of reproductive indices were recorded in group fed with ration of semi-succulent type.

  In last ten years, Romania occupies the first place within the European countries concerning the number of exploited sheep heads, destined to slaughtering. Over 97% of the volume of this export is represented by the Turcana young sheep, and difference of 3 % is represented by Tsigai young sheep. The determination of the chemical composition of the meat, the surface of Longissimus dorsi and leg of mutton area from Tsigai young sheep, Suffolk x Tsigai and German blackface x Tsigai intensive fattened is the aim of our paper. The determination of the chemical composition of the meat allows a deep analyze of its quality traits, making possible the evolutive characterization of the breed. The work methodology involved analyze of the chemical composition of the meat harvested from cutlet (Longissimus dorsi, LD), according to Weende pattern: water content, dry matter, crude protein, crude fat and crude ash. The results obtained show that the Tsigai young sheep has the highest water and lowest dry matter content, and German blackface x Tsigai, the lowest water and the higher dry matter content. The groups of cross breed achieved higher Longissimus dorsi (LD) and leg of moutton area, compared with the pure breed. Compared with Tsigai breed, Longissimus dorsi (LD) area determined was higher with 13.94% to Suffolk x Tsigai, and 2.14%, respectively to German Blackface x Tsigai. Leg of moutton area was higher with 24.09% to Suffolk x Tsigai, and 9.26%, respectively to German Blackface x Tsigai.

  Carcasses of Tsigai breed and Suffolk and German Blackface crossbred lambs fattened in an intensive system were subjectively (according with EUROP system) and objectively evaluated. After conformation, carcasses of Suffolk crossbred lambs were included in U and R, German Blackface x Tsigai in R, and carcasses from Tsigai pure breed in R and O classes. After the layer of fat, carcasses of Suffolk crossbred lambs were included in 2 and 3 classes, German Blackface x Tsigai in 3, and carcasses from Tsigai breed in 3 and 4 classes. Suffolk and German Blackface crossbred lambs had a higher (P<0.001) muscle proportion in all carcass parts than Tsigai breed lambs. Tsigai breed had a higher fat proportion than Suffolk and German Blackface crossbred lambs in almost all carcass pieces, but significant differences were founded in carcass rests (P<0.001). It was concluded that Suffolk and German Blackface rams could be used for crossing with Tsigai ewes to produce lambs with better carcass conformation and leaner carcass.
