|Abstract:||The effects of betaine supplementation on feed intake and growth performance in rainbow trout fed a plant-protein based diet were evaluated. Triplicate groups of rainbow trout (130 g) were fed the plant-protein basal diet, the basal diet with 1.5% betaine supplementation, or a fishmeal-based diet (control) for 80 days. Feed intake was significantly better (p<0.05) in fish fed the betaine-sup- plemented diet (161.2 g/fish) than in fish fed the basal diet (131.6 g/fish) and not significantly dif- ferent from fish fed the control (152.8 g/fish). Weight gain was significantly higher (p<0.05) in fish fed the betaine-supplemented diet (117.0%) than in fish fed the basal diet (95.9%). Results indi- cate that, in diets based on plant proteins that often have low palatability, betaine supplementation may improve feed acceptability and growth performance in rainbow trout.|
