Yang Gongshc Lu Xingzhong Liu Xiaochun Guo Zhijun .( Department of Animal Husbandry. (Northwestern Institute of Light Industry)Northwestern Agricultural University)  
The phcnotypic correlation between the activity of scrum LDH.CPK, AKP, GPT and GOT and 8 meat performances was determined by using 64 castrated pigs of Bamci .Guanzhong Black and their crossbred with Duroc and Landracc. The results showed that the activity of LDH, CPK and GPT was positively related to average daily gain ,cyc muscle area and lean meat percentage in carcass, and they were, 0.215 4, 0.1599 and 0.3298 (P0.05); 0.0976, 0.1337 and 0.2512; 0.3647 (P0.05), 0.6293 (P0.01) and 0.6596 (P0.01) respectively; and also negatively related to fattening days , feed conbcrsion rate and fat percentage in carcass, and they were -0.3798(P0.01),-0.1599 and -0.2518; -0.1920.-0.0819 and -0.2177; -0.3492 (P0.05),-0.1126 and -0.4775 (P0.01) respectively. The activity of AKP was negatively related to average daily gain and eye muscle area, and they were -0.2317 and -0.3295 respectively. The activity of 5 enzymes was negatively related to meat quality traits. Especially ,thc activity of CPK,GPT and GOT were siginficantly related to meat pH and total pigment (P0.01) and they were -0.4592 and -0.5823,-0.3808 and -0.4581,-0.5123 and -0.4064 respectively.
