This study aimed to evaluate the effect of fiber content on feeding, growth performance, feed utilization and antioxidant ability of Taiwanese loach. The experimental feeds were divided into six groups, with crude fiber contents of 4.70%, 4.92%, 5.15%, 5.44%, 5.79% and 6.06%, respectively. A total of 576 loaches were randomly divided into 6 groups with 8 replicates of twelve fish each, and fed for 60 days. The results showed that crude fiber levels had significant effects on feeding rate (FR), feed conversion rate (FCR) and protein efficiency ratio (PER) in loaches, while specific growth rate (SGR) showed no significant difference (P>0.05). Crude fiber content had a significant effect on loach digestibility (P<0.05), first showing an increasing trend before dropping. There was no significant change in tryptase and lipase activities (P>0.05), while amylase activity decreased s.. View more»
