Abstract
In this study, effects of porcine growth hormone on the growth performance of rainbow trout (Oncorhychus mykiss) and its possible residue in fish meat[O1] and blood were investigated.[O2] The study was defined in two phases[O3] . The first phase is the rearing of the fish which were chosen to be in the same weight range as close as possible (90g-110g) [O4] till they reach the table size. [O5] Through this phase fish were injected with porcine somatotropin in periods differing from one group to another. First group received one injection, second two injections and third group received three[O6] injections. At the end of the study, fish in the experimental groups weighed more than the control groups. A1–K1 and A1–K2 groups were significantly different (p<0.05) in terms of weight, A2–K1, A2–K2, B1–K1, B1–K2, B2–K1, B2– K2, C1–K1 and C2–K2 groups were significantly different (p<0.01) as well[O7] . In the second phase, fish carcasses were analyzed for porcine growth hormone residues. There were no significant difference with the control groups in terms of residue levels.
