肉兔血浆AKP、GPT活性与生产性能关系的研究

对新西兰白兔、加利福尼亚兔、布列塔尼亚兔(A系)、齐卡兔(G系)、布列塔尼亚兔(A系,♂)×新西兰白兔(♀)、布列塔尼亚兔(A系)(♂)×加利福尼亚兔(♀)、齐卡兔(G系)(♂)×新西兰白兔(♀)、齐卡兔(G系)(♂)×加利福尼亚兔(♀)100日龄血浆碱性磷酸酶(AKP)、谷丙转氨酶(GPT)活性,及其与100日龄体重、平均日增重和料重比的相关性进行了研究。结果表明:齐卡兔(G系)、齐卡兔(G系)(♂)×新西兰白兔(♀)、布列塔尼亚兔(A系)血浆AKP活性显著高于新西兰白兔、加利福尼亚兔、布列塔尼亚兔(A系)(♂)×加利福尼亚兔(♀)(P<0.05)。加利福尼亚兔血浆GPT活性显著高于齐卡兔(G系)(♂)×加利福尼亚兔(♀),其它六个品种(或组合)兔之间差异不显著。八个品种(或组合)兔血浆AKP活性与100日龄体重、平均日增重均呈正相关,总相关系数均达极显著水平(P<0.01),与料重比呈负相关,相关不显著。八个品种(或组合)兔血浆GPT活性与100日龄体重、平均日增重基本上呈负相关,且总相关系数达显著或极显著水平,与料重比基本上呈正相关,总相关系数不显著。

STUDIES ON THE RELATIONSHIP BETWEEN ACTIVITIES OF PLASMA ENZYMES AND PRODUCTION PERFORMANCE IN MEAT RABBITS

The relationship between activities of plasma alkaline phosphatase(AKP)、glutamic-pyruvic transaminase(GPT)and production performance were studied in l00-day New Zealand,Californian,ZIKA(G),ELCO(A),ZIKA(G,♂)×New Zealand(♀),ZIKA(G,♂)×Californian(♀),ELCO(A,♂)×New Zealand(♀)、ELCO(A,♂)×Californian(♀)rabbits.The results showed that activities of plasma AKP in ZIKA(G)、ELCO(A)and ZIKA(G,♂)×New Zealand(♀)were significantly higher than that in New Zealand、Californian and ELCO(A,♂)×Californian(♀)(P<0.05).Activity of plasma GPT in Californian rabbits was significantly higher than that in ZIKA (G,♂)×Californian(♀),and there were no significant different between that in the others.There was significant positive correlation coefficient of total samples between activity of plasma AKP and l00-day weight (P<0.01).So was there between activity of plasma AKP and average daily gain.There was no significant negative correlation coefficient between activity of plasma AKP and ratio of feed to weight.There were basically negative correlations between acti vityof plasma GPT and l00-day weight 、average daily gain,and the total correlationcoefficients were significant or more significant (P<0.05or P<0.01).There was nobasically positive correlation between activity of plasma GPT and ratio of feed to weight,and the total correlation coefficient was no significant.
