The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg feed. There was an increasing linear effect of turmeric on the thickness of the muscular layer, and height and width of the folds of the intestine. In the liver, a quadratic effect was observed of turmeric on the percentage of hepatocyte cytoplasm and a decreasing linear effect on the percentage of sinusoid capillaries. A quadratic effect was also observed of turmeric on the liver glycogen. There was no effect of turmeric on the antioxidant activity in the liver, carcass composition or productive performance of the fish. Thus, we concluded that Curcuma longa has trophic effects on the epithelium and the muscular layer of the intestine of A. aff. bimaculatus. Additionally, low levels of Curcuma longa cause increased deposition of liver glycogen and high levels cause reduction.
本研究的目的是评估姜黄（Curcuma longa）作为饲料添加剂对近似双斑丽脂鲤（Astyanax aff. bimaculatus）的影响。将体重为（0.83 ± 0.04克）的鱼投喂含0.0、20.0、40.0、60.0、80.0和100.0克姜黄/千克饲料的六种饲料，为期60天。姜黄对肌肉层厚度以及肠道褶皱的高度和宽度具有线性增加效应。在肝脏中，观察到姜黄对肝细胞细胞质百分比有二次效应，对窦状毛细血管百分比有线性降低效应。姜黄对肝脏糖原也有二次效应。姜黄对肝脏抗氧化活性、鱼体组成或生产性能没有影响。因此，我们得出结论，姜黄对近似双斑丽脂鲤的肠道上皮和肌肉层具有营养作用。此外，低水平的姜黄会导致肝脏糖原沉积增加，而高水平则会导致减少。
