| 摘 要： | 用八眉猪、关中黑猪及其与杜洛克、长白猪的杂种共64头去势猪,分析其宰前血清中LDH,CPK,AKP,GPT和GOT活性与8个肉量性状及肉质性状的表型相关。结果表明,LDH,CPK,GPT活性与平均日增重、眼肌面积和瘦肉率的正相关较强,分别为0.2154,0.1599及0.3298(p<0.05);0.0976,0.1337及0.2512;0.3647(P<0.05),0.6293(P<0.01)及 0.6596(P<0.01);而与肥育天数、饲料转化率和脂肪率的负相关较强,分别是-0.3798(P<0.01),-0.1599及-0.2518;-0.1920,-0.0819及-0.2177;-0.3492(P<0.05),-0.1126及-0.4775(P<0.01)。AKP活性与平均日增重和眼肌面积的相关分别为-0.2317和-0.3295,而与胴体成份的相关较小。这些酶活性与肉质性状多呈负相关,其中以CPK,GPT和GOT与肌肉pH和总色素的相关较强(P<0.01)。分别为-0.4592和-0.5823,-0.3808和-0.4581,-0.5123和-0.4064。

| Abstract: | 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 (P<0.05); 0.0976, 0.1337 and 0.2512; 0.3647 (P<0.05), 0.6293 (P<0.01) and 0.6596 (P<0.01) respectively; and also negatively related to fattening days , feed conbcrsion rate and fat percentage in carcass, and they were -0.3798(P<0.01),-0.1599 and -0.2518; -0.1920.-0.0819 and -0.2177; -0.3492 (P<0.05),-0.1126 and -0.4775 (P<0.01) 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 (P<0.01) and they were -0.4592 and -0.5823,-0.3808 and -0.4581,-0.5123 and -0.4064 respectively. |
