In a five-week feeding trial, 90 broiler chicks were used to study the response of serum and liver alanine aminotransferase (ALT) aspartate aminotransferase (AST), sorbitol dehydrogenase (SDH) and alkaline phosphatase following the replacement of varying levels (0, 20, 40, 60, 80 and 100 per cent) of fishmeal protein by soyabean meal protein. The results showed that both serum ALT and AST activities increased significantly (P less than 0.01) with the increasing levels of substitution of soyabean meal for fishmeal. Regression analysis showed a significant (P less than 0.01) positive correlation between ALT and AST activities and the level of soyabean meal substitution with correlation coefficient, r, of 0.93 and 0.98, respectively. The liver ALT and AST tended to increase with the increasing proportion of soyabean meal although such increases were not significant (P greater than 0.01). Serum and liver SDH and alkaline phosphatase activities were not significantly influenced by diet.
在一项为期五周的饲养试验中，选用90只肉鸡雏鸡，研究用豆粕蛋白替代不同水平（0%、20%、40%、60%、80%和100%）鱼粉蛋白后，血清和肝脏中丙氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST）、山梨醇脱氢酶（SDH）和碱性磷酸酶的反应。结果表明，随着豆粕替代鱼粉水平的增加，血清ALT和AST活性均显著升高（P<0.01）。回归分析显示，ALT和AST活性与豆粕替代水平之间存在显著的正相关（P<0.01），相关系数r分别为0.93和0.98。肝脏ALT和AST虽有随豆粕比例增加而升高的趋势，但这种升高并不显著（P>0.01）。日粮对血清和肝脏SDH及碱性磷酸酶活性无显著影响。
