  • The Alanine Kinase activities in Heterobranchus bidorsalis juveniles (14.57 + 0.44g) fed with five graded concentrations (10.00, 20.00, 30.00. 40.00 and 50.00%) of dietary unprocessed soyabean meal (USBM) and a control (0.00% USBM) for 56 days were studied. Significant increases (P< 0.05; P< 0.01) in the serum alanine kinase (SAK) and hepatic cytosolic alanine kinase (HCAK) activities in the fish were dependent on the concentration of USBM in the diets. This result is consistent with the reports of other workers: especially on enzymatic responses to the infiltration of extraneous substances into the blood and liver tissues. Increases in SAK and HCAK activities between days 14 and 56 of the study imply that time affected the activities of alanine kinase both in the blood serum and in the liver tissues. It was apparent from the result that the USBM, not only exerted its anti-trypsin pressure on the ultimate protein digestion, absorption and turn-over in the fish as established by previous workers; but facilitated the activities of alanine kinase in its glycolytic phosphorylation potentials and consequent energy metabolism of the fish.
