JF - BIOTROPIA JA - BIOTROPIA VL - 0 IS - 24 SE - Research Paper DO - 10.11598/btb.2005.0.24.175 UR - https://journal.biotrop.org/index.php/biotropia/article/view/175 SP - AB - This experiment was conducted to study the effect of 3, 5, 3'-triiodothyroninc (Tj) hormone on nucleic acid and protein <br />content of the muscle and the growth of giant gouramy, Osphronemus gouramy  Lac. Five experimental diets, which contain <br />isocaloric diets, but different in T3 hormone level were used in this experiment (0.0, 2.5, 5.0, 7.5, and 10.0 mg T3 hormone/kg diet). <br />The experimental diets were tested to three different groups offish for sixty days feeding trial. Fish body weight in groups I, II, and <br />III were 0.39-0.42 g/fish; 19.11 -21.99 g/fish, and 37.52-40.79 g/fish, respectively. <br />The results showed that the highest RNA, DNA concentration and RNA/DNA ratio of the muscle were produced by 10.0 mg <br />T3 hormone/kg diet for group I and II; and 2.5 mg T3 hormone/kg diet for group III. Similar results also were found for the protein <br />content of the whole body, protein retention, and the daily growth rate of the fish. <br />Key words :   Osphronemus gouramy/Ti hormone/nucleic acid/protcin/growth ER -
