Research of this paper are designed to provide important information on some indicators of quality of carcasses from young sheep of Tsigai breed and half-breed obtained by crossing between the local Tsigai breed with rams of specialized breeds for meat production Suffolk and German blackface. To this pourpose, three experimental lots of the specified breeds structures were formed, which were intensively fattened for a period of 100 days. At the end of the fattening process, were chosen five heads from each lot in a randomized and slaughtered. The methods used in the determinations were standard, and statistical data processing and interpretation was based on student test. Research results have shown that lots of half-breeds achieved higher slaughter yield, compared with the pure breed batch. Compared with Tsigai breed, slaughter yield determined to hot, cold and commercial was higher with 2,43, 2,71 and 2,65 points percentage, respectively to Suffolk x Tsigai half-breeds and 1,92, 2,03 and 1,96 percentage points, respectively to German blackface x Tsigai half-breeds. Researchs provide important information on efficiency of fattening the hybrids lambs for meat production obtained from crosses between Tsigai breed, and meat specialised breed, in terms under EU standards recovery.
