RESEARCHES REGARDING THE INDUSTRIAL CROSSING EFFECT BETWEEN DIFFERENT SHEEP BREEDS OVER THE GROWING INTENSITY AND THAT OF THE SLAUGHTER INDICATORS
The aim of the research was to explore new solutions to produce increased quantities of sheep meat. The opportunity to carry out these surveys is because Romania has a very good position among the countries with large herds of sheep and that the European Union level requirements for sheep meat are not fully insured. Biological material intended for fattening of lambs was represented by half breed sheep coming from the crossing of mixed F1 females (Bluefaced Leicester x Merinos de Palas and Tigaie) with Suffolk rams. In the statements made to avoid calculation errors induced by intestinal content slaughtered individuals were not fed with 12 hours prior to slaughter. The objective assessment of the carcasses was done by determining the following elements: chassis, yield to mass slaughter, the determination of the physical structure of the carcasses, carcass classification graded by quality according to the method applied in the European Union and cut the carcass portions depending on quality. After the assessments carried out on the bodies, they were cut into regions for slaughter then were boned to determine the bone/meat ratio, both for the carcasses and for each region cut. The results obtained confirm and justify the application of cross-breeding when the main activity is represented by meat production.
