The purpose of this study was to evaluate the effects of nonstarch polysaccharide (NSP) hydrolase (primarily xylanase and β‐glucanase), present in plant protein‐based diets, on growth, nutrient digestibility, and protease/amylase activity of Yellow River carp, Cyprinus carpio var.. Six hundred fish were randomly allocated to four groups in five replicates and fed diets with different NSP enzyme levels (0, 0.025, 0.05, and 0.1%) for 56 days. The addition of 0.05 and 0.1% NSP enzymes to diets significantly improved the specific growth and protein efficiency rates and reduced the feed intake and feed conversion rates (p
