ABSTRACT
In the produced and consumed meat balance a part of pork is increasing in last years in the world. Increasing pork production, the demands for meat quality are increasing too. If it is known a genetic potential of separate breeds pigs of meat production it is searching most favorable crossbreeding combinations. In Lithuania the main breed of pigs is Lithuania white and beside this intensive selection import breeds pigs are breeding too. The purpose of this work is to make comparison estimation of meat characteristics and meat quality of Lithuanian White (LW) Germany Landrace (GL), Sweden Yorkshire (SY), English Large White (ELW) and German Large White (GLW). The tests showed that pigs of intensive selection has reached 100 kg mass 5-15 days faster than LW pigs (p<0.01). GL pigs growed most quickly. Their increase weight during a day was 115 bigger than LW pigs (p<0.05). SY breeds pigs had a bigger increase weight too (p<0.05-<0.01). The length of carcasses sides of other breeds pigs has separated too (p<0.05-0.001). Comporting with others breeds, muscularity of LW pigs was 0.71-2.21 % smaller (p<0.001->0.005). There are indicated statistical reliability of meat chemical compositions, pH, color, L*, a*, b*, drip loss, cooking loss, water holding capacity of tested breeds (p<0.001-p<0.05). It is made conclusion that it is best to cross Lithuania white pigs with Germany Landrace and Sweden Yorkshire.
