摘  要：
选择健康的吉富罗非鱼(体重1.29±0.25g)为实验鱼,配制五种木薯粉含量分别为0%、10%2、0%、30%和40%的等氮(粗蛋白为32%)、等能(总能为16kJ.g-1)实验饲料,饲喂罗非鱼56d,每饲料组设三个重复,研究不同含量木薯粉对吉富罗非鱼生长、饲料利用及全鱼营养成分的影响。结果表明:(1)木薯粉能提高罗非鱼的增重和蛋白质效率,其中以40%木薯粉组的效果最佳,其增重率、蛋白质效率和饲料系数分别为1470.99%(P<0.05)、2.36(P<0.05)和1.27(P<0.05)。(2)40%木薯粉组的干物质和蛋白质的表观消化率分别较对照组提高13.87%(P<0.05)和7.93%(P<0.05)。(3)40%木薯粉组的全鱼粗蛋白、粗灰分分别较对照组显著提高7.07%(P<0.05)和8.78%(P<0.05),粗脂肪降低了13.00%(P<0.05)。

摘  要：
The Jifu strain of Nile tilapia Oreochromis niloticus [body weight of(1.29±0.25) g] were fed with five isonitrigenous(32% protein) and isoenergetic(16 kJ·g-1 gross energy) diets with 0%,10%,20%,30%,40% cassava meal for 56 days,each treatment was triplicate.The weight gain(WG),feed coefficient(FC),protein efficiency ratio(PER),apparent digestibility(AD) and body composition of tested fish were measured.The cassava meal might improve growth and feed utilization of tested fish.The WG,FC and PER of the fish fed with 40% cassava meal were 1470.99%(P<0.05),2.36(P<0.05) and 1.27(P<0.05) respectively.The dry matter AD and the protein AD of the fish fed with 40% cassava meal were 79.51% and 94.83%,which were 13.87% and 7.93% more than those of the control(P<0.05).The lipid AD of the fish fed with 40% cassava meal was 94.73%,which was lower than that of the control(P<0.05).The contents of crude protein and ash of the fish body in 40% cassava meal group were 7.07% and 8.78% higher than those of the control(P<0.05),but the content of its crude lipid was 13.00% lower than that in the control(P <0.05).30%-40% cassava meal in the diet of tested fish was suggested.
