Dietary fishmeal versus soyabean meal: an assessment of serum and liver enzyme response in the chicken.
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.
