A 75‐day feeding trial was conducted to evaluate the nutritional implication of feeding diets containing graded levels of sundried cassava leaf meal (SCLM) to Labeo rohita fingerlings. Four isonitrogenous (300 g/kg crude protein) and isoenergetic (18 MJ/kg) diets were prepared by replacing de‐oiled rice bran (DORB) with 0 (diet 1), 130 (diet 2), 260 (diet 3) and 390 g/kg (diet 4) of SCLM. The diets were fed to the triplicate groups of L. rohita fingerlings (average weight, 2.03 ± 0.03 g) in a completely randomized experimental design. At the end of the trial, diet 3 had similar (p > 0.05) percentage weight gain (106.38 ± 4.41%), specific growth rate (1.29 ± 0.04%/day) and feed conversion ratio (2.38 ± 0.08) relative to the control group. Intestinal digestive enzyme activities, hepatic and muscle transaminases and proximate body composition of L. rohita fingerlings were not significantly (p > 0.05) influenced by the dietary treatment. Superoxide dismutase activity of the group reared on diets 3 and 4 was significantly (p < 0.05) higher than that of diet 1. Based on the second‐order polynomial regression analysis on the expression of IGF‐I and IGF‐BPI, it was concluded that as much as 166.5 g/kg DORB can be replaced by SCLM for optimal growth performance, in the diets of L. rohita fingerlings.

饲喂晒干的木薯叶粕作为罗胡，Labeo rohita，鱼种饮食中的脱油米糠的替代品：对igf-i和igf-bpi的生长，酶活性和基因表达的影响

进行了为期75天的喂养试验，以评估含分级木薯叶粉（SCLM）水平的饮食对Labeo rohita鱼种的营养影响。通过用0（饮食1），130（饮食2），260（饮食3）和390克/千克（饮食4）的SCLM。在完全随机的实验设计中，将日粮喂入三倍的罗氏乳杆菌鱼种（平均体重2.03±0.03 g）。在试验结束时，饮食3具有相似的（p > 0.05）相对于对照组的体重增加百分比（106.38±4.41％），比生长速率（1.29±0.04％/天）和饲料转化率（2.38±0.08）。 饮食处理对罗希塔鱼种鱼肠的消化酶活性，肝和肌肉转氨酶及附近身体组成没有显着影响（p > 0.05）。饮食3和4的组的超氧化物歧化酶活性显着 高于饮食1 （p <0.05）。根据对IGF-I和IGF-BPI表达的二阶多项式回归分析，得出结论即多达166.5克/ kg的DORB可以通过SCLM被替换以进行最佳生长的性能，在饮食L.鲮鱼种。
