This study evaluated the effects of potato, wheat, rice, and corn starch on growth performance, blood parameters, digestive enzyme activity, antioxidative response, and gut microbiota of African catfish, . A control diet (a commercial fish diet) and four different starch (potato, PO; wheat, WH; corn, CO; rice, RC) formulations were fed to African catfish with average weight of 10.5g (n = 30) for eight weeks. The experiment was conducted in triplicates. At the end of the feeding trial, the growth performance of African catfish fed with potato starch (PO) was significantly higher than other treatment groups. Furthermore, this group recorded significant and lowest feed conversion ratio (FCR) compared to other groups. Meanwhile, there were no significant differences in all tested hematological parameters and antioxidative response between the groups. Digestive enzyme activities in the fish intestines, including amylase, lipase, and protease, were significantly higher in African catfish fed with the PO diet. In addition, this group demonstrated substantially lower viscerosomatic index (VSI) and hepatosomatic index (HSI) than other groups, indicating that the fish has more meat on its body. The PO diet group also recorded significantly higher a good gut microbiota. Therefore, the PO diet potentially improves African catfish's growth performance and health status.
本研究评估了马铃薯、小麦、大米和玉米淀粉对非洲鲶鱼生长性能、血液参数、消化酶活性、抗氧化反应和肠道微生物群的影响。将对照饲料（一种商业鱼类饲料）和四种不同的淀粉（马铃薯，PO；小麦，WH；玉米，CO；大米，RC）配方投喂给平均体重为10.5克的非洲鲶鱼（n = 30），为期八周。实验重复进行三次。在饲养试验结束时，投喂马铃薯淀粉（PO）的非洲鲶鱼的生长性能显著高于其他处理组。此外，与其他组相比，该组的饲料转化率（FCR）显著最低且为最低。同时，各组之间所有测试的血液学参数和抗氧化反应均无显著差异。在投喂PO饲料的非洲鲶鱼中，鱼肠道中的消化酶活性，包括淀粉酶、脂肪酶和蛋白酶，显著更高。此外，该组的脏体比（VSI）和肝体比（HSI）明显低于其他组，表明鱼体上的肉更多。PO饲料组的肠道微生物群也显著更高。因此，PO饲料有可能改善非洲鲶鱼的生长性能和健康状况。
